Thermal insulation products. Assessment of the susceptibility to mould growth. Laboratory test method. | Status: Current

1 Scope This document describes a laboratory test method to determine the susceptibility of thermal insulation products used for construction against mould growth under specified climatic conditions. The method is applicable to both factory-made products and in situ formed products. Factory-made products include panels, mats and rolls.

NOTE In situ formed products are usually those that are delivered loose and installed by blowing-in, pouring, or spraying-on, eventually using water and/or binder, whether or not they are also treated using additives.

The test is carried out with one of the conditions described in Table 1. This test method determines the susceptibility of a thermal insulation material to mould growth, but it does not determine the suitability for use in a given design (wall, roof, etc.). This method does not predict the resistance of an insulation product to water damage.
