EUROLAB laboratory provides testing and compliance services within the scope of ISO 4437 standard. ISO 4437 specifies the general properties of polyethylene (PE) compounds for the manufacture of pipes and fittings intended for use for the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in this International Standard.

In conjunction with ISO 4437-2, ISO 4437-3, ISO 4437-4 and ISO 4437-5 it applies to PE pipes, fittings and valves, their connections and connections intended to be joined with PE components and other materials.

It is used under the following conditions:

• Maximum working pressure (MOP) is based on design stress determined by dividing the composite minimum required strength (MRS) by a factor of C and considering rapid crack propagation (RCP) requirements;
• A temperature of 20 °C as the reference temperature for the design basis.

It is the responsibility of the buyer or the specifier to make the appropriate selections in these aspects, taking into account their specific requirements and relevant national regulations and installation practices or codes.
