CALEDONIAN GUIDE TO CHANGES FOR NEWLY PUBLISHED EN 50525
European harmonized cable standards HD21 series and HD 22 series will be completely replaced by the new released EN 50525 series in January, 2014. The new EN 50525 series updates its requirements and arrangement. The relationship between EN 50525 series and HD21, HD 22 series can be found in the following table.Part number of EN 50525 |

BSI has published BS EN 50525-1:2011, Electric cables. Low voltage energy cables of rated voltages up to and including 450/750 V, which is the British Standard equivalent of EN 50525-1:2011. BS EN 50525-1:2011 was published on 30 September 2011 and replaces numerous British Standards (BS 638-4:1996, BS 7211:1998, BS 6004:2000, BS 6007:2006, BS 6500:2000 and BS 7919:2001, though BS 638-4:1996, BS 6007:2006, BS 6500:2000 and BS 7919:2001 remain current, and the new standard only partially replaces BS 6004:2000 and BS 7211:1998).
At the end of 2012 a number of changes to British Standards will come into effect.
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 Some existing British Standards featuring HAR products will be withdrawn on 31st December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British Standards being withdrawn on 31st December 2012.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.
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: |

6491B: |

Now manufactured to BS EN 50525-3-41:2011. 90 °C cross linked |
A number of cables with UK CMA codes and harmonized references will now be covered by the BS as shown in the table below:

BS 6500 and BS 7919 have now been replaced by the BS EN 50525 as detailed in the box below. It should be noted that in BS EN 50525-1 section 7.4 and annex A it describes tests and requirements to be met for the mechanical strength of flexible cables. These cables are required to be “halogen free”, the standard now clearly shows a procedure for assessment in BS EN 50525-1, 7.5 B.

Changes to BS 6004 and BS 7211
BS 6004 and BS 7211 were reissued in September 2012. 6491X and 6491B have now been removed from these standards and appear in BS EN 50525. BS 6004 and BS 7211 now cover only selected UK cables designs and will now include Arctic Flexible cords. The detail are in the table below:
