IEC TS 63429:2023提供了一种测试方法，用于在标准化条件下测量带有被测试微生物污染的纺织品的家用洗衣机的微生物污染减少性能。在洗涤程序之前和之后测量被污染的纺织品上的微生物数量，并计算减少量。此外，测量洗涤程序内从受污染的纺织品到未受污染的纺织品的潜在交叉污染。 本文件不涉及由于洗涤剂以及漂白系统或任何添加剂的任何潜在或声称的抗微生物作用而导致的微生物污染减少。 本文件适用于家用洗衣机，其含义为TC 59的家用范围，包括洗衣机的洗涤相关功能-烘干机。 本文件不适用于专业洗衣机，也不适用于与食品服务、医院布草或其他非住宅应用相关的商业洗衣操作。 本文件涉及减少因使用家用和类似用途电器而导致的微生物污染的测量程序。本文件规定了实现可重复测量的方法。这些导出的测量结果只能用于相对陈述。绝对声明，即关于疾病预防或治疗或健康改善的健康相关声明或结论，保留用于医疗评估后的明确监管行动。 本文件不适用于预期用于医疗、兽医或制药应用的器械。 本文件不涉及消毒、消毒或灭菌措施。

IEC TS 63429:2023 provides a test method for measuring the microbial contamination reduction performance of household washing machines with textile pieces contaminated with test microorganisms under standardized conditions. The microbial numbers on the contaminated textile pieces are measured before and after the washing programme and the reduction is calculated. Furthermore, a potential cross contamination from contaminated to uncontaminated textile pieces within the washing programme is measured.
This document does not address the microbial contamination reduction due to any potential or claimed antimicrobial action of detergents as well as of bleach systems or any additives.
This document applies to washing machines for household use, within the meaning that the scope of TC 59 indicates for household use, including the washing related functions of washer-dryers.
This document does not apply to professional washing machines nor to commercial laundry operations associated with food service, hospital linens or other non-residential applications.
This document deals with measurement procedures regarding the reduction of microbial contamination resulting from the use of electrical appliances for household and similar use. This document specifies methods that enable reproducible measurements. These derived measurement results can only be used for a relative statement. Absolute statements, i.e., health-related claims or conclusions about prevention or treatment of a disease or health improvement, are reserved for explicit regulatory action after a medical assessment.
This document does not apply to appliances intended to be used in medical, veterinary, or pharmaceutical applications.
This document does not address sanitization, disinfection, or sterilization measures.
