标准范围

ISO 20743:2007规定了测定抗菌纺织品成品（包括非织造布）抗菌活性的定量试验方法。ISO 20743:2007适用于所有纺织品，包括用于服装、家居用品和杂项物品的布、絮、线和材料，无论使用的抗菌剂类型（有机、无机、天然或人造）或使用方法（内置、后处理或嫁接）。根据预期用途和纺织产品的使用环境，用户可以选择以下三种测定抗菌活性的方法中最合适的一种:a）吸收法（将测试细菌悬浮液直接接种到样品上的评估方法）；b） 转移法（将试验菌置于琼脂平板上并转移到样品上的一种评估方法）；c） 打印方法（将测试细菌放置在过滤器上并打印到样品上的一种评估方法）。菌落平板计数法和ATP（腺苷三磷酸）发光法也用于测量细菌计数。

ISO 20743:2007 specifies quantitative test methods to determine the antibacterial activity of antibacterial finished textile products including nonwovens.ISO 20743:2007 is applicable to all textile products, including cloth, wadding, thread and material for clothing, home furnishings and miscellaneous goods regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting).Based on the intended application and on the environment in which the textile product is to be used, the user can select the most suitable of the following three methods on determination of antibacterial activity: a) absorption method (an evaluation method in which test bacterial suspension is inoculated directly onto samples); b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto samples); c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto samples).The colony plate count method and the ATP (Adenosine Tri-phosphate) luminescence method are also specified for measuring the enumeration of bacteria.
