ISO Grey Scales. For assessment of change in colour and staining in colourfastness testing 1-5 steps with half steps, in wallet.
ISO 标准灰卡/SDC标准评级灰卡,变色/沾色
Grey Scale for Change in Colour :
The grey scale consists of nine pairs of non-glossy neutral grey coloured chips which illustrate the perceived colour differences. These give a corresponding fastness rating of 5, 4-5, 4, 3-4, 3, 2-3, 2, 1-2, and 1.
They are used in the assessment of colour change occurring in fastness tests as described in ISO 105-A02.
They are also essential in the grading of light fastness tests when using the light fastness standards.
Grey Scale for Staining :
The grey scale consists of nine pairs of non-glossy grey and white coloured chips which illustrate the perceived depth of staining.
They give a corresponding fastness rating of
5, 4-5, 4, 3-4, 3, 2-3, 2, 1-2, and 1.
They are used to assess the amount of staining occurring on adjacent undyed fabrics during fastness tests. Their use is described in ISO 105-A03.
ISO 标准灰卡，用于评估色牢度测试中的变色、沾色，分1~5级，半级递增，装于包装套内。
变色灰卡：
该灰卡由九对无光的中性灰色小片组成，显示可分辨的色差。提供对应的牢度等级，即5、4-5、4、3-4、3、2-3、2、1-2和1。
它用于对ISO105-A02所描述的色牢度测试中发生的变色进行评估。
其在运用光牢度标准对光牢度测试进行分级时也很重要。
沾色灰卡：
该灰卡由九对无光的白色小片组成，显示可分辨的染色深度。提供对应的牢度等级，即5、4-5、4、3-4、3、2-3、2、1-2和1。
它用于评估牢度测试期间发生的贴衬未染色织物上的染色的总量。
其使用方法在ISO105-A03中有描述。
