5.8 Resistance of plastic sheets to discolouration under the effect of moisture
The plastic sheets shall be exposed to weathering according to ISO 105 B04 for 24 ,Afterwards ,the sample shall be stored at standard at standard atmosphere according to ISO 554 for 24 .A possible discolouration shall be evaluated on the basis of the grey scale for the grey scale for the assessment of colour changes (according to ISO 105 – A02)
塑料板应依ISO 105 B04 for 24所规定， 暴露风化，然后，样品应依ISO 554 for 24 所规定贮存于标准空气中。可能的脱色应依据估量变色的灰度测试计所显示灰度来评估。
真是很拗口
