Aperçu de conformité

Champ d’application

This standard applies to fully automatic electric washing machines intended for household and similar use that explicitly claim to have antibacterial and sterilizing functions. It is mandatory for all manufacturers declaring such features. Please note that ordinary single-tub and double-tub washing machines are excluded from this scope. It is used in conjunction with GB 21551.1-2008.

Exigences techniques

The standard specifies the essential hygiene safety requirements and sterilization performance for applicable washing machines. It defines specific terms such as ozone eliminating bacterial, silver ion eliminating bacterial, and high temperature eliminating bacterial (where high temperature is defined as washing temperatures ≥80°C). Regarding performance, the standard mandates that the eliminating bacterial rate must meet a minimum threshold after a standard wash cycle. Furthermore, the standard sets durability requirements, requiring the washing machine to maintain a specific sterilization rate after continuous operation for a designated number of cycles or hours, depending on whether it is an impeller/agitator or drum type. Manufacturers must also comply with strict labeling requirements. The user manual must clearly state the type of sterilization function, the achieved bacterial elimination rate, performance degradation over the lifespan, and any parts requiring replacement or cleaning.

Méthodes d’essai

The evaluation involves a comparative test between a control group (standard wash without sterilization) and a test group (standard wash with sterilization). The test uses specific cotton cloth loads and sample blocks contaminated with Staphylococcus aureus and Escherichia coli. The eliminating bacterial rate is calculated by comparing the residual viable bacteria counts before and after the wash cycle.

Questions fréquentes

What products are regulated under GB 21551.5-2010?

It regulates fully automatic electric washing machines for household use that claim antibacterial or sterilizing functions. Ordinary single or double-tub machines are not covered.

What are the specific bacteria used for testing in this standard?

The standard specifies the use of Staphylococcus aureus and Escherichia coli to evaluate the eliminating bacterial rate.

Are there durability requirements for the sterilization function?

Yes, the washing machine must maintain a minimum sterilization rate after continuous operation for 2000 cycles (impeller/agitator type) or 2300 hours (drum type).
