标准范围

本文件规定了一种试验方法，旨在确定用作汽车内饰材料的橡胶或塑料涂层织物的雾化特性。该方法也适用于流体、糊状、粉末或固体原料，这些原料是此类装饰材料的基础，或用于制造材料。该方法也适用于其他材料和成品。本程序适用于在试验条件范围内测量玻璃表面上的雾冷凝液。本测试无法准确测量以下情况:-？冷凝液的表面张力低，导致早期聚结成一层透明薄膜；-？冷凝液的数量如此之大，以至于液滴聚结并形成一层厚重的油膜/透明膜（这层厚重的膜给出了错误的读数）。在这种情况下，最好采用重量分析法。

This document specifies a test method which is intended to determine the fogging characteristics of rubber- or plastics-coated fabrics that are used as trim materials in the interior of motor vehicles.

The method can also apply to fluid, pasty, powdered or solid raw materials which are the basis for such trim materials or from which the materials are manufactured. The method can also apply to other materials and finished products.

The procedure is applicable to the measurement of fog condensate on glass surfaces within the limits of the test conditions. This test cannot measure accurately those cases in which:

—    the surface tension of the condensate is low, resulting in early coalescing into a thin transparent film;

—    the condensate is present in such a large quantity that the droplets coalesce and form a heavy oily/clear film (this heavy film gives false readings).

In such cases, the gravimetric method is preferred.
