The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body i

3、nterested 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 liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechn

4、ical Commission (IEC) on all matters of electrotechnical standardization. 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.

7、as resulted in the enormous production of an unlimited number of types of electronic photoflash equipment, and the lack of International Standards for connec- tors between the flash unit and the synchro-cord to camera shutters has resulted in the proliferation of new designs of connectors which has

8、con- tinued to grow at an alarming rate. In 1973, ISO/TC 42 decided to develop a standard for the above object. The aim of this International Standard is to minimize the faulty connection of plugs by amateur photographers and also to reduce the number of types of connectors used for electronic flash

10、nt. It gives a limited number of connectors and the dimensions to be used for the connection between flash unit and flash synchro- cords. It does not cover those connectors which are intended for the connection of a mains supply to the flash equipment (see IEC 83 and IEC 3201, nor those intended for

11、 the connection of hand-held cameras to the flash equipment synchro-cord (see IS0 519). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
