规定了带有独立输入和输出绕组的单相变压器的一般要求和安全要求，该变压器用于50/60 Hz、高达1000伏的交流电源，空载输出电压超过1000伏，但不超过10000伏，用于为电子广告标志、光信号和类似用途提供冷阴极照明。本标准与IEC 1050:1991（包括勘误表1:1992和修改件1:1994）相同，并根据IEC 1050:1991复制。

Specifies general and safety requirements for single-phase transformers with separate input and output windings, for use on an a.c. supply up to 1000 volt at 50/60 Hz and having a no-load output voltage exceeding 1000 volt but not exceeding 10 000 V and intended for the supply of cold cathode lighting for electric advertising signs, light signals and similar purposes. This Standard is identical with and has been reproduced from IEC 1050:1991, including Corrigendum 1:1992 and Amendment 1:1994.
