language version of EN 60730-2-11:1993 Automatic electrical controls for household and similar use — Part 2: Particular requirements for energy regulators including amendments A1:1997 and A2:1998, published by the European Committee for Electrotechnical Standardization (CENELEC) It was derived by CENELEC from IEC publication 730-2-11:1993, first edition, including amendment 1:1994 and amendment 2:1997, published by the International Electrotechnical Commission (IEC) No CENELEC common modifications were approved to IEC 730-2-11:1993 However there are CENELEC common modifications to amendment to IEC 730-2-11 and these are indicated by a sideline in the margin This British Standard is to be read in conjunction with BS EN 60730-1:1992 General requirements which it supplements or modifies The many references to Part should be read as references to BS EN 60370-1 which is the English language version of EN 60730-1, which was derived from IEC Publication 730-1:1986, first edition The foreword of EN 60730-2-11 makes reference to the “date of withdrawal”, dow, of the relevant, national standard In this case the relevant national standard is BS 3955 which will cease to be applicable to controls within the scope of BS EN 60730-2-11 on July 1995 Certification and marks will not be awarded after this date with respect to BS 3955 However, such certification and marks, already awarded, may continue to apply to production until July 2000 Product approval Attention is drawn to the fact that products conforming to this British Standard may be approved by the British Electrotechnical Approvals Board for the purposes of participation in the CENELEC Certification Agreement and in the CB Scheme of the IECEE (Details of the BEAB Approval Scheme are given on the inside back cover) 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 Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages to 10, an inside back cover
