scope:

1.1 This test method is to determine the air leakage rate of building materials at various pressure differentials with the intent of calculating an assigned air permeance rate of the material at the reference pressure difference (δP) of 75 Pa.

1.2 The method is intended to assess flexible sheet or rigid panel-type materials using a 1 mx1 m specimen size.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurements are included in this standard.

1.4 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.

1.5 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.
