BSS Checks Amended to accept new EU Gas Hose Standard

The BSS checks have changed with immediate effect as the BSS requirements now recognise two new classes of hose following the recent publication of a new European LPG hose standard.

Class 3, and where appropriate Class 2 hose, from BS EN 16436‐1:2014, Rubber and plastics hoses, tubing and assemblies for use with propane and butane and their mixture in the vapour phase Part 1: Hoses and tubings, are now included as compliance options within BSS the private craft checks 7.7.3R; 7.9.1R & 8.6.1R.

The new additions also apply to the 2002 BSS Standards for non‐private craft, which sees the relevant checks, C7.10.4; C7.13.1 & C8.2.2f amended.

The BSS is urging boaters, fitters, chandlers and other suppliers, to check carefully before hose marked to BS EN 16436 is selected as there needs to be a clear understanding of which class of hose is suited to which part of the gas system. The BS EN 16436 Class 2 hose is unsuitable for the high‐pressure side of propane systems because of its potential to burst if the LPG cylinder is subject to extreme summer temperatures, such as the conditions that could be created when a boat is covered up.

Accordingly if hose marked to the new standard is installed on the high‐pressure side of any LPG system, the BSS will only accept that showing as Class 3.

On the low‐pressure (supply) side for propane, or butane, we can accept BS EN 16436 Class 2 or EN 16436 Class 3 hose.

The BSS wants to make it clear that it will continue to accept hose marked to BS 3212 Type 2 as long as the hose remains in good condition. It believes that manufacturers will continue to mark their LPG hose products to BS 3212 Type 2 until the standard is withdrawn by British Standards Institute (BSI) and that may not happen for some time.
