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 (IEC) on all matters of electrotechnical standardization International Standards are drafted in accordance with the rules given in the ISO/lEc Directives, Part 2. adoptedbythetechnicalcommitteesarecirculatedtothememberbodiesforvoting.Publicationasan International Standard requires approval by at least 75 % of the member bodies casting a vote. rights.

Multinational continents.Themixtureof specificationsandstandardscombinetoincreasethechancesof maintenance errors, no more so than in the interconnection system. Power plant manufacturers in France may use conductors and terminations manufactured in Europe mating at the firewall with terminations and conductors equipment. The requirement for close or “clipped" tolerance, lightweight conductors can provide the opportunity to address many of these problems by overcoming the long-standing issue of AwG versus metric sizes. This revision of isO 2635 introduces a list of lightweight conductors for airframe cables. This list supplements the existing list of standard metric conductors which has not received worldwide acceptance. The list is derived from NEMA standard WC 67 which includes the constructions in previous and existing specifications used by airframe constructors. The conductor codes in Table 1 are taken from WC 67. The constr
