The work of preparing International Standards is normally carried out thro

12、ugh 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 liaison with ISO, also take part in the work. ISO collabor

13、ates closely with the International Electrotechnical 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

14、 least75% of the member bodies casting a vote. International Standard ISO8581 was prepared by Technical Committee ISO/TC42, Photography.iv blankISO8581:1994(E) BSI 02-2000 1 Introduction The rapid increase in demand for electronic flash equipment has resulted in the enormous production of an unlimit

15、ed number of types of electronic photoflash equipment, and the lack of International Standards for connectors between the flash unit and the synchro-cord to camera shutters has resulted in the proliferation of new designs of connectors which has continued to grow at an alarming rate. In 1973, ISO/TC

16、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 equipment. 1 Scope This International Standard specifies

17、 the electrical connectors (plugs and sockets) to be used for electronic photoflash equipment. 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

18、 of a mains supply to the flash equipment (seeIEC83 and IEC320), nor those intended for the connection of hand-held cameras to the flash equipment synchro-cord (seeISO519). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions

19、of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards ind
