1、BRITISH STANDARD Helical-scan digital component video cassette recording system using 19 mm magnetic tape (format D-1) The European Standard EN 61016:2001 has the status of a British Standard ICs 33.160.40 BS EN 61016:2001 NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW BS EN
2、61016:ZOOl Amd. No. National foreword Date Comments This British Standard is the official English language version of EN 61016:2001. It is identical with IEC 61016:1989 (incorporating Amendment 1:1999). The UK participation in its preparation was entrusted to Technical Committee EPU100, Audio, video
3、 and multimedia systems and equipment, which has the responsibility to: - - aid enquirers to understand the text; present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European
4、 developments and promulgate them in the UK. - A list of organizations represented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60037-1. For a
5、period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems.
