DESCRIPTION
BS ISO 14857:2014
This standard BS ISO 14857:2014 Thermal performance in the built environment. Determination of air permeance of building materials is classified in these ICS categories:
- 91.120.10 Thermal insulation of buildings
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.
