家用洗衣机 微生物性能测量方法

[中文适用范围]： 本技术规范提供了一种在标准化条件下，使用被测试微生物污染的纺织品测量家用洗衣机微生物污染减少性能的测试方法。测量洗涤程序前后污染纺织品上的微生物数量，并计算减少量。此外，还测量了洗涤程序中从污染纺织品到未污染纺织品的潜在交叉污染。 本文件不涉及由于洗涤剂、漂白系统或任何添加剂的潜在或声称的抗菌作用而导致的微生物污染减少。 本文件适用于家用洗衣机，包括洗衣干衣机的洗涤相关功能。 本文件不适用于专业洗衣机，也不适用于与食品服务、医院床单或其他非住宅应用相关的商业洗衣操作。 本文件涉及家用和类似用途电器使用导致的微生物污染减少的测量程序。本文件规定了可重复测量的方法。这些测量结果只能用于相对陈述。绝对陈述，即与健康相关的声明或关于疾病预防或治疗或健康改善的结论，保留给医学评估后的明确监管行动。 本文件不适用于医疗、兽医或制药应用中使用的设备。 本文件不涉及消毒、灭菌措施。 [外文原描述]： 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.
