CEN/TC 143/WG 5 - Electro-discharge - Safety

This document specifies safety requirements and/or protective measures applicable to EDM equipment and EDM systems intended to be adopted by persons undertaking their design, construction, installation and/or supply, such as:
—    manually controlled EDM die sinking or EDM drilling machines;
—    numerically controlled EDM die sinking or EDM drilling machines; and
—    numerically controlled EDM wire cutting machines.
This document also includes information to be provided by the manufacturer to the user.
This document is not applicable to arc eroding and electro-chemical machining equipment.
This document takes account of the precondition of the intended use as well as the reasonably foreseeable misuse, in normal workshop environments and non-explosive atmospheres, including transportation, installation, setting, maintenance, repair and dismantling for removal or disposal of EDM equipment and EDM systems.
This document is also applicable to auxiliary devices essential for EDM processing.
This document deals with all significant hazards, hazardous situations or hazardous events relevant to EDM equipment and EDM systems, where they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document is intended to apply to machines manufactured after the date of publication of this document.
When requirements of this type-C standard are different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of other standards for machines that have been designed and built according to the requirements of this type-C standard.
This document defines required performance level and safety categories of the safety-related parts of the control system for EDM equipment and EDM systems as defined in ISO 13849-1:2015.

This International Standard specifies safety requirements and/or protective measures, applicable to EDM equipment and EDM systems, such as - manually controlled EDM die sinking or EDM drilling machines, - numerically controlled EDM die sinking or EDM drilling machines, and - numerically controlled EDM wire cutting machines intended to be adopted by persons undertaking the design, construction, installation and/or supply of such equipment.
