ISO 16891:2016规定了一种标准参考试验方法，可用于在标准化模拟试验条件下评估工业用可清洁过滤介质的相对降解特性。测试的主要目的是获取由于长期暴露在模拟气体条件下而导致的过滤介质性能相对变化的信息。本国际标准的主要目标是非织造布过滤器的性能变化，因为它们经常在与本国际标准中描述的试验气体条件类似的情况下使用。 本试验方法所得结果不用于预测全尺寸过滤设施的绝对性能。 然而，它们有助于袋式除尘器的设计、选择和开发合适的可清洁过滤介质，以及确定合适的运行参数。

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.
