Guide to new British Standards

The introduction of BS EN 50525

  1. Some existing British Standards featuring HAR products will be withdrawn on 31st December 2012.
  2. BS EN 50525 for wiring and flexible cables up to and including 450/750 V was published in September 2011 and will become fully effective from 1st January 2013 and replaces a number of existing British Standards being withdrawn on 31st December 2012.
  3. There will be changes to existing standards BS 6004 and BS 7211 which were re issued in September 2012.

None of these amendments require changes to Prysmian manufacturing and market practice.

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.
