ISO 10121-1:2014旨在提供客观的实验室试验方法、建议的仪器、规范性试验部分和规范性试验,以评估用于一般过滤应用的气相空气净化设备的三种不同固体气相空气净化介质(GPACM)或GPACM配置。ISO 10121-1:2014专门用于挑战性试验,而不是一般材料评估或孔隙系统表征。ISO 10121-1:2014中确定的三种不同类型的GPACM是GPACM-LF(用于松散填充应用的不同形状和大小的颗粒)、GPACM-FL(用于扁平单层、褶皱或袋式装置的平板织物)和GPACM-TS(比平板厚很多倍的三维结构,例如用作装置中的成品元件)。
测试在气流中进行,GPACM配置在稳态条件下受到测试气体的挑战。由于使用了较高的气体挑战浓度(相对于一般通风应用),测试数据应用于在相同配置内比较GPACM,而不是用于预测实际情况下的性能。这也并不意味着可以直接比较不同的GPACM配置。主要目的是能够将同类GPACM配置与同类进行比较,而不是在GPACM配置之间进行比较。ISO 10121-2中描述了完整设备的测试。
为确保测试设备供应商的客观性,未定义测试设备的具体设计:附录中给出了一个示例。相反,规定了介质样品架设计、仪器性能和验证试验的规范性要求。
ISO 10121-1:2014 aims to provide an objective laboratory test method, a suggested apparatus, normative test sections and normative tests for evaluation of three different solid gas-phase air cleaning media (GPACM) or GPACM configurations for use in gas-phase air cleaning devices intended for general filtration applications. ISO 10121-1:2014 is specifically intended for challenge testing and not for general material evaluation or pore system characterization. The three different types of GPACM identified in ISO 10121-1:2014 are GPACM-LF (particles of different shape and size intended for e.g. Loose Fill applications), GPACM-FL (FLat sheet fabric intended for e.g. flat one layer, pleated or bag type devices) and GPACM-TS (three dimensional structures that are many times thicker than flat sheet and e.g. used as finished elements in a device). The tests are conducted in an air stream and the GPACM configurations are challenged with test gases under steady-state conditions. Since elevated gas challenge concentrations (relative to general ventilation applications) are used, test data should be used to compare GPACM within the same configuration and not for the purpose of predicting performance in a real situation. It is also not implied that different GPACM configurations can be directly compared. The primary intention is to be able to compare like GPACM configurations to like, not between GPACM configurations. Testing of complete devices is described in ISO 10121?2.
To ensure objectivity for test equipment suppliers, no specific design of the test apparatus is defined: an example is illustrated in an annex. Instead normative demands for media sample holder design, apparatus properties and validation tests are specified.
