BS ISO 17467-3:2012

This standard BS ISO 17467-3:2012 Plastics piping systems for the supply of gaseous fuels. Unplasticized polyamide (PA-U) piping systems jointed by solvent cement is classified in these ICS categories:

• 23.040.20 Plastics pipes
• 23.040.45 Plastics fittings

This part of ISO 17467 specifies the physical and mechanical characteristics of fittings made from unplasticized polyamide (PA-U) in accordance with ISO 17467-1, intended to be buried and used for the supply of gaseous fuels for maximum operating pressure up to and including 4 bar.

It also specifies the test parameters for the test methods to which it refers.

This part of ISO 17467 also lays down requirements for dimensions and the marking of fittings.

In conjunction with ISO 17467-1 and ISO 17467-2, this part of ISO 17467 is applicable to PA-U fittings, their joints and to joints with components of PA-U.

These fittings can be of the following types

• solvent cement socket fittings;

• solvent cement spigot fittings;

• solvent cement saddle fittings.
