标准摘要
[中文适用范围]： ISO 5636 的这一部分规定了使用 Bendtsen 装置测定纸和纸板透气度的 Bendtsen 方法。 它适用于用Bendtsen仪器测试时透气度在0.35μm/(Pa·s)和15μm/(Pa·s)之间的纸和纸板。 不适合表面粗糙的材料，不能牢固夹紧以避免泄漏。 [外文原描述]： ISO 5636-3:2013 specifies the Bendtsen method for determining the air permeance of paper and board using the Bendtsen apparatus. It is applicable to papers and boards which have air permeances between 0,35 µm/(Pa·s) and 15 µm/(Pa·s) when tested with the Bendtsen apparatus. It is unsuitable for rough-surfaced materials which cannot be securely clamped to avoid leakage.
