Product standards used in the Gas Valves and Regulators Industry are technical specifications and guidelines that define the characteristics of a product to ensure quality, safety and performance. They are used to ensure products meet minimum safety requirements and are fit for their intended purpose.

The Standards are developed by governmental regulatory bodies and industry organisations, and are essential for promoting sustainability and environmental responsibility.

There are ISO (International Standards Organisation), CEN (European Committee for Standardization) and national versions.

Standards are not Laws but are often referenced in Laws and in conventions/agreements such as ADR, so all manufacturers are required to produce products to those Standards, so they are in conformance with local and international law.

 GVARA engages with the ISO Standards body using its approved liaison status and also has representation on European, CEN (European Committee for Standardisation)  and other National Standard bodies such as BSI (British Standards Institute) and DIN (German Institute for National Standardisation).

The main ISO Standards established for the Valves and Regulators referenced and followed by GVARA Members are shown below:

Industrial and Speciality Gas Valves: ISO 10297, ISO 15996 and ISO 22435 

Industrial and Speciality Gas Regulators: ISO 2503, and  ISO 7291

Medical Valves: ISO 10524-1,10524-2

Medical Regulators: ISO 10524-3

Gauges: ISO 5171
