The work of preparing International Standards is normally carried out through ISO 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. 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 8668-4 was prepared by Technical Committee ISO/Tc 20, Aircraft and space vehicles, Sub-Committee SC 1, Aerospace electricalrequirements.
