PREFACE

This report is an overview of available standards (IEC, ISO, EN and other standards) applicable within physical asset and maintenance management projects.

The standards are not described in detail, purpose of this document is to list a set of standards (including a short description) relevant for asset, engineering and maintenance management projects. The interested reader should check the details in the standard(s) itself.

'The nice thing about standards is that there are so many to choose from.' (Andrew Stuart Tanenbaum)

"How can something "standard" contribute to something as creative as "engineering" ?

2 Standards and the organization

Many maintenance organizations and especially maintenance and availability engineers, have a "love/hate" relationship with standards. Most engineers realize that standards contain a wealth of helpful information and that working to certain standards is wise and often mandatory. However, there is a simple dichotomy between the words "engineer" and "standard" - How can something "standard" contribute to something as creative as “engineering" ? Also, with the plethora of standards available - corporate, industry, national, regional, international,

government - finding all of the right, most useful standards can be a daunting task that many engineers would rather not pursue.

Successful organizations know how to find the right standards and use them as the foundation for maintenance that is innovative, socially responsible, and cost-effective. Each of the

disciplines underneath benefits in different ways from the standards.

 Research, Design and Development

 Manufacturing and Operations

 Quality Control

 Sales and Marketing

 Maintenance and Repair

Research, Design and Development

The initial stages of any product lifecycle represent both a vital investment for long-term business success and a constant challenge to minimize that investment. Time is one of the greatest factors in minimizing R&D costs and maximizing return on investment (ROI). Manufacturing Operations

When the designed product is handed off to manufacturing, the challenge of minimizing time to market and maximizing ROI remain in place, though the standards-related strategies for meeting those challenges differ.

The discipline of manufacturing builds on the R&D process by further incorporating Product Data Management (PDM), Product Lifecycle Management (PLM), and Enterprise Resource Planning (ERP) systems, all while monitoring the engineering process for standards compliance.

In manufacturing, maximizing ROI means avoiding engineering change orders, redesigns, and production downtime, which is often a function of having a centralized information management solution that integrates and accommodates all the various documents and applications inherent to the manufacturing process.

Quality Control

Throughout the processes of manufacturing, maintenance and repair, the discipline of quality control acts to limit your company's product liability and maximize ROI, all while relying on documents such as specifications, industry regulations, safety codes, reports and tracking, and more.

(10)

Page 10 of 54

Quality products and services are invariably built upon quality information and standards. As the amount of information your quality control team has at its manageable disposal increases, the results are:

 superior testing reports

 faster decision-making

 better quality products

 increased productivity

Sales and Marketing

While standards may not be traditionally associated with the disciplines of sales and marketing, any good salesperson will tell you how important it is to know your market. Any salesperson, regardless of their engineering status, will generate more sales and company profitability when armed with:

 a thorough technical understanding of your product

 documentation on industry standards or regulations that ensure customers of product

compliance

 valuable intelligence on competitors' manufacturing processes and products

 potential leads in the form of companies that may need your products or components

Maintenance and Repair

Standards guide both successful companies and products from beginning to end. In the case of products, the end of the lifecycle is best represented by maintenance and repair, which comes with its own standards-related challenges, such as:

 accessing detailed parts information and historical specs and standards

 identifying and procuring replacement parts, whether common or hard to find, new or

old

 researching alternatives for obsolete parts and finding stocking vendors

In each of these cases, the issue of compliance remains front and centre. Working confidently with a combination of replacement and historical standards as well as alternative parts is possible with the help of up-to-date, verified industry document resources.

3 IEC Standards

3.1 IEC as a standardization organization:

The International Electrotechnical Commission is the international standards and conformity assessment body for all fields of electrotechnology.

Founded in 1906, the International Electrotechnical Commission (IEC) is the global organization that prepares and publishes international standards for all electrical, electronic and related technologies. The IEC was founded as a result of a resolution passed at the International Electrical Congress held in St. Louis (USA) in 1904. The membership consists of more than 60 participating countries, including all the world's major trading nations and a growing number of industrializing countries.

3.2 CENELEC and IEC:

CENELEC and the International Electrotechnical Commission operate at two different levels but it is self-evident that their actions have a strong mutual impact since they are the most important standardization bodies in the electrotechnical field.

