DIN EN ISO 11507:2007适用范围

本国际标准规定了在包括荧光紫外灯和冷凝或水喷雾在内的仪器中暴露于人工风化的油漆涂层的暴露条件。通过所选参数的对比试验,分别评价了风化作用的影响。注:荧光灯产生的紫外线仅模拟自然阳光紫外线区域的一部分,因此,试样受到光谱的一小部分破坏。由于与太阳光相比,这种紫外线灯发出的光缺乏可见光和红外线能量,因此试件的加热方式没有达到实际使用时周围空气的温度以上。

This International Standard specifies exposure conditions for paint coatings exposed to artificial weathering in apparatus including fluorescent UV lamps and condensation or water spray. The effects of weathering are evaluated separately by comparative testing of chosen parameters. NOTE The ultraviolet light produced by fluorescent lamps simulates only part of the UV region of natural sunlight and, consequently, the test pieces are subjected to a small but destructive portion of the spectrum. Due to the lack of visible and infra-red energy in the light from such UV lamps compared to sunlight, the test pieces are not heated above the temperature of the surrounding air in the way in which they would be in practical use.
