Commissioning of gas-fired plant on industrial and commercial premises

scope:

This Standard covers the commissioning of new and existing gas-fired plant and ancillary equipment designed for use on lighter and heavier than air flammable fuel gases such as Manufactured Gas, Natural Gas (NG), Liquefied Petroleum Gas (LPG), Biogas (including Biomethane) and LPG air mixtures.

Note 1: Typically a 1st family gas is manufactured, for example Towns Gas, a 2nd family gas is methane based, for example NG and a 3rd family gas is propane/butane based, for example LPG.

Note 2: LPG is primarily distributed in a gaseous form; however it can also be partially distributed in a liquid phase.

Note 3: 1st, 2nd and 3rd family gases are further defined in BS EN 437.

When working with 3rd family gases further advice on supply and use may be obtained from UKLPG.

In particular, UKLPG CoP 9 deals with LPG air plant and UKLPG CoP 17 deals with the purging of LPG vessels and systems.

This Standard is not retrospective, however it is recommended that this Standard also applies to existing plant which has been refitted, refurbished, modified, repaired or serviced and in any circumstance where recommissioning of plant is deemed necessary.

Note: In many cases for existing plant full commissioning procedures will need to be carried out. However, a shortened procedure may be appropriate at the discretion of the responsible engineer when the work involved has been of a minor nature.

This Standard promotes the adoption of sound, basic commissioning procedures for gas-fired plant and ancillary equipment. The Standard is intended to be used as guidance for the writing of specialised commissioning instructions for the whole or individual parts of particular plant and as a framework for the planning of commissioning of such plant. It is not intended in itself to constitute a commissioning procedure for any specific item of plant.

Any person involved in the commissioning of gas-fired plant is required to be competent in the appropriate disciplines. Competency is achieved by an appropriate combination of education, training and practical experience.

This Standard assumes general compliance with other Standards as appropriate, such as IGEM/UP/2, IGEM/UP/6, IGEM/UP/10, IGEM/UP/12, IGEM/UP/16, UKLPG CoP 1, UKLPG CoP 22, BS 5885 (partially replaced by BS EN 676), BS 6230, BS 6644, BS 6880, BS EN 676, BS 746, BS EN 12828 and BS EN 12953 etc. Reference needs to also be made to relevant plant and equipment manufacturers' instructions and commissioning check lists.

This Standard applies to the commissioning of gas-fired plant installed on industrial and commercial premises. It may equally be applied to large domestic premises that contain complex items of plant.

This Standard does not embrace the design of plant and therefore is written upon the assumption that plant and associated components are fit for the intended purpose and conform to appropriate Legislation, Standards and requirements of manufacture, installation and subsequent operation.

Certain items of gas-fired plant are specialised; hence certain commissioning actions will not be covered by this Standard. Additional reference will need to be made to the appropriate manufacturers' literature in such cases.

Pressures quoted are gauge pressures unless otherwise stated.

All heat inputs are net heat inputs unless otherwise stated.

Italicised text is informative and does not represent formal requirements.

Appendices are informative and do not represent formal requirements unless specifically referenced in the main sections via the prescriptive terms "must", "shall" or "should".
