Safety of machine tools
CUTTING MACHINES FOR COLD METAL CUTTING
Safety of machine tools. Sawing machines for metal cold cutting
Date of implementation -2010 - 07-011 Scope
This standard specifies requirements for the safety and determine the measures to be taken by persons engaged in the design, manufacture and supply (including assembly / disassembly, transportation and maintenance) cutting machines for cold cutting of metals (ferrous and
non-ferrous) or materials, in part consisting of metal using cutting tools (detachable cutters, circular saws segment, hacksaw blades, band saw continuous). Cutting disc cutters and saws segment will continue to be called disc cutting tool.
This standard provides for the use of the machine for its intended purpose, including the possible misuse of their use, maintenance, adjustment, cleaning, etc. It includes access to the machine from all sides, while it describes a means to reduce the risk to operators and other workers.
This standard also applies to additional devices, unless they are an integral part of the
machine. Where such devices are an integral part of the machine, the designers and manufacturers must ensure the safe connection of these devices to the machine.
