评估可清洁过滤器介质特性退化的试验方法

[中文适用范围]： 本国际标准规定了评估清洁式过滤介质工业应用下相对降解特性的标准参考试验方法。主要目的是通过模拟测试条件获得关于长期暴露于模拟气体条件下过滤介质性质变化的信息。该标准主要针对非织造布过滤器，因为它们常在与本国际标准描述的测试气体相似的情况下使用。这些测试结果不用于预测完整规模过滤装置的绝对性能，但有助于袋式过滤器的设计、选择和开发合适的清洁式过滤介质，以及识别合适的操作参数。 [外文原描述]： ISO 16891:2016 specifies a standard reference test method useful to assess the relative degradation characteristics of cleanable filter media for industrial applications under standardized simulated test conditions. The main purpose of testing is to obtain the information about relative change of properties of filter media due to exposure to the simulated gas conditions for a long time. The main target of this International Standard is the property change of nonwoven fabric filters because they are frequently used under similar circumstances to the test gas conditions described in this International Standard. The results obtained from this test method are not intended for predicting the absolute properties of full scale filter facilities. However, they are helpful for the design of a bag filter and selection and development of appropriate cleanable filter media, and for the identification of suitable operating parameters.
