ISO 17071:2006规定了两种测定汽车乘客舱中使用的皮革雾化特性的替代方法，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，方法A和方法B所得结果之间没有数学相关性。方法A通过反射确定光散射特性（或不透明性）以及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通过重量法测量冷凝在冷铝箔表面上的挥发性成分的数量。附录A给出了实验室间试验的结果，结果表明，方法B表现良好，而方法A显示反射百分比变化较大。试验条件允许连续进行两次试验。

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.
