GB/T 19746-2018金属和合金的腐蚀 盐溶液周浸试验

本标准规定了一种在盐溶液中有、无外加应力下通过周浸试验来评估金属耐蚀性的方法。本标准适用于包括铝合金和钢铁材料在内的金属在制造过程中的质量控制，也适用于合金研发过程中的评定。根据试验溶液的化学成分，本标准可模拟海水飞溅区、除冰液和酸性盐环境的腐蚀效应。本标准中术语“金属”包括有或没有防腐层的金属材料。周浸试验适用于：——金属及其合金；——某种金属覆盖层(相对于基体是阴极性和阳极性覆盖层)；——某种转化膜；——某种阳极氧化层；——金属表面的有机涂层。

DIN EN 14562-2006化学消毒剂和防腐剂.评估医学领域用器械灭真菌或酵母菌作用的定量病媒试验.试验方法和要求(第2阶段，第2步)

This EN specifies a test method (phase 2/step 2) and requirements for the minimum fungicidal and yeasticidal activity of chemical disinfectants products that form a homogeneous, physically stable preparation in hard water and that are used for instrument disinfection in the medical area whether this instruments are defined as medical devices or not. This includes products used for the disinfection of surgical instruments, anaesthetic equipment, endoscopes etc. which are disinfected by immersion into the product.

BS EN 14348-2005化学消毒剂和防腐抗菌剂.评定包括仪器消毒剂在内的医用化学消毒剂灭分支杆菌活性用定量悬浮试验.试验方法和要求(阶段2,步骤1)

This document specifies a test method and the minimum requirements for mycobactericidal (or tuberculocidal) activity of chemical disinfectant products that form a homogeneous, physically stable preparation when diluted with hard water - or in the case of ready-to-use products - with water. Products can only be tested at a concentration of 80 % or less as some dilution is always produced by adding the test organisms and interfering substance.nThis document applies to products that are used in the medical area including those that are covered by the EEC/93/42 Directive on Medical Devices.nThis document applies to areas and situations where disinfection is medically indicated. Such indications occur in patient care, for example:nin hospitals, in community medical facilities and in dental institutions; nin clinics of schools, of kindergartens and of nursing homes;nand may occur in the workplace and in the home. It may also include services such as laundries and kitchens supplying products directly for the patients.nNOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.nNOTE 2 This method corresponds to a phase 2, step 1 test (see Annex E).
