ISO 5636-4:2013规定了使用谢菲尔德仪器测定纸张和纸板透气性的谢菲尔德方法。
本标准适用于使用谢菲尔德仪器测试时,空气渗透率在0.02μm/(Pa·s)和25μm/(Pa·s)之间的纸张和纸板。
不适用于表面粗糙的材料,这些材料无法牢固夹紧以避免泄漏。
ISO 5636-4:2013 specifies the Sheffield method for determining the air permeance of paper and board using the Sheffield apparatus.
It is applicable to papers and boards which have air permeances between 0,02 μm/(Pa·s) and 25 μm/(Pa·s) when tested with the Sheffield apparatus.
It is unsuitable for rough-surfaced materials, which cannot be securely clamped to avoid leakage.
