GB/T 12680.1-1990Alcohol soluble dyes -- Determination for general properties of application (English PDF)

Foreword

This standard replaces GB/T 12680.1-1990 "Determination of alcohol soluble dyes and the relative strength of the shade", GB/T 12680.2-1990 "Determination of insoluble matter content of soluble dyes in ethanol," Determination of GB/T 12680.3-1990 "soluble dyes in ethanol solubility Method ", GB/T 12680.4-1990" Determination of light fastness of alcohol soluble dyes "and GB/T 12680.5-1990" soluble dyes heat resistance Measurement method. " 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).

The standard proposed by China Petroleum and Chemical Industry Association.

This standard by the National Standardization Technical Committee Dye (SAC/TC134) centralized.

This standard was drafted. State Key Laboratory of Fine Chemicals, Dalian University of Technology, Shenyang Chemical Research Institute.

1 Scope

This standard specifies the relative intensity and shade of alcohol soluble dye in ethanol insoluble content and solubility, light resistance, heat resistance and ash test methods.

This standard applies to the relative strength and shade of alcohol soluble dye in ethanol insoluble content and solubility, light resistance, heat resistance and ash Determination.
