BS 7523:1991

This standard BS 7523:1991 Specification for preformed cellular polyethylene (PE) materials for the thermal insulation of pipework is classified in these ICS categories:

• 83.100 Cellular materials

This British Standard specifies the composition, properties and dimensional tolerances for preformed cellular polyethylene (PE) materials for the thermal insulation of pipework. The nominal operating temperature range for the materials is − 40 °C to + 80 °C (see note 1).

NOTE 1 Manufacturers have experienced no detrimental effects at service temperatures up to 100 °C. Consideration will be given, therefore, to raising the upper service temperature limit at the next revision of this British Standard.

NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.

Requirements for two types of polyethylene pipe insulation.
