BS EN 1916 and BS EN 1917 [see Pipes and drainage (BS EN)] are running in parallel with BS 5911, which they will eventually replace. Note that some parts of BS 5911 have not yet been covered by an equivalent BS EN. In the meantime some parts of BS 5911 are being renumbered and reissued (e.g. BS 5911 Part 230 was replaced by BS 5911 Part 6 in 2004).
