Scope

Scope: This document specifies the filtration efficiency, filtration resistance, dust holding capacity, and the test method for the most easily penetrable particle size and the filtration efficiency corresponding to the most easily penetrable particle size of nonwoven filter materials against solid and liquid particles. This document is applicable to testing the filtration performance of textile filter materials against particles with a size range of 0.04-0.8μm. Method A is applicable to all types of textile filter materials. Method B is applicable to high-efficiency filter materials with a filtration efficiency greater than 99% as tested by Method A; Main technical content: Test conditions, sampling, test methods, result presentation, and reports for the filtration performance of air filter materials.
