What is this standard about?
It specifies the requirements and test methods associated with maintaining pressurised water supply pipelines.
Who is this standard for?
- Designers, manufacturers and suppliers of such pipelines
- Water engineers
- Water boards and local authorities
- Testers
- Health and safety/environmental specialists
Why should you use this standard?
The standard has been developed to ensure that test methods, conditions and apparatus simulate as closely as practical normal service conditions to determine that the products will deliver a minimum 50-year service life. The standard determines requirements for structural strength/integrity, joint capabilities, sealing properties, corrosion resistance, and end load restraint (where appropriate) plus materials.
It applies to fittings with flexible, flexible restrained and restrained joints for connection to existing water supply transmission and distribution pipes. These pipes are for the purposes of localized repair, new branch connections or pipeline rehabilitation. The standard also specifies requirements for materials and dimensions. It also gives performance requirements for joints.
The standard also specifies requirements for repair/renovation and connection fittings intended for use on existing water mains pipes such as repair couplings, flange adaptors, repair clamps/collars, encapsulation units and under pressure tees.
