17、al decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the National Committees having a special interest therein are represented, express, as nearly as possible, an international consen- sus of opinion on the subjects dealt with. 2) They have the fo
18、rm of recommendations for intemational use and they are accepted by the National Committees in that sense. 3) In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the text of the IEC recommendation for their national rules in so far as n
19、ational conditions will permit. Any divergence between the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter. 4) The IEC has not laid down any procedure concerning marking as an indication of approval and has no responsibility when
20、 an item of equipment is declared to comply with one of its recommendations. PREFACE This standard has been prepared by Sub-committee 60A: Sound Recording, of IEC Technical Committee No. 60: Recording. This standard should be used in conjunction with Parts 1, 3 and 6 of IEC Publication 94, the title
21、s of which are given below, with IEC Publication 461 (1986) : Time and control code for video tape recorders, and with IEC Publication 130-XY: Circular connectors for low-frequency audio applications such as radio and associated sound equipment (in preparation).
