DIN EN ISO 483-2006 塑料.为保持恒定湿度使用水溶液进行调节和试验用的小型密封容器(ISO 483-2005).德文版本 EN ISO 483-2005
Plastics - Small enclosures for conditioning and testing using aqueous solutions to maintain the humidity at a constant value (ISO 483:2005); English version of DIN EN ISO 483:2006-02
The document establishes guidelines for the construction and use of enclosures with volumes less than 200 dm3, in order to obtain atmospheres of constant relative humidity at given temperatures, using saturated aqueous salt solutions, glycerol/water solutions of 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.#,,#
