Document History

Collectively parts 1 to 5 of BS EN 1452 supersede BS 3505:1986, BS 4346-1:1969 and BS 4346-2:1970. Since those British Standards are the basis of piping systems with a design life of at least 50 years, it is intended that they will be declared obsolescent by 26/6/2001. These parts also partially supersede BS 4346-3:1982. BS EN 1452-4:1999 (previously dated as BS EN 1452-4:2000) also covers PVC-u valves and tapping saddles, for which there were no previous British Standards. A dynamic endurance test is also included. AMD 11013 is Corrigendum No.1. dated July 2000 - Indicated by a sideline. AMD 12007 is Corrigendum No.2. dated October 2000 - Correction to National foreword supersession details. Amendment dated 31 August 2009 - Correction to National foreword supersession details, and alignment of BSI and CEN publication dates. Amendment dated 31 October 2009 - Correction to Table 1. Superseded by BS EN ISO 1452-4:2009.
