Thermal insulating products for building applications — Conditioning to moisture equilibrium under s...
This International Standard specifies equipment and procedures to condition a thermal insulating product to equilibrium moisture content at (23 ± 2) °C and (50 ± 5) % relative humidity.
It is also applicable to thermal insulating products with moulded skins but is not normally relevant for faced products or for products with other surface treatments.
NOTE 1 The normally specified moisture content…
Thermal insulating products for building applications — Determination of shear behaviour
This International Standard specifies the equipment and procedures for determining shear behaviour. It is applicable to thermal insulating products.
NOTE The tests described in this International Standard do not determine pure shear behaviour, but measure the effects of applying two opposite parallel forces to the major faces of the test specimen. The test is, however, called "shear" in…
Thermal insulating products for building applications — Determination of freeze-thaw resistance
This International Standard specifies the equipment and procedures for determining the effects of successive cycling from dry conditions at −20 °C to wet conditions at 20 °C on the mechanical properties and moisture content of the product. It is applicable to thermal insulating products.
It is intended to simulate freeze?thaw effects on thermal insulating products which are frequently exposed to…
