This Part of BS 4508 specifies requirements for the design, materials, construction, installation, testing and fault monitoring of thermally insulated underground piping systems using a steel casing enclosing an insulated service pipe and incorporating an air gap, suitable for conveying fluids at temperatures exceeding 5 °C.
In addition to the definitive requirements given, it also requires the items detailed in clause 3 to be documented.
