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 been established has the right to be 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 (EC)onallmattersofelectrotechnicalstandardization. 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. International Standard ISO 12103-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on road vehicles. IsO 12103 consists of the following parts, under the general title Road vehicles Test dust for filter evaluation: Part 1: Arizona test dust Part2:Aluminiumoxidetestdust Annexes A to C of this part of ISO 12103 are for information only.
