GB/T 22592-2008 stipulates the general rules for the determination of pH value of water treatment agents. It is suitable for all kinds of water treatment agents, covering sample collection and preparation to ensure that the samples are representative. The pH value is determined by instruments such as acidity meters, and the instrument calibrating, measurement operation steps and environment requirements are detailed, such as temperature, electrode use specifications, etc. It also clarifies the measurement result recording and processing methods to ensure the accuracy and reliability of the measurement results. This standard provides an important basis for the quality control of water treatment agents, helps to ensure the effect of water treatment, and is widely used in the production, testing and water purification of water treatment agents.
