1. the following British Standards will be withdrawn on 31st december 2012 BS 638-4 Arc welding power sources, equipment and accessories. Specification for welding cables

BS 6007 Electric cables — Single core unsheathed heat-resisting cables for voltages up to and including 450/750 V, for internal wiring

BS 6500 Electric cables — Flexible cords rated up to 300/500 V, for use with appliances and equipment intended for domestic, office and similar environments

BS 7919 Electric cables — Flexible cables rated up to 450/750 V, for use with appliances and equipment intended for industrial and similar environments

2. the introduction of BS en 50525

In 2011 a new European Standard, EN 50525, covering wiring and flexible cables up to and including 450/750 V was issued and it supersedes the earlier harmonisation documents HD21 and HD22. Previously national standard bodies, such as the BSI, had freedom to issue their own national technically equivalent standards. Now, the new EN format must be implemented unchanged. The British Standards Institute therefore published all 18 parts of BS EN 50525.

One impact of this will be that 6491X and 6491B currently manufactured and tested to BS 6004 and BS 7211 are now excluded from those British Standards and are now be covered by EN 50525.

6491X: Previously BS 6004 Now manufactured to BS EN 50525-2-31:2011

6491B: Previously BS 7211 Now manufactured to BS EN 50525-3-41:2011. 90 °C cross linked

A number of cables with UK CMA codes and harmonised references will now be covered by the BS as shown in the table below:
