CEN/TC 326/WG 3 - NGV Operations
This WG provides requirements for the operation ("user manual") of vehicles using CNG (natural gas or biomethane) as fuel, giving recommendations of good, safe and environmental friendly practice for users, including transit through specific areas (tunnels, ferries, etc.), fuelling, parking, and workshops, and also giving instructions in case of accident.

CEN/TC 326/WG 3 develops CEN standards. The scope of work includes: This WG provides requirements for the operation ("user manual") of vehicles using CNG (natural gas or biomethane) as fuel, giving recommendations of good, safe and environmental friendly practice for users, including transit through specific areas (tunnels, ferries, etc.), fuelling, parking, and workshops, and also giving instructions in case of accident. Currently, there are 2 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This document provides requirements for operation of vehicles that use compressed natural gas (CNG) as a fuel for propulsion, covering various aspects of NGV workshops including activities, risk management, planning, personnel, layout, systems and operations. It provides requirements regarding the management of NGVs including use, parking, fuelling for commissioning, inspection, installation, repair and maintenance, disposal, transportation and documentation.
This document is applicable to the management of CNG vehicles with a fuel system pressure of 20 MPa (200 bar) at 15 °C. This document can also be applied to vehicles with higher fuel system pressures, taking into account additional safety aspects.
This document also applies to servicing, repair and maintenance of NGVs when work is not performed on the gas fuel system.

1.1 This Standard gives recommendations for the operation of vehicles fuelled with natural gas and operating at a fuel system pressure not exceeding 20MPa (200 bar) at 15°C. 1.2 This standard may be applied to higher system pressures, but due regard should then be given to safety aspects such as, ventilation rates, hazardous area requirements and other aspects associated with those higher pressures.
