Unplasticized poly(vinyl chloride) alloy (PVC-A) pipes and bends for water under pressure
This Product Assessment Specification specifies the requirements for unplasticized poly(vinyl chloride)-based plastics alloy (PVC-A) pipes, and PVC-A post-formed bends with integral joints, intended for the conveyance of drinking water under pressure.
The pipes are intended for use below ground, and also above ground provided they are not exposed to direct sunlight.
The pipes are suitable for service temperatures between 0 °C and 40 °C.
NOTE 1: At temperatures above 20 °C, pressure derating is necessary and should be in accordance with guidelines provided by the manufacturer.
NOTE 2: If it is intended to use pipes conforming to this specification for the conveyance of fluids other than water, the manufacturer should be consulted.
NOTE 3: For any application involving surge and fatigue, reference should be made to the relevant UK Water Industry Information and Guidance Note [1]. For drinking water, the recommended temperature for rerating is 10 °C, whereas for other fluids higher temperatures may be appropriate.
NOTE 4: PVC-A pressure pipes conforming to this specification, and associated fittings, should be installed and used in accordance with the manufacturer's recommendations.
To assist arrangements for quality control or assessment of conformity, annex A gives a classification for assigning each requirement and associated test to quality control or type test purposes respectively.
