15、ronic Equipment Standards Committee. It is identical with IEC Publication 489-2:1978 “Methods of measurement for radio equipment used in the mobile services. Part 2: Transmitters employing A3 or F3 emissions”, published by the International Electrotechnical Commission (IEC). This Part should be read
16、, where applicable, in conjunction with Part 1 of this standard. NOTEThe emission designations A3 and F3 used in this British Standard are those which were given in Article 2 of the ITU1) Radio Regulations prior to the World Administrative Radio Conference held in 1979 (WARC 79). New designations fo
17、r emissions were agreed at WARC 79 and will be incorporated into this British Standard when the changes are made to the corresponding part of IEC Publication 489. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard w
18、ithout deviation. Some terminology and certain conventions are not identical with those used in British Standards. There is no corresponding British Standard for IEC 244-6, referred to in 9.6.1. The Technical Committee has reviewed the provisions of IEC 244-6 and has decided that they are acceptable
19、 for use in conjunction with this standard. There are no corresponding British Standards for IEC 106, IEC 244-1, and C.I.S.P.R. Publications No. 2 and No. 4 but the references are for information only and therefore the validity of this standard is not affected. NOTETextual errors. In clause 1, line
20、2, “10 KHz” should be read as “10 kHz”. In 16.1.2, items b) and d), the unit, for signal level should be read as “dB (4V)”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance
21、with a British Standard does not of itself confer immunity from legal obligations.
