    • An environmental cabinet is described for simulating the effects of extended outdoor weathering on a sample material, the outdoor weathering effects including subjecting the sample material to cycles of at least the application of a corrosive solution and exposure to electromagnetic radiation. The cabinet comprises a chamber (11) for containing a sample material to be tested and a source (55) of electromagnetic radiation for subjecting the sample material within the chamber to cycles of radiation. Spray device (19) provides a cyclic spray of a corrosive solution to be deposited on the sample material within the chamber. Control unit subjects the sample material within the chamber to electromagnetic radiation and corrosive solution in a cyclic manner. The source (55) of electromagnetic radiation is disposed within a radiation transparent shield (57) passing through and sealed to the chamber.
    • 描述了一种环境柜,用于模拟室外长时间风化对样品材料的影响,室外风化作用包括使样品材料至少施加腐蚀性溶液和暴露于电磁辐射的循环。 机柜包括用于容纳要测试的样品材料的室(11)和用于使室内的样品材料经受辐射循环的电磁辐射源(55)。 喷雾装置(19)提供要沉积在室内的样品材料上的腐蚀性溶液的循环喷雾。 控制单元以循环方式对室内的样品进行电磁辐射和腐蚀性溶液。 电磁辐射源(55)设置在通过并密封到腔室的辐射透明屏蔽(57)内。