Collaboration has always been felt necessary. Co-operation between CENELEC and the IEC is described in what is known as "the Dresden Agreement" since it was approved and signed by both partners in the German city in September 1996.This agreement (which relates to common planning of new work and parallel CENELEC/IEC voting) intends:

 to expedite the publication and common adoption of International Standards;

 to ensure rational use of available resources and therefore should full technical

consideration of the content of the standard preferably take place at international level;

 to accelerate the standards preparation process in response to market demands.

3.3 How the IEC defines a standard:

A standard (as defined in IEC/ISO Guide 2) is a document, established by consensus and approved by a recognized body, that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context. An international standard is a standard adopted by an international standardizing/standards organization and made available to the public.

The definition given in all IEC standards reads: "A normative document, developed according to consensus procedures, which has been approved by the IEC National Committee members of the responsible committee in accordance with Part 1 of the ISO/IEC Directives as a committee draft for vote and as a final draft International Standard and which has been published by the IEC Central Office."

3.4 IEC 60079: Electrical apparatus for explosive gas atmospheres

Electrical installations in hazardous areas possess features specially designed to render them suitable for operation in such atmospheres. It is essential, for reasons of safety in those areas, that, throughout the life of such installations, the integrity of those special features is preserved; they therefore require initial inspection and either

 regular periodic inspections thereafter, or

(12)

Page 12 of 54

in accordance with this standard and, when necessary, maintenance.

3.4.1 Part 17: Inspection and maintenance in hazardous areas (other than mines)

This part of IEC 60079 is intended to be applied by users, and covers factors directly related to the inspection and maintenance of electrical installations within hazardous areas only. It does not include conventional requirements for electrical installations, nor the testing and certification of electrical apparatus.

3.5 IEC 60300: Dependability management:

3.5.1 Part 1: Dependability management systems

Describes the concepts and principles of dependability management systems. Identifies the generic processes in dependability for planning, resource allocation, control, and tailoring necessary to meet dependability objectives. Deals with the dependability performance issues in the product life-cycle phases concerning planning, design, measurements, analysis and

improvement. Dependability includes availability performance and its influencing factors: reliability performance, maintainability performance, and maintenance support performance. Aims at facilitating co-operation by all parties concerned (supplier, organization and customer) and fostering understanding of the dependability needs and value to achieve the overall dependability objectives.

3.5.2 Part 2: Guidelines for dependability management

Provides guidelines for dependability management of product design, development, evaluation and process enhancements. Life cycle models are used to describe product development or project phases. Applicable for detailed planning and implementation of a dependability programme to meet specific product needs.

3.5.3 Part 3-1: Application guide - Analysis techniques for dependability - Guide on methodology

Gives a general overview of commonly used dependability analysis techniques. It describes the usual methodologies, their advantages and disadvantages, data input and other conditions for using various techniques. It is an introduction to selected methodologies and is intended to provide the necessary information for choosing the most appropriate analysis methods. 3.5.4 Part 3-2: Application guide - Collection of dependability data from the field This part of IEC 60300 provides guidelines for the collection of data relating to reliability,

maintainability, availability and maintenance support performance of items operating in the field. It deals in general terms with the practical aspects of data collection and presentation and briefly explores the related topics of data analysis and presentation of results. Emphasis is made on the need to incorporate the return of experience from the field in the dependability process as a main activity.

3.5.5 Part 3-3: Application guide - Life cycle costing

This part of IEC 60300 provides a general introduction to the concept of life cycle costing and covers all applications. This standard is intended for general application by both customers (users) and suppliers of products. It explains the purpose and value of life cycle costing and outlines the general approaches involved. It also identifies typical life cycle cost elements to facilitate project and programme planning.

(13)

3.6 IEC 60706: Maintainability of equipment:

3.6.1 Part 1: Introduction, requirements and maintainability programme

This standard is intended to make recommendations for maintainability practices, and to simulate ideas in the maintainability field. Organizations acquiring items will find the standard useful in assisting them in defining maintainability requirements and associated programmes.

(14)

Page 14 of 54

Item suppliers will benefit from use of the standard, gaining an understanding of the requirements for achieving and verifying maintainability objectives.

3.6.2 Part 2: Maintainability requirements and studies during the design and development phase

This part of IEC 60706 examines the maintainability requirements and related design and use parameter, and discusses some activities necessary to achieve the required maintainability characteristics and their relationship to planning of maintenance. It describes the general approach in reaching these objectives and shows how maintainability characteristics should be specified in a requirements document or contract. It is not intended to be a complete guide on how to specify or to contract for maintainability. Its purpose is to define the range of

considerations when maintainability characteristics are included as requirements for the development or the acquisition of an item.

