酸性电解水生成器卫生要求

GB 28234-2020 is a current mandatory Chinese national standard for Hygienic requirements for acidic electrolyzed water generator. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Aug 1, 2021.

Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.

Compliance overview

Scope and applicability

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.

Technical requirements

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.

Testing methods

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.

FAQs

What products are regulated under GB 28234-2020?

It regulates acidic electrolyzed water generators, specifically continuous types producing acidic electrolyzed-oxidizing water and slightly acidic electrolyzed water.

What are the key updates in GB 28234-2020 compared to the 2011 version?

The 2020 version adds requirements for slightly acidic electrolyzed water generators, updates definitions, and removes certain electrical safety and lifespan requirements from the previous edition.

Does GB 28234-2020 specify testing for viral inactivation?

Yes, it includes a mandatory appendix for Poliovirus inactivation testing to ensure the generated water effectively neutralizes viruses.
