Thermal performance in the built environment – Determination of air permeance of building materials
Organization: | SNZ |

Page Count: | 24 |
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 (ΔP) 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 function as an air barrier material.
