This document presents rules for the drafting and presentation of European Standards dealing with machinery safety and their revisions, primarily to achieve consistency and acceptable quality of the various standards to be prepared.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 that are additional to the CEN/CENELEC Internal Regulations, Part 3, when this is necessary owing to the special requirements of machinery safety standards.This document is primarily intended for the drafting of type-C standards. It is also applicable to the drafting of type-B standards; however, the foreseeable variation in the format of these standards prevents general application. When its requirements are specific to type-B standards, this is indicated.
