BS EN ISO 22282-2:2012 BRITISH STANDARD National foreword This British Standard is the UK implementation of EN ISO 22282-2:2012. Together with parts I, 3, 4, 5, and 6 of BS EN IsO 22282, it partially supersedes BS 5930:1999+A2:2010, which is currently being revised in order to remove conflicting material.

The test given in this standard is included in BS 5930:1999+A2:2010 (Clause 25.4), and conflicting parts are now withdrawn.
