13、 of national standards bodies (ISO member bodies). 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.
14、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 wit
15、h the rules given in the ISO/IEC 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 approv
16、al 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 24431 was prepared by Technical Committe

19、 current practice and experience. Each transportable gas cylinder is inspected at the time of filling in order to establish that: it has no defects which render it unsafe for filling or continued use; it can be identified and complies with the relevant requirements with regard to marking, labelling,
20、 colour coding and completeness of its accessories; its valve functions satisfactorily. The cylinder filling inspection is carried out exclusively by persons who have the appropriate training and competences, so as to ensure that each cylinder is safe for continued use.

This International Standard does not apply to cylinders manifolded in bundles or trailers. This International Standard applies primarily to industrial gases
