The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.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 11334-4 was prepared by Technical Committee ISO/TC 173, Technical systems andaids for disabled or handicapped persons.ISO 11334 consists of the following parts, under the general title Walking aids manipulated by one arm —Requirements and test methods:¾ Part 1: Elbow crutches¾ Part 4: Walking sticks with three or more legsAnnex A of this part of ISO 11334 is for information only.SIST EN ISO 11334-4:2000
