BS EN 61558-2-1:1998 IEC 61558-2-1:1997 Incorporating Amendment No. 1
Safety of power transformers, power supply units and similar — Part 2.1 Particular requirements for separating transformers for general use
This British Standard is the English language version of EN 61558-2-1:1997.
It was derived by CENELEC from IEC 61558-2-1:1997.
The BS EN 61558 series of standards will ultimately supersede BS 3535-1,
dual numbered as BS EN 60742:1996, and BS 3535-2. Until that time arrives,
these latter standards are only to be used for equipment not covered by the
BS EN 61558 series.
