1.1 This method provides a qualitative measure of the corrosiveness of mineral-fiber or cellulose fiber insulation by comparison to a control.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The fiber composition and the type of binder used in the manufacture of mineral fiber insulation can sometimes create a potential for corrosion on certain metals in the presence of water or water vapor.

5.2 The fiber composition and type of fire retardant used in the manufacture of cellulosic fiber insulation can sometimes create a potential for corrosion on certain metals in the presence of water or water vapor.

5.3 This method is used to determine the relative corrosion potential of mineral or cellulosic fiber insulation on specific metals under elevated temperature and high humidity conditions only.