3.6.3 Part 3: Verification and collection, analysis and presentation of data

This part of IEC 60706 describes the various aspects of verification necessary to ensure that the specified maintainability requirements of an item have been met and provides suitable

procedures and test methods. This standard also addresses the collection, analysis and

presentation of maintainability related data, which may be required during, and at the completion of, design and during item production and operation.

3.6.4 Part 4: Maintenance and maintenance support planning

This section of the guide describes the tasks required for planning of maintenance and

maintenance support. They should be performed during the system acquisition phase in order to meet the availability objectives in the operational phase. The interfaces between reliability, maintainability and the maintenance support planning programme and their tasks are also described.

3.6.5 Part 5: Testability and diagnostic testing

This guide has for purpose to provide guidance for the early consideration of testability aspects in design and development, and to assist in determining effective test procedures as an integral part of operation and maintenance. This second edition constitutes a technical revision. It expands and provides more detail on the techniques and systems broadly outlined in the first edition.

3.6.6 Part 6: Statistical methods in maintainability evaluation

The part of IEC 60706 is applicable to the tasks of maintainability, allocation, maintainability demonstration and maintainability data evaluation, as described in sections five, six and seven, respectively of the guide.

3.7 IEC 60812: Analysis techniques for system reliability - Procedure for failure mode and

effects analysis (FMEA)

(15)

Page 15 of 54

3.8 IEC 61025: Fault tree analysis (FTA)

This International Standard describes fault tree analysis and provides guidance on its application as follows:

 definition of basic principles;

 describing and explaining the associated mathematical modelling;

 explaining the relationships of FTA to other reliability modelling techniques;

 description of the steps involved in performing the FTA;

 identification of appropriate assumptions, events and failure modes;

 identification and description of commonly used symbols.

3.9 IEC 61070: Compliance test procedures for steady-state availability

This International Standard specifies techniques for availability performance testing of frequently maintained items when the availability performance measure used is either steady-state availability or steady-state unavailability. It is applicable to compliance testing of the steady-state availability of items attaining only two states, up-state and down-state, under the following conditions:

 One single repaired item.

 All up times have the same exponential distribution.

 Preventive maintenance time is not included in down time although it is recognized

as having possible impact on availability performance.

 All contributors to down time need to be explicitly stated in the requirement or test

specification.

 Very reliable items may require an extremely long test time to determine

compliance.

 The compliance test procedures use the complementary measure steady-state

unavailability.

3.10 IEC 61078: Analysis techniques for dependability - Reliability block diagram and boolean

methods

This International Standard describes procedures for modelling the dependability of a system and for using the model in order to calculate reliability and availability measures.

The RBD (Reliability Block Diagram) modelling technique is intended to be applied primarily to systems without repair and where the order in which failures occur does not matter. For systems where the order of failures is to be taken into account or where repairs are to be carried out, other modelling techniques, such as Markov analysis, are more suitable.

It should be noted that although the word “repair” is frequently used in this standard, the word “restore” is equally applicable. Note also that the words “item” and “block” are used extensively throughout this standard: in most instances interchangeably.

3.11 IEC 61164: Reliability growth - Statistical test and estimation methods

This International Standard gives models and numerical methods for reliability growth assessments based on failure data, which were generated in a reliability improvement programme. These procedures deal with growth, estimation, confidence intervals for product reliability and goodness-of-fit tests.

The reference designation identifies objects for the purpose of correlating information about an object among different kinds of documents and the products implementing the system. For manufacturing, installation and maintenance purposes, the reference designation or part of it may also be shown on or near the physical part corresponding to the object. The principles laid down are general and are intended to be applicable to all technical areas. They can be used for systems based on different technologies or for systems combining several technologies. It should be noted that this standard provides a number of possibilities for the construction of reference designations. For most applications, however, only a subset of the possibilities given need be used.

3.12.2 Part 2: Classification objects and codes for classes

This part of IEC 61346 defines object classes and associated letter codes for these classes to be used in reference designations.

The classification schemes are applicable for objects in all technical areas and may be applied at any position in a tree-like structure set up in accordance with IEC 61346-1.

