I've been speaking with the BRE this week who have stated that the EU are not currently willing to harmonise this standard in it's current form. Therefore if the date currently reported on the FPA site is to be maintained then the UK would be going it alone.
BRE have asked the BSI to confirm what is proposed with respect to any planning change-over date.
The normal procedure would be that the EN would come into force 3 years after it is published in the EU journal - as there is no intenetion to do this at the moment then there are no firm plans for it to become a harmonised European Standard.
The LPC rules give a comparison between the BS and the BSEN.
I have come across a conflict with the BSEN in relation to protection for Shopping Centres.
Clothing has been increased in category from 1 to 2/3. This then requires high hazard protection, particularly in storage areas, for shop units to utlise the full volume of their unit to the maximum. However, the BSEN does not allow hazards greater than OH3 to be zoned - required for life safety installations.
It would appear that the water supply to life safety systems has actually been downgraded from duplicate supply to superior supply!
Any other queries then let me know. It would appear that there a few people that have really got there head inside this document due to the uncertainty of its introduction.
