The work of preparing International Standards is normally carried out through Iso technical committees.Each member body interested in a subjectfor which a technical committee has been established has the right to be represented on that committee. International ISocollaboratescloselywiththeInternational Electrotechnical Commission(IEC)onall mattersof electrotechnical standardization. Theproceduresusedtodevelopthisdocumentandthose intended foritsfurthermaintenanceare described in the IsO/IEC Directives, Part 1.In particular the different approval criteria needed for the differenttypesof Is
