Describes the equipment and procedures to determine the air permeance of building materials at various pressure differentials and then assigning an air permeance rate at a reference pressure differential rate (Delta P) of 75 Pa.

This International Standard specifies the equipment and procedures to determine the air permeance of building materials at various pressure differentials and then assigning an air permeance rate at a reference pressure differential rate (ΔP) of 75Pa.

This method is intended for testing materials independent of a substrate using a 1m×1m specimen size. The results of this test method can be used to determine whether a material qualifies to function as an air barrier material.
