标准摘要
[中文适用范围]： 本国际标准制定了体积小于 200 dm3 的外壳的构造和使用指南，以便使用饱和盐水溶液、甘油/水溶液或硫酸/水溶液在给定温度下获得恒定相对湿度的气氛，以用于调节和测试塑料。 它规定了在特定国际标准规定的温度下将调节和测试气氛的相对湿度保持在所需公差范围内所遵循的程序。 所描述的程序旨在用于在测试之前调节少量材料，以及可以完全在小外壳内进行的测试，例如电气测试。 所述指南不适用于需要频繁打开的外壳。 [外文原描述]： ISO 483:2005 establishes guidelines for the construction and use of enclosures with volumes less than 200 dm 3 , in order to obtain atmospheres of constant relative humidity at given temperatures, using saturated aqueous salt solutions, glycerol/water solutions or sulfuric acid/water solutions, for conditioning and testing plastics. It specifies the procedures to be followed to maintain the relative humidities of the conditioning and testing atmospheres within the required tolerances, at the temperatures specified by particular International Standards. The procedures described are intended for conditioning small quantities of materials prior to test, and for such tests as may be carried out entirely within a small enclosure, e.g. electrical tests. The guidelines described do not apply to enclosures requiring frequent opening.
