Specfies basic requirements for apperatus and general operating procedures for determining the air permeance of paper and board in the medium air permeance range, and is applicable to papers and boards having air permeances between 1 x 10- and 1 x 10 m/(Pa.s), being unsuitable for rough-surface papers such as creped and corrugared papers, which cannot be securely clamped to avoid leakage.
