34、his document is a type-C standard as defined in ISO 12100:2010.The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the Scope of this International Standard. In addition, electro-discharge machining (EDM) equipment and EDM systems are

35、intended to be designed according to the principles of ISO 12100 for hazards which are not dealt with in this International Standard.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

36、 over the requirements of other standards for machines that have been designed and built according to the requirements of this type-C standard.This International Standard defines performance level and safety categories of the safety-related parts of the control system for EDM equipment and EDM syste

37、ms as defined in ISO 13849-1:2006.The requirements of this International Standard concern designers, manufacturers, suppliers and importers of machines described in the Scope.This International Standard also includes a list of informative items intended to be provided by the manufacturer to the user
