A new standard to provide Corgi-registered gas installers with information they need to know about and apply to their work has just been published by the British Standards Institution (BSI).
Corgi-registered gas installers are continually re-assessed to ensure they are up-to-date with the latest changes in regulations. BS 6400-2:2006 provides the technical know-how to deliver comprehensive, safe and cost-efficient services to customers and communities across the UK.
BS 6400-2:2006 specifies requirements for the installation, exchange, relocation and removal of primary gas meters with a maximum capacity not exceeding 6 m³/h. It is applicable to installations that incorporate credit or prepayment diaphragm and electronic meters. Installation includes the design, inspection and commissioning which are often performed by the same person.
What does BS 6400-2 cover?
BS 6400-2 is applicable to primary meter installations:
- Supplied with 2nd family gases from medium pressure gas distribution systems operating with a maximum operating pressure exceeding 75 mbar but not exceeding 2 bar and with a design maximum incidental pressure of 2.7 bar
- Only fitted downstream of the emergency control valve
- That utilize a pressure control and protection system contained within a regulator-assembly that is downstream of the emergency control valve
- Where all gas fittings subjected to medium pressure have been pre assembled and where strength and gas tightness testing has been undertaken on the regulator assembly at the factory
- Where the operating pressure at the outlet of the meter is nominally 21 mbar.
BS 6400-2:2006 partially supersedes BS 6400:1997 which will be withdrawn when all 3 parts of BS 6400 have been published.
BS 6400 series of standards
- Part 1: Low pressure (2nd family gases)
- Part 2: Medium pressure (2nd family gases)
- Part 3: Low and medium pressure (3rd family gases)
