英文名称：Paper and board — Determination of air permeance (medium range) — Part 3: Bendtsen method

标准范围

该方法可确定中等范围内的空气渗透率。它适用于空气渗透率在0.35μm/（Pa·s）和15μm/（Pa·s）之间的纸张和纸板。不适用于粗糙表面的纸张和纸板，如皱纹纸和瓦楞纸，这些纸张和纸板不能牢固夹紧以避免泄漏。附录A考虑了Bendtsen测试仪的维护，附录B考虑了毛细管和可变面积流量计的校准。

The method determines air permeance in the medium range. It is applicable to papers and boards having air permeance between 0,35 μm/(Pa·s) und 15 μm/(Pa·s). It is unsuitable for rough surfaced papers and boards, such as creped and corrugated papers, which cannot be securely clamped to avoid leakage. Annex A considers maintenance of Bendtsen testers, Annex B calibration of capillary tubes and variable area flowmeters.
