GB/T 5211.1-2003 Determination of water-soluble matter in pigments - Cold extraction method

This standard specifies the general test method for determining the content of soluble matter in cold water of pigment samples. GB/T 5211.1-2003 Cold extraction method for determination of water-soluble matter in pigments GB/T5211.1-2003 Standard download decompression password: www.bzxz.net

GR/T 5211.1—-2003/ISO 787-8:20G0 This standard adopts the standard 150787:200 for the physical quality of materials with water-soluble substances. This standard replaces the cold extraction method specified in G.521.11 for pigments. The main technical differences between this standard and G.521.1-1DR are as follows: The original standard uses 1S07878:1570: This standard specifies the "centrifugal separation step"; this standard specifies the "conditions for the use of wetting agents"; this standard adds the following: "For some requirements of the joint guarantee" GB521 international standard

This standard is effective from the date of implementation of B311.185, and is proposed by the International Petrochemical Association: This standard is a comprehensive test method for the pigment standard. The origin of this standard is: China National Chemical Corporation Changzhou Coatings Chemical Research Institute. The principal is: Shen Ranjiangling. This standard was first revised and issued in 2008, and the first revision is 2018. 1. Specification GB/T 5211.12003/I50 78/-8.2000 Determination of water-soluble pigments by cold extraction method. This standard specifies the method for determining the content of water-soluble pigments in cold water. GB/Y5211.2 specifies the method for determining the content of water-soluble pigments by hot extraction method: For most materials and materials, these two test methods will produce different test results. Therefore, the company's technical requirements should clearly indicate the new method used, and indicate the new method used in the test report.
Note: This method is for the delivery of old materials and the delivery of clear materials. It is not necessary to indicate the cost of the material in the product specification and indicate the properties of the material; when the material is not fixed by the instrument, the material is measured in different ways.
