BS EN 1747-11 on measurement of air pollution is relevant to:

This standard specifies the ranges of environmental conditions for operation of the filters

(2) Eurocode 4 is concerned only with requirements for resistance

BS 3568 lays out the provision for the test method that helps you verify the properties and amount of the soluble contents in the wool

Paper and board. Determination of air permeance (medium range) - Gurley method Ingestion-build-132972 and preparation of specimens1 Scope This part of ISO 5636 specifies the Gurley method for determining the air permeance of paper and board using an air resistance tester, the Gurley apparatus. It is applicable to papers and boards which have air permeances between 0,1 m (Pas) and 100 m (Pas) when tested with the Gurley apparatus. It is unsuitable for rough surfaced materials, which cannot be securely clamped to avoid leakage. This part of ISO 5636 may also be used to determine
