The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for represented on that committee. International organizations, governmental and non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards 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.

A form of hand-lever-operated testing and/or set- ting equipment for injectors has evolved over the years; it has been found in principle effective and adequate to perform the test. Differences in certain physical values between equipment from different manufacturers and of different designs have however resulted in lack of correlation of results. This International Standard consists of two parts (apparatus and to establish common test conditions. ili by IHS under license with IS Not for Resale
