Escopo e aplicabilidade

This standard specifies the hygienic requirements for sodium hypochlorite generators that produce sodium hypochlorite disinfectant. All technical contents within this standard are mandatory for manufacturers and relevant facilities. It applies to devices used for disinfecting general environmental surfaces, tableware, fruits, vegetables, fabrics, drinking water, swimming pool water, and sewage, but excludes specific testing rules not related to product hygiene.

Requisitos técnicos

The standard outlines strict requirements for main components, specifying that electrodes must be made of metals like titanium, platinum, ruthenium, or iridium, while graphite and lead dioxide electrodes are prohibited. The display system must reliably show parameters such as voltage, current, power, and flow rate. Regarding equipment and raw materials, the generator must include systems for automatic salt dissolution, electrolysis, and hydrogen exhaust. The salt used must be non-iodized, complying with GB 2721 or GB/T 5462, and the water must meet drinking water standards. For the generated sodium hypochlorite disinfectant, the standard sets limits on physicochemical indicators, including available chlorine content, pH, and flow rate. Heavy metal limits must be strictly adhered to when used for drinking water disinfection, and the disinfectant must meet specific microbial kill efficacy against bacteria, fungi, and viruses.

Métodos de ensaio

Testing procedures are defined to verify compliance, including the determination of available chlorine content and pH value according to the Technical Standard for Disinfection (2002). Flow rate testing follows GB/T 20621, while heavy metal analysis (lead, copper, cadmium) is conducted per GB/T 5750.6. Microbial kill efficacy is also evaluated using standardized suspension methods.
