This document specifies requirements for the drafting and presentation of European machinery safety standards and standards for safety components, primarily to achieve consistency and acceptable quality, throughout the programme, of the various standards to be prepared (also to meet the requirements of the Mandates from the European Commission).It also gives requirements on the criteria for the selection of new work items and for procedures to prepare, produce or revise standards in an efficient and effective way.This document gives requirements which are additional to the CEN/CENELEC Internal Regulations - Part 3 (based on ISO/IEC Directives, Part 2) when this is necessary because of the special requirements of machinery safety standards and standards for safety components.This document is primarily intended for the drafting of type C standards. It also applies to type B standards but the foreseeable variation in the format of these standards prevents general application. When requirements specifically apply to type B standards, this is indicated.
