scope:

This Standard covers industry agreed changes to working practice set out in IGEM Communication 1830 and covers:

• limit on the nominal gas load for domestic premises in kW

• harmonise procedures for installing appliances covering:

• pre-commissioning

• commissioning

• post commissioning.

• conditions for reporting low pressure supply

• method of testing for low pressure on the installation

• response from the emergency service providers.

This Standard essentially covers domestic supply capacity and the operating pressure at the outlet of the meter. These changes in some of the details conflict with current published BSI standards and established company procedures. The industry is arranging to have such information updated in line with this Standard in due course.

All pressures quoted are gauge pressures, unless otherwise stated.
