Обзор требований
Этот обзор пока доступен только на английском языке.
Область применения
This standard applies to continuous acidic electrolyzed-oxidizing water generators and slightly acidic electrolyzed water generators, as well as the water they produce. It is applicable to manufacturers of disinfection equipment used in medical, food processing, and general environmental sanitation. It does not apply to non-continuous or batch-type generators. The standard references GB 5749 for drinking water compliance.
Технические требования
The standard specifies the hygienic and technical requirements for the main components of the generators, including the electrolytic cell, solution supply equipment, and storage containers. Components must be corrosion-resistant and free from extractables. It details the physicochemical parameters for both acidic electrolyzed-oxidizing water and slightly acidic electrolyzed water, covering pH values, oxidation-reduction potential (ORP), and available chlorine content. Furthermore, the standard outlines the microbial kill efficacy requirements for the generated water against specific pathogens like Staphylococcus aureus and Poliovirus. Manufacturers must ensure their products meet these mandatory disinfection performance benchmarks. It also includes safety requirements regarding heavy metal content and toxicological evaluation, referencing WS 628. The document provides detailed application scopes and usage methods for various scenarios, such as medical instrument disinfection, hand hygiene, and food surface treatment. Proper usage protocols must be strictly followed to ensure effective disinfection. It also covers packaging, transportation, and labeling requirements in accordance with the Disinfection Product Label and Instruction Management Specification.
Методы испытаний
Testing methods include evaluating the extractables of main components according to the 2001 Hygienic Safety Evaluation Specification. Physicochemical indicators and residual chloride ions are tested per GB/T 5750.5. The standard features a quantitative suspension test for bacteria (Appendix A) and a Poliovirus inactivation test (Appendix B) to verify microbial efficacy. Additionally, the service life of the electrolytic cell is tested using accelerated life testing methods referenced in HG/T 2471.
