BSI BS ISO 14857:2014

Thermal performance in the built environment. Determination of air permeance of building materials

PUBLISH DATE 2014
PAGES 26
BSI BS ISO 14857:2014

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.
