ISO Grey Scales. For assessment of change in colour and staining in colourfastness testing 1-5 steps with half steps, in wallet.
ISO 標準灰卡/SDC標準評級灰卡,變色/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 標準灰卡，用于評估色牢度測試中的變色、沾色，分1~5級，半級遞增，裝于包裝套內。
變色灰卡：
該灰卡由九對無光的中性灰色小片組成，顯示可分辨的色差。提供對應的牢度等級，即5、4-5、4、3-4、3、2-3、2、1-2和1。
它用于對ISO105-A02所描述的色牢度測試中發生的變色進行評估。
其在運用光牢度標準對光牢度測試進行分級時也很重要。
沾色灰卡：
該灰卡由九對無光的白色小片組成，顯示可分辨的染色深度。提供對應的牢度等級，即5、4-5、4、3-4、3、2-3、2、1-2和1。
它用于評估牢度測試期間發生的貼襯未染色織物上的染色的總量。
其使用方法在ISO105-A03中有描述。
