This paragraph is not equivalent to the use of national materials The standard A5TME200-1997 "Chemical Analysis and Calibration of Liquid Reagents - Preparation, Calibration and Preparation of Liquid Test Solution" is formulated based on the needs of chemical product analysis. Compared with ASTM F20 (1507), the standard has ten differences:
The "Required" in the short-circuit solution has been changed:
The indicator solution and indicator solution have been added with one additional item, nine items. The preparations and products to be classified into categories; preparations, products, reagent screening, differential screening, indicator solution, indicator device, and the product conditions are recorded in the Appendix A of this standard.
This standard was originally proposed by the State Administration of Chemical Industry and the Chemical Industry Policy and Regulations Department. This standard is under the technical jurisdiction of the National Chemical Standardization Technical Committee, especially the Inorganic Chemical Subcommittee. The maintenance unit of this standard is Tianjin Chemical Research and Design Institute. The main body of this standard is:
The second issue of this standard is:
This standard committee is responsible for the interpretation of the Inorganic Chemical Subcommittee of the Beijing Institute of Standardization Technical Committee. 41
