6.4.1.6 Periodic Inspection and Test

6.4.1.6.1 Refillable cylinders must be subjected to periodic inspections and tests by a body authorized by the appropriate national authority, in accordance with the following:

(a) check of the external conditions of the cylinder and verification of the equipment and the external markings; (b) check of the internal conditions of the cylinder (e.g. internal inspection, verification of minimum wall

thickness);

(c) checking of the threads if there is evidence of corrosion or if the fittings are removed;

Notes:

1. With the agreement of the appropriate national authority, the hydraulic pressure test may be replaced by a test using a gas, where such an operation does not entail any danger.

2. With the agreement of the appropriate national authority, the hydraulic pressure test of cylinders may be replaced by an equivalent method based on acoustic emission, testing or a combination of acoustic emission testing and ultrasound examination. ISO 16147:2006 may be used as a guide for acoustic emission testing procedures.

3. The hydraulic pressure test may be replaced by ultrasonic examination carried out in accordance with ISO 10461:2005+A1:2006 for seamless aluminium alloy gas cylinders and in accordance with ISO 6406:2005 for seamless steel gas cylinders.

(e) check of service equipment, other accessories and pressure-relief devices, if to be reintroduced into service.

Note:

For the periodic inspection and test frequencies, see Packing Instruction 200 or, for a chemical under pressure Packing Instruction 218.

6.4.1.6.2 Cylinders intended for the transport of UN 1001 Acetylene, dissolved and UN 3374 Acetylene, solvent free must be examined only as specified in 6.4.1.6.1 a), c) and e). In addition, the condition of the porous material (e.g. cracks, top clearance, loosening, settlement) must be examined.

6.4.1.6.3 Pressure relief valves for closed cryogenic receptacles must be subject to periodic inspections and tests.

SECTION 7 – MARKING AND LABELLING

7.1 Marking

7.1.4 Markings for Overpacks

7.1.4.1 Unless all markings representative of all dangerous goods in the overpack are clearly visible, the overpack must be marked with:

• the word “overpack”;

• the required markings of 7.1.5.1(a), (b), (e) through (i); • the required markings of 7.1.5.4;

• the required markings of 7.1.6.1, 7.1.6.2 and 7.1.6.3;

• any special handling instructions appearing on packages inside the overpack.

Package specification marking must not be reproduced on the overpack as the word “Overpack” indicates that packages contained within, comply with the prescribed specifications. When packages containing dangerous goods in limited quantities are placed in an overpack, the outside of the overpack must also be marked with the limited quantity marking shown in Figure 7.1.A unless the limited quantity marking on the packages is visible. For an overpack containing packages of radioactive material, see 10.7.1.4.

7.1.4.2 When a consignment consists of more than one overpack, to facilitate identification, loading and notification, the operator requires each overpack to show an identification mark (which may be in any alpha- numeric format) and the total quantity of dangerous goods, as indicated on the Shipper's Declaration. 7.1.5 Packaging Use Marking (Packages and Salvage Packagings)

7.1.5.1 General

Unless otherwise specified in these Regulations, each package containing dangerous goods must be marked, durably and legibly on the outside of the package with each of the following:

(a) the PROPER SHIPPING NAME(S) of the contents (see 8.1.3) (supplemented with the technical name or chemical group name(s) if appropriate) and the corresponding UN NUMBER(S) or ID NUMBER(S) preceded by the letters “UN” or “ID” as applicable, as listed in Subsection 4.2–List of Dangerous Goods. The size of these package markings is set out in 7.1.5.5. In the case of unpackaged articles, these markings must be displayed on the article, on its cradle or on its handling, storage or launching device. For Class 1,

Explosives, the Proper Shipping Name may be supplemented by additional descriptive text to indicate commercial or military names. Example of Proper Shipping Name and UN Number marking:

CORROSIVE LIQUID, ACIDIC, ORGANIC, N.O.S. (CAPRYLYL CHLORIDE) UN 3265.

For solid substances, unless the word “molten” is already included in the Proper Shipping Name, it must be added to the Proper Shipping Name on the package when a substance is offered for air transport in the molten state (see 8.1.3.6).

Note:

Additional descriptive text in the entries in Column B of the List of Dangerous Goods are not part of the Proper Shipping Name but may be used in addition to the Proper Shipping Name.

(b) the full NAME AND ADDRESS of the shipper and the consignee must be provided on each package and should be located on the same surface of the package near the proper shipping name marking, if the package dimensions are adequate;

(c) except for ID 8000, Consumer commodity and packages containing radioactive material (Class 7) the NET QUANTITY of dangerous goods contained in each package must be shown. Where the maximum quantity shown in Columns H, J or L in Subsection 4.2 is a gross weight, the GROSS WEIGHT of the package must be shown. This quantity must be marked adjacent to the UN number and Proper Shipping Name required by (a), above. Where the weight shown on the Shipper's Declaration is a gross weight and the letter “G” is
