Thermal insulating products for building applications -

Determination of behaviour under point load

1 Scope

This Standard specifies equipment and procedures for determining the

behaviour of products under a force applied to a small area of a test specimen

at a given speed. This Standard is applicable to thermal insulating products.

This Standard can be used to determine whether the products have sufficient

strength to withstand the forces applied directly to them either during installation

or during application, mainly caused by pedestrian traffic.

NOTE The test methods given in the main body of this Standard and in Annex A are reported

and interpreted in different ways. The similarities that exist between the methods are not

sufficient to permit reasonable comparisons to be made.
