Thermal performance in the built environment. Determination of air permeance of building materials Ingestion-build-156411 Why should you use BS1 Scope 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 (P) of 75 Pa. This method is intended for testing materials independent of a substrate using a 1 m 1 m specimen size. The results of this test method can be used to determine whether a material qualifies to
