BS 5608 specifies the composition, physical properties, and dimensional tolerances for preformed rigid polyurethane (PUR) and polyisocyanurate (PIR) foams for the thermal insulation of pipework and equipment. BS 5608 applies to slabs, cut and molded pipe sections, and radiused and beveled lags. The nominal temperature range for which the insulation material is suitable is – 180 °C to + 140 °C (see Annex F).
