The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has beer non-governmental,inliaisonwithIsO,also take part in the work.Iso collaborates closely withthe International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEc Directives, Part 2 adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

It is applicable to electrofusion fittings intended to be used for plastics pipi