3.12.3 Part 4: Discussion of concepts

(18)

Page 18 of 54

This International Standard specifies requirements and makes recommendations for the design, integration and validation of safety-related electrical, electronic and programmable electronic control systems (SRECS) for machines. It is applicable to control systems used, either singly or in combination, to carry out safety-related control functions on machines that are not portable.

3.21 IEC 62079: Preparation of instructions – Structuring, content and presentation

This standard provides general principles and detailed requirements for the design and formulation of all types of instructions that will be necessary or helpful for products of all kinds ranging from small, simple ones, such as a tin of paint, to large or highly complex ones, such as a large industrial installation. It is intended for application by

 product manufacturers, technical writers, technical illustrators, software designers,

translators or other people engaged in the work of conceiving and drafting such instructions;

 authorized representatives of the product manufacturer in the country of product

installation and/or usage.

It will also be helpful in contract negotiations between product supplier and customer. This standard does not establish a fixed amount of documentation that has to be delivered together with a product. This would obviously not be possible because this standard has to be valid for all kind of products but the amount of documentation very much depends on the complexity of the product. Therefore this standard lists all possible kinds of instructions one can think of. What this standard does aim to standardize is how such instructions are to be prepared. No general standard can provide comprehensive information covering each special case. This International Standard, therefore is to be used in conjunction with the requirements of specific product standards or, where no such standards exist, with the relevant requirements of standards for similar products.

3.22 IEC 62198: Project risk management - Application guidelines

4 ISO Standards

4.1 ISO as an organization:

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies) from more than 140 countries, one from each country. The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whom a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO

collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

4.2 ISO 13374: Condition monitoring and diagnostics of machines – Data processing,

communication and presentation 4.2.1 Part 1: General guidelines

These principles of risk assessment bring together knowledge and experience of the design, use, incidents, accidents and harm related to machinery in order to assess the risks posed during the relevant phases of the life cycle of a machine.

ISO 14121-1 provides guidance on the information that will be required to enable risk

(21)

Page 21 of 54

and evaluating risk. It also gives guidance on the making of decisions relating to the safety of machinery and on the type of documentation required to verify the risk assessment carried out. 4.4.2 Part 2: Practical guidance and examples of methods

ISO/TR 14121-2 gives practical guidance on the conducting of risk assessments for machinery in accordance with ISO 14121-1 and describes various methods and tools for each step in the process.

It also provides practical guidance on risk reduction (in accordance with ISO 12100) for machinery, giving additional guidance on the selection of appropriate protective measures for achieving safety.

The intended users of ISO/TR 14121-2 are those involved in the integration of safety into the design, installation or modification of machinery (e.g. designers, technicians, safety specialists).

4.5 ISO 14224: Petroleum, petrochemical and natural gas industries - Collection and

exchange of reliability and maintenance data for equipment: This international standard focuses on the two main issues:

Data requirements for the type of data to be collected for use in various analysis methodologies Standardised data format to facilitate the exchange of reliability and maintenance data between plants, owners, manufacturers and contractors

The main areas where such data are being used are: Reliability, e.g. failure events and failure mechanisms

Availability/efficiency, e.g. equipment availability, system availability, plant production availability Maintenance, e.g. corrective and preventive maintenance, maintenance supportability

Safety and environment, e.g. equipment failures with adverse consequences for safety and/or environment

The following main categories of data are to be collected:

1. Equipment data, e.g. equipment taxonomy, equipment attributes

2. Failure data, e.g. failure cause, failure consequence

3. Maintenance data, e.g. maintenance action, resources used, maintenance consequence, down time

Standardisation of data collection practices facilitates the exchange of information between relevant parties e.g. plants, owners, manufacturers and contractors throughout the world. This standard establishes requirements that any in-house or commercially available RM data system shall meet when designed for RM data exchange. Examples/guidelines/principles for how to exchange and merge such RM data is addressed.

The data collection principles and associated terms & definitions defined in this standard do also constitute a "reliability language" which can be useful for communicating operational experience. The failure modes defined in the normative part of this International Standard is meant to be a "Reliability thesaurus" for various quantitative as well as qualitative applications.

5 MIL Standards

5.1 Defence and military standards

A United States Defence Standard, often called a military standard, "MIL-STD", or "MIL-SPEC", is used to help achieve standardization objectives by the U.S. Department of Defence.

Standardization is beneficial in achieving interoperability, ensuring products meet certain requirements, commonality, reliability, total cost of ownership, compatibility with logistics systems, and similar defence-related objectives.

