History

Superseded by BS EN 1365-1, BS EN 1365-2, BS EN 1365-3, and BS EN 1365-4, but remains current until 2 September 2029. Supersedes BS 476-8:1972. Confirmed June 2016. Amendment C1 dated April 2014 - Information added to Foreword. Amendment C2 dated December 2024 - Supersession updated in Foreword. This standard has been superseded by the current BS EN 1365-1, BS EN 1365-2, BS EN 1365-3 and BS EN 1365-4, but it has been retained based on legitimate need for the standards within non-EU markets.
