ISO 1136:1976 羊毛 纤维平均直径的测定 透气性法

标准编号：ISO 1136:1976

中文名称：羊毛 纤维平均直径的测定 透气性法

英文名称：Wool — Determination of mean diameter of fibres — Air permeability method

发布日期：1976-11

标准范围

透气性测试方法基于Kozeny方程。称重后的纤维（试样）放入已知体积的测量室中。空气通过该试样。可以用流量或压差的适当绝对单位校准指示空气渗透性变化的刻度，并提供表格或图表，将观察到的读数转换为测量羊毛纤维的平均直径值。

The air permeability test method is based on the Kozeny equation. Weighed fibres (test specimen) are introduced in a measuring chamber with known volume. Air is passed through this test specimen. A scale indicating variations in permeability of air may be calibrated in appropriate absolute units of rate of flow or pressure difference and a table or graph is provided for conversion of the observed reading into values of mean diameter of the measured wool fibres.
