All IGEM Technical Gas Standards

This standard sets out industry best practice for managing works that take place near gas assets and associated installations. It ensures the continued integrity, safety, and protection of gas infrastructure when third-party or internal works are carried out in their vicinity.

This standard summarises best practice for the design, installation, operation, inspection, maintenance and decommissioning of Vacuum Insulated Tanks (VITs) for LNG service. It combines well established practices with new advice on aspects of design and construction of such installations.

This technical standard sets out the requirements for training in gas work, in line with the Health and Safety at Work Act and the Gas Safety (Installation and Use) Regulations (GS(I&U)R).

This standard contains basic guidance on the transport and storage of polyethylene (PE) pipes and fittings for use in any fuel gas installation.

This standard provides guidance on gas installations in buildings designed to be used by multiple sets of occupants, whether as a home or as a commercial property i.e. a set of flats above a shop.

This Standard sets down the minimum management requirements for the laying of newly constructed natural gas mains and services, including associated installations. For example, a pressure regulating installation having a maximum operating pressure of 7 bar, for adoption by a gas transporter. Their use is intended primarily for Great Britain, although the principles may be applied in other countries.

Fourth edition of IGEM/UP/1B now available to buy. The IGEM/UP/1B standard contains information on the testing and purging of pipework found in small gas installations.

This standard details what actions should be taken in the event of a Natural Gas leak from either piped supplies or systems.

This standard defines various important terms within natural gas systems and provides a basic guide to the arrangement of the components required in such a system.

The IGEM/G/11 standard provides a procedure for the gas industry to identify, classify, and report unsafe gas situations.

This standard covers the safe installation of pipework on industrial and commercial premises.

This Specification is part of a series of Institution of Gas Engineers and Managers (IGEM) publications, providing a specification for selecting meter installation fittings.

This standard gives requirements for design, construction, inspection, testing, operation and maintenance of steel and polyethylene (PE) pipelines for gas distribution.

The IGEM/TD/4 standard contains details of basic pipeline construction, installation and maintenance for gas services

This standard covers purging operations for fuel gases in transmission, distribution and storage.

his Standard covers gas utilization activities associated with the design, installation, commissioning, and maintenance of low-pressure Hydrogen gas installations, downstream of the Emergency Control Valve (ECV), in domestic premises, forming part of a UK Government-approved coordinated community-based trial.

This Standard covers gas utilisation activities associated with the design, installation, commissioning, and maintenance of Hydrogen gas installations, downstream of the Emergency Control Valve (ECV), in non-domestic premises, forming part of a UK Government approved coordinated community-based trial.

This Reference Standard aims to identify and discuss the principles required for the safety and integrity of Hydrogen installation and utilisation in premises.

This standard contains guidelines for analysing and managing the risks presented by buried natural gas pipelines.

This Guide supersedes IGEM/IG/2 Edition 1.  It has been drafted by a Panel appointed by the Institution of Gas Engineers & Managers’ (IGEM’s) Gas Utilisation Committee , subsequently approved by that Committee, approved by the Technical Coordinating Committee and published by the authority of the Council of the Institution. The current panel is chaired by Graham McKay.

This Standard has been produced primarily for the benefit of network designers, operators of caravan parks and marinas, and gas operatives, providing best practice on distributing, metering and installing Natural Gas (NG) and liquefied petroleum gas (LPG) (including cylinder and bulk storage) plant, along with additional requirements, interpretation and clarification of national legislation, standards and Codes of Practice (CoPs).

This guidance provides a framework that allows businesses to demonstrate they are adequately qualified for their role in the gas industry

Synopsis of IGEM/TD/1 Edition 6 with amendments May 2024: This Standard supersedes Edition 6, Communication 1848, published in 2021. It has been approved by the Gas Transmission and Distribution Committee (GTDC) and published by the authority of the Council of IGEM.

IGEM/TD/13 Edition 2 Supplement 1 - Pressure regulating installations for hydrogen at pressures exceeding 7 bar

Pressure regulating installations (PRIs) for new and repurposing of existing PRIs for transmission of Natural Gas (NG)/Hydrogen blends for pressures not exceeding 7 bar

This Standard covers the product requirements for primary diaphragm gas meters with a maximum flow rate in the range 6 m³h-1 to 160 m³h-1 that may be purchased for installation in domestic, commercial and industrial locations.

This Reference Standard is aligned to IGEM/TD/13 Edition 3 and aims to identify and discuss the principles required for the safety and integrity of Hydrogen pressure regulating.

This standard covers the minimum safety requirements for combustion systems used in gas fired commercial plant

This Reference Standard addresses the issues arising from the proposal to distribute Hydrogen through existing NG steel and PE pipelines (mains and services) repurposed for Hydrogen service at pressures not exceeding 7 bar.

This standard provides guidance for emergency situations involving transportation by road of bulk LNG on public highways and s applicable to LNG transport in the United Kingdom.
