Peter Mason of Blue Flame Associates Ltd reviews the significant proposed changes to BS 6891 – Specification for the installation and maintenance of low pressure gas installation pipework of up to 35mm (R1¼) in premises.

A revised British Standards Institution (BSI) standard, BS 6891:2013, is currently in the ‘draft for comment’ stage.
The revised standard is intended to replace BS 6891:2005, and the relevant parts of BS 5482–1:2005. The revised standard is intended for use by those involved in the design, installation, commissioning and maintenance of gas installation pipework (both natural gas (NG) and Liquefied Petroleum Gas (LPG)) up to 35mm or 1¼ inch steel pipework. The pipework may be installed in premises including residential park homes with a maximum flow rate of 16m3/h (a U16 or G10 gas meter).
