DIN EN ISO 11507:2007適用范圍

本國際標準規(guī)定了在包括熒光紫外燈和冷凝或水噴霧在內的儀器中暴露于人工風化的油漆涂層的暴露條件。通過所選參數的對比試驗，分別評價了風化作用的影響。注：熒光燈產生的紫外線僅模擬自然陽光紫外線區(qū)域的一部分，因此，試樣受到光譜的一小部分破壞。由于與太陽光相比，這種紫外線燈發(fā)出的光缺乏可見光和紅外線能量，因此試件的加熱方式沒有達到實際使用時周圍空氣的溫度以上。

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.

1 Scope

This International Standard specifies exposure conditions for paint coatings exposed to artificial weathering inapparatus including fluorescent UV lamps and condensation or water spray. The effects of weathering areevaluated 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 testpieces are not heated above the temperature of the surrounding air in the way in which they would be inpractical use.
