The full performance testing of purified water includes two parts: chemistry and microbiology. The chemical testing is carried out in the physical and chemical laboratory, including pH, conductivity, easy oxide testing, non-volatile matter testing, etc.; The microbiological test is mainly the detection of the limit of microorganisms, which is carried out in the local 100-level ultra-clean bench under the level of 10,000 in the microbial limit room. By testing the above purified water indicators, the water quality is controlled to meet the requirements of "Chinese Pharmacopoeia 2020", "Medical Device Manufacturing and Management Regulations", and "Sterile Medical Device Manufacturing and Management Regulations" (YY0033), so as to control the cleaning effect of the product and the accuracy of the experimental results.
