BS EN ISO 12162:2009

This standard BS EN ISO 12162:2009 Thermoplastics materials for pipes and fittings for pressure applications. Classification, designation and design coefficient is classified in these ICS categories:

• 23.040.20 Plastics pipes
• 23.040.45 Plastics fittings

This International Standard establishes the classification of thermoplastics materials in pipe form and specifies the material designation. It also specifies a method for calculating the design stress.

It is applicable to materials intended for pipes and fittings for pressure applications.

NOTE 1 Classification, minimum design coefficient and calculation method are based on the resistance to internal pressure with water at 20 °C for 50 years, derived by extrapolation using the method given in ISO 9080.

NOTE 2 Design coefficients for multilayer pipes are described in the appropriate product (system) standards.
