ASTM C1338 - 14 Standard Test Method for Determining Fungi Resistance of Insulation Materials and Facings

Description of Standard

Significance and Use

2.1 The type of materials used in the manufacture of insulation products and the type of membrane used to face these products can sometimes affect fungi sustenance in the presence of high humidity.

2.2 This test method is used to determine the relative ability of an insulation and its facing to resist fungal growth under conditions favorable for their development.

2.3 This test method uses a comparative material to determine the relative ability of a material to resist fungal growth. In some specialized product areas, it is required that no growth take place. In such cases, the use of the comparative material is omitted and the pass/fail criterion is based upon growth.

1. Scope

1.1 This test method covers the determination of the ability of new insulation materials and their facings to resist fungal growth.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
