This standard and GB/T 12680.1-1990, GB/T 12680.2-1990, GB/T 12680.3-1990, GB/T 12680.4-
1990 and GB/T 12680.5-1990 compared to the main changes are as follows.
--- 5 standard will integrate into a standard "soluble dyes general performance measurement" (the title of this edition);
--- Increased the determination of ash content of soluble dyes (Chapter 8 of this edition);
--- Increasing the content of the test report (Chapter 9 of this edition).

3 Determination of alcohol soluble dyes and the relative strength of the shade
3.1 Principle
The soluble dyes and standards specimens measuring its optical density of the solution at the same time using a spectrophotometer. According to standard strength of the sample is calculated
Relative intensity. Shade were visually assessed.
3.2 Reagents and materials
Reagents and materials shall comply with the relevant provisions of GB/T 2374-2007 in Chapter 3.
95% (volume fraction) ethanol. chemically pure, shall comply with the provisions of GB/T 679's.
3.3 instruments and equipment
Instruments and equipment shall comply with the relevant provisions of GB/T 2374-2007 in Chapter 4.
3.3.1 Analytical Balance. a sense of the amount of 0.0001g;
3.3.2 spectrophotometer;
3.3.3 colorimetric tube. 50mL.
3.4 Test Method
3.4.1 Determination of the relative intensity of the test solution preparation
Weigh the sample and standard dye several grams (specified in the product standard), weighing accuracy of 0.0002g. They were placed in 100mL beaker
