标准摘要
[中文适用范围]: 本国际标准规定了两种测定机动车辆乘客舱所用皮革起雾特性的替代方法,即方法A和方法B。 这是两种不同的测试程序,用于测量挥发性成分,结果之间不存在数学相关性。 方法 A 通过反射测定光散射特性(或不透明性)以及由冷凝在冷玻璃表面上的挥发性成分形成的薄膜或液滴的性质。 方法 B 通过重量分析法测量冷铝箔表面凝结的挥发性成分的数量。 附录 A 给出了实验室间试验的结果,表明方法 B 表现良好,而方法 A 的反射百分比差异较大。 测试条件允许两个测试连续进行。 [外文原描述]: ISO 17071:2006 specifies two alternative methods for determining the fogging characteristics of leathers used in the passenger compartments of motor vehicles, namely Method A and Method B. These are two different test procedures to measure the volatile components and there is no mathematical correlation between the results obtained with Method A and those with Method B. Method A determines by reflection the light scattering properties (or opaqueness) and the nature of the film or droplet formation from volatile components condensed on a cold glass surface. Method B measures gravimetrically the quantity of volatile components condensed on a cold aluminium foil surface. Annex A gives the results of inter-laboratory trial which show that Method B performs well, whereas Method A showed a large variation in the percentage reflection. The test conditions allow the two tests to be carried out in succession.
