GB/T 5750-2023 "Standard Test Methods for Drinking Water" implemented on October 1, 2023

The State Administration for Market Regulation (State Standardization Administration) has approved the release of GB/T 5750-2023 "Standard Testing Methods for Drinking Water", and the new standard will be implemented on October 1, 2023.

 

GB/T 5750 "Standard Testing Methods for Drinking Water", as a recommended national standard for testing techniques for drinking water, is an important technical support for GB 5749, in conjunction with GB 5749 "Hygienic Standards for Drinking Water". It provides a testing method basis for implementing GB 5749 and conducting health and safety evaluations of drinking water.

 

In 1985, it was first published as GB/T 5750-1985, and in 2006, it was first revised as GB/T 5750.1~GB/T 5750.13-2006. This is the second revision.

 

GB/T 5750 consists of 13 parts

01. General Provisions. The purpose is to provide the basic principles and requirements for water quality inspection.

02. Collection and preservation of water samples. The purpose is to provide the basic principles, measures, and requirements for water sample collection, preservation, management, transportation, and quality control of sampling.

03. Quality control of water quality analysis. The purpose is to provide quality control requirements and methods for water quality inspection and testing laboratories.

04. Sensory traits and physical indicators. The purpose is to provide corresponding testing methods for sensory traits and physical indicators.

05. Inorganic non-metallic indicators. The purpose is to provide corresponding testing methods for inorganic non-metallic indicators.

06. Metal and metalloid indicators. The purpose is to provide corresponding inspection methods for metal and metalloid indicators.

07. Comprehensive indicators of organic matter. The purpose is to provide corresponding testing methods for comprehensive indicators of organic matter.

08. Organic matter indicators. The purpose is to provide corresponding testing methods for organic matter indicators.

09. Pesticide indicators. The purpose is to provide corresponding testing methods for pesticide indicators.

10. Disinfection by-product indicators. The purpose is to provide corresponding testing methods for disinfection by-product indicators.

11. Disinfectant indicators. The purpose is to provide corresponding testing methods for disinfectant indicators.

12. Microbial indicators. The purpose is to provide corresponding testing methods for microbial indicators.

13. Radioactivity indicators. The purpose is to provide corresponding testing methods for radioactive indicators.