Defence Standards are also used by other non-Defence government organizations, technical organizations, and industry. This article discusses definitions, history, and usage of Defence Standards. Related documents, such as Defence Handbooks and Defence Specifications are also addressed.

5.2 MIL-HDBK-189: Reliability growth management

This handbook provides procuring activities and development contractors with an understanding of the concepts and principles of reliability growth, advantages of managing reliability growth, and guidelines and procedures to be used in managing reliability growth. It should be noted that this handbook is not intended to serve as a reliability growth plan to be applied to a program without any tailoring. This handbook, when used in conjunction with knowledge of the system and its development program, will allow the development of a reliability growth management plan that will aid in developing a final system that meets its requirements and lowers the life cycle cost of the fielded systems.

This handbook is intended for use on systems / equipments during their development phase by both internal and external personnel.

5.3 MIL-STD-721C: Definitions of terms for reliability and maintainability

6 EN / CEN Standards

6.1 CEN as an organization

CEN (= Comité Européen de Normalisation / European Committee for Standardization) is one of the two components of the Joint European Standards Institution CEN/CENELEC.

CEN constitutes a "European forum" in the field of non-electrotechnical standardization, facilitating and organizing contacts with all interested parties: governments, public bodies, producers, users, consumers, trade unions, etc...

The aim of CEN may be realized in any way, and in particular by the following means:

 Harmonization of national standards published by CEN members;

 Promotion of uniform implementation of International Organization for Standardization

(ISO) and other international standards or recommendations by CEN members;

 Preparation of reports on the state of harmonization of standards of CEN members;

 Preparation of European Standards (EN) 'de novo' when justified by requirements in

Western Europe where no appropriate international or other standard exists for use as a reference document;

 Provision of procedures for the mutual recognition of test results and certification

systems on the European level;

 Support for world-wide standardization in the International Organization for

Standardization (ISO);

 Co-operation with the European Communities, the European Free Trade Association

(EFTA) and other international governmental organizations so that European Standards (EN) and Harmonization Documents (HD) can be referred to in their directives or other instruments;

 Co-operation with other international governmental, economic, professional and scientific

organizations on questions linked with standardization;

 Co-operation with the European Committee for Electrotechnical Standardization

(CENELEC), the other component of the Joint European Standards Institution.

6.2 EN 1050: Safety of machinery - Principles of risk assessment

This standard establishes general principles for the procedure known as risk assessment by which the knowledge and experience of the design, use, incidents, accidents and harm related to machinery is brought together in order to assess the risks during all phases of the life of the machinery.

This standard gives guidance on the information required to allow risk assessment to be carried out. Procedures are described for identifying hazards and estimating and evaluating risk. The purpose of the standard is to provide advice for decisions to be made on the safety of machinery and the type of documentation required to verify the risk assessment carried out.

This standard is not intended to provide a detailed account of methods for analysing hazards and estimating risk as this is dealt with elsewhere. A summary of some of these methods is given for information only.

Replaced by ISO EN 14121.

(27)

Page 27 of 54

In addition, as technical and economic developments increase, the demand for contracted maintenance services both nationally and across borders also increases. It is therefore important that maintenance contracts are approached in a structured and careful manner. The purpose of this Standard is to:

 promote cross-border company/maintenance contractor relationships and to produce a

clear interface between the company and the maintenance contractor for maintenance services;

 improve the quality of maintenance contracts so that disputes and adjustments are

minimized;

 draw attention to the scope of maintenance services and to identify options for their

provision;

 give assistance in, and advice on, the drafting and negotiation of maintenance contracts

and in specifying arrangements in the case of dispute;

 identify types of maintenance contracts and to make recommendations for the attribution

of rights and obligations between the parties of the contract including risks;

 simplify comparison between maintenance contracts.

The standard also could facilitate in specifying the required output of maintenance activities.

6.4 EN 13306: Maintenance terminology

The purpose of this European standard is to define the generic terms used for all types of maintenance and maintenance management irrespective of the type of item considered except software.

It is the responsibility of any maintenance management to define its maintenance strategy according to three main criteria:

 to ensure the availability of the item for the required function, often at optimum costs;

 to consider the safety requirements associated with the item for both maintenance and

user personnel, and, where necessary, any impact on the environment;

 to uphold the durability of the item and/or the quality of the product or service provided

considering, where necessary, costs.
