8、 the direction of the Electrotechnical Sector Board and is the English language version of EN 55022:1994, Limits and methods of measurement of radio disturbance characteristics of information technology equipment, including amendment A1:1995 and amendment A2:1997, published by the European Committee
9、 for Electrotechnical Standardization (CENELEC). It is derived from CISPR 22:1993 including Amendment 1:1995 and Amendment 2:1997, published by the International Electrotechnical Commission (IEC). The CENELEC common modifications given in EN 55022/A2:1997 have been implemented at the appropriate pla
10、ces in the text and are indicated by a single line in the margin. Reference is made in the foreword of EN 55022:1994 to the fact that for products which conform to EN 55022:1987 before 31 December 1995, as shown by the manufacturer or by a certification body, the previous standard may continue to ap
11、ply for production until 31 December 1998. For this reason BS 6527:1988, which is superseded by this British Standard, will be withdrawn but may still be referred to in these circumstances. CISPR 22:1993 has now been revised as CISPR 22:1997. When it is ratified by CENELEC it will be published as a
12、new edition of BS EN 55022. 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 with a British Standard does not of itself confer immunity from legal obligations. Cross-referen
