(14/1521119 The color of the pigment can be determined by the national standard 7: Replaced by B#211.21985, the standard is issued by the China Petroleum Chemical Industry Association and the technical committee of the China Petroleum Chemical Industry Association. Drafted by: China Chemical Industry Corporation, the main person in charge: Shen Sujiang, Qi Lu. This standard was issued for the first time in 1973 and revised in 1985. GH/T 521:.2-20C3/r5O 787-3:200 Determination of water-soluble pigments by hot extraction method
Sixth standard specifies the determination of the content of yellow pigments in samples in the general test method of the Foshan Institute of Technology: 51511.1 has formulated a method for determining the amount of yellow pigments in cold water. For most materials and pigments, this test method will give unspecified test results. Fourth, the technical requirements should clearly state the method used.
Jiangsu, Yunfangtoutongmai is used for what materials and quality materials in Jiang, the company's six product standards for pigments or any internal materials must follow this method and should be used in the materials of the company. What detailed changes are required? Only when the reverse method is not used for a certain material, the specifications will be different for the edge test.
2 National Normative Reference Documents
The following documents shall be engraved with the clauses that extend beyond the reference month of this standard. The next standard shall be selected for recording. All the notes shall be of the period The referenced documents, all subsequent amendments (excluding the blanks) or revisions are not applicable to this standard. However, the parties who have reached an agreement on this standard are the members of the new version of this document. From the date of the document, the new version is not applicable to this standard. R92851988 paint-free 1 disinfection surface seal material sample (cq150542: 1384) 3 reagents

5 Sampling
According to the 5th specification, take a representative sample of the test pigment. 6 Steps
e.1 General
Feasible determination of two
6.2 Sample
Weighing scale~2)) Accurate to the sample m around the weighing
GB/T 5211,2-2003/150 787-3.20GC The amount of sample to be used shall be determined based on the type of inflammatory substance and the salt content of the aqueous solution. In any case, the sample collected in repeated tests or in tests between several different experiments shall be consistent. 6.3 Adjust the volume to 200 ml (3 ml or less for the sample with a lubricant of 5% slurry, unless otherwise specified). If the sample shows a generally smooth and semi-solid property, it may be treated with a coagulant, provided that the selected flocculation system does not affect the subsequent determination of the water acid and the fee is not exceeded. Use a small amount, quickly cool the suspension device to room temperature and move it through the plate (4.1) to the Chinese currency ladder to the engraving craftsman to take the reward of shaking the meter to reach the point of no discussion, use the magic stock through the method device (1 through the game: the ground liquid is returned to the method device to filter the fine. Let: If your material is not in the request, you can use the certificate to profit. In or out of the case of 2 moments, several people have the body of the agent, in the immediate science! The said that the wet agent U ring can be trusted, and the test piece is in the test piece. Then the annual user test must be carried out: the drum result> the piece is properly calibrated. The filter can be avoided by the filter. Transfer 10 0L completely clear filtered or separated liquid is pre-dried and weighed in a drying apparatus (10 ± 2) for ten minutes. After cooling in a drying apparatus (10 ± 2), weigh the residual material in a drying apparatus (7.7) for ten minutes (maximum 500 mg). The final value of the residual material is not much different from the final value, and the non-thermal interval is at least Hmin. Record the residual material mass (m). The lower value of the last two weighings is used to calculate the water migration potential. Rate: E
m: - sample mass, unit is gram (g): m, - "- reduced mass or. Unit is gram!!, 122.5
If the values ​​of the two determination results are not greater than 105% of the lower value, calculate and report the arithmetic mean. If it is greater than 12%. The arithmetic mean of the three determination results shall be taken for the first determination. The difference between the third determination and the half mean of the other determination values ​​shall also be less than 10. The test setting description shall be compared and the single test light prohibition shall be stated.
Report two decimal places on the special card.
