GB/T 5750.7-2006 Standard examination methods for drinking water—Aggregate organic parameters
Abstract
This standard replaces the oxygen consumption in Appendix A of GB/T 5750-1985. The main changes compared with GB/T 5750-1985 are as follows: — The structure is adjusted according to GB/T 1.1-2000 "Guidelines for Standardization Work - Part 1: Structure and Writing Rules for Standards" and GB/T 20001.4-2001 "Rules for Standard Writing - Part 4: Chemical Analysis Methods"; — The quantity and units of measurement are modified according to the requirements of national standards; — The equivalent concentration is changed to molar concentration (the equivalent concentration is still retained in the oxidation-reduction part); — The symbol for mass concentration is changed from C to ρ, and the symbol for content is changed from M to m; — Seven test methods for three indicators, including biochemical oxygen demand (BOD5) in drinking water, petroleum, and total organic carbon, are added.
