As a response to the increased global trade in machinery, the relevant ISO Technical Committees have undertaken publication of a series of related machinery safety standards. It has thus been necessary to develop rules for the preparation, drafting and presentation of such safety standards, supplementing the ISO/IEC Directives Part 2, which sets out general principles and requirements for all International Standards.
ISO Guide 78 presents these rules, primarily to achieve consistency and acceptable quality of the various standards to be prepared.
It is intended for use by Technical Committees writing type-B and type-C standards in the field of safety of machinery. 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.
The document allows users to:
- Determine the necessity for standardization or revision
- Identify hazardous situations or hazardous events
- Estimate and evaluate risks generated by hazards
- Verify compliance with safety requirements
- Implement risk reduction measures.
It also provides 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.
The main revisions in this document are as follows:
— Update of references and their associated requirements with regard to ISO 12100 and the
ISO/IEC Directives Part 2;
— Addition of a further question to the check list to be used to determine the necessity for standardization and/or revision [5.2, question e)];
— Extension of the minimum statement to be given in the Introduction of type B- and type C- standards by a general notice concerning the document’s relevance, in particular, for those stakeholder groups representing the market players with regard to machinery safety (6.3.2 and 6.3.3);
— Addition of the term “risk reduction measure” as a synonym to the term “protective measure” throughout the document;
— Replacement of the term “optional element” by “conditional element” and “compulsory element” by “mandatory element” in accordance with the latest edition of the ISO/IEC Directives, Part 2;
— Change in the title of Annex A;
— Addition of Annex D concerning significant technical changes between a standard and its previous edition, to be added in those cases where the significant technical changes are not already stated in the Foreword.
