ISO 5636-5:2013
Paper and board -- Determination of air permeance (medium range) -- Part 5: Gurley method
Product Details
It is applicable to papers and boards which have air permeances between 0,1 µm/(Pa⋅s) and 100 µm/(Pa⋅s) when tested with the Gurley apparatus.
It is unsuitable for rough-surfaced materials, which cannot be securely clamped to avoid leakage.
ISO 5636-5:2013 may also be used to determine the air resistance of paper and board.
