GB/T 6682-2008 stipulates the specifications and test methods of analytical laboratory water. The standard specifies the index requirements of different levels of analytical laboratory water in terms of acid alkalinity, conductivity, oxidation substance content, etc., and elaborates the test process of corresponding indicators, such as conductivity Measuring method, acid alkalinity detection method, etc. According to this standard, it can ensure that the mass of laboratory water meets the needs of analytical experiments, provide basic guarantee for the accuracy of experimental data, and is widely used in various analytical laboratories. It is the key basis for mass control of laboratory water.
