WHG/T2883—1997
This standard is a revision of GB/T3675-83, with some additions and partial changes in technical content. The important technical differences between this standard and GB/T3675 are as follows: 1. Add three requirements for water resistance, acid resistance and oil resistance; 2. Delete the easily dispersible varieties; 3. Change the names of the two items of color and water to color and volatile matter at 105℃ respectively; 4. Change the relative tinting strength index from the original 95% to 105% to not less than 100%, and change the sieve hole diameter from 800μm to 400um. Both indicators are improved compared with the previous version. 5. Convert the test methods of color, tinting strength, water, water-soluble matter, oil absorption and heat resistance in GB/T3675 into corresponding new national standards. 6. This standard replaces GB/T3675-83 from the date of implementation. This standard is proposed by the Technical Supervision Department of the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee for Standardization of Paints and Pigments. Drafting unit of this standard: Changzhou Paint Chemical Research Institute of the Ministry of Chemical Industry. The main drafters of this standard are Zheng Wenjuan and Jin Liandi. I
