Quality Assurance All products manufactured by Hepworth have to pass our stringent quality control procedures. A substantial majority also satisfy continuous assessment schemes operated by the British Standards Institution and are entitled to carry the Kitemark Products which bear a British Standard number have been made in accordance with the appropriate specification. Where no relevant British Standards exist products are manufactured to our own high standards. Application To provide an efficient means of drainage of waste water, to either a gully or soil stack, from single or multi-story buildings. Thermal Movement Coefficient of linear expansion 0.5 x 10 -4 /°C temperature rise. (See fixing instructions for further details). Effect of Solar Radiation The performance of ABS waste systems is unaffected by solar radiation. The painting of external pipework, however, is recommended to give protection against the discolouring effects of strong sunlight. Effect of Frost Frost does not have any long term detrimental effect on the pipe. However the impact strength can be reduced at sub-zero temperatures. Flammability Flammability = 1.3 inches per minute. Test method BS 2782 508A Effect of Chemicals ABS is resistant to most organic acids, alkalis and aqueous solutions although subject to attack by some inorganic acids and concentrates. Reaction with other Materials ABS has not been found to react adversely with any traditional building materials. Maintenance Designers should provide adequate access for periodic cleaning. It is advisable to paint pipes fixed externally for protection against the effect of strong sunlight. Prefabricated Items For installations that require special products, a prefabrication service is available. Information on these items is available through the Technical Services Department.
