The work of preparing International Standards is normally carried out through ISO non-governmental, in liaison with IsO, also take part in the work. IsoO collaborates closely y 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. The main task of technical committees is to prepare International Standards. 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 24135 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety ofpowered industrialtrucks.
