The work of prepari
11、ng 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. International organizations, governmental and non-governmental, in lia
12、ison 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 with the rules given in the ISO/IEC Directives, Part 3. Draft Internation
13、al 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 part of ISO 10349
14、may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 10349-13 was prepared by Technical Committee ISO/TC 42, Photography. ISO 10349 consists of the following parts, under the general title Photography Photogr
15、aphic-grade chemicals Test methods: Part 1: General Part 2: Determination of matter insoluble in water Part 3: Determination of matter insoluble in ammonium hydroxide solution Part 4: Determination of residue after ignition Part 5: Determination of heavy metals and iron content Part 6: Determination
