“Three new editions of the Approved Documents (AD) for building in England have been released. ADs K and P will take effect on 6 April 2013, with AD 7 coming into force on 1 July 2013.
AD K (Protection from falling collision and impact) has been updated to amalgamate AD N (Glazing), as well as some overlapping guidance included in AD M (Access to and use of buildings). As well as these changes, references have been updated in the light of the harmonised standard related to ‘safe breaking’ and testing methods, and the harmonised standard and National Annex related to resistance of loads for barriers. Tables and diagrams have been amended and simplified, key terms have been updated, and there is now an index. There are no new technical requirements.”
