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(EC)on all matters of electrotechnical standardizationInternational Standards are drafted in accordance with the rules given in the iSo/EC Directives, Part 3Draft International Standards adopted by the technical committees are circulated to the member bodies for votingPublication as an International Standard requires approval by at least 75 of the member bodies casting a voteAttention is drawn to the possibility that some of the elements of this part of iso 15031 may be the subject of patentrights.
