DIN EN ISO 15957:2015-08 EN ISO 15957:2015 (E) 3 IntroductionFilters are subjected to evaluation of their initial performance and dust-loaded performance in

22、laboratory tests using specified test dusts. The results are to reflect the performance of the filter as installed in a building. However, since the properties of atmospheric aerosols vary to a large extent regionally, seasonally, and according to weather conditions, test data obtained with a given

23、test dust seldom accurately predict the filter performance as actually used. In addition to this, the test results with a given test dust might not be in agreement with those obtained by other laboratories because the filter performance is affected by many factors such as particle size distribution,

24、 particle agglomeration, and electrical charge. Despite these problems in testing filter performance, the test data are used for the classification of filters, estimation of energy consumption, Life Cycle Cost (LCC), and Life Cycle Assessment (LCA).The test dust used for evaluating initial performan

25、ce and loaded performance of filters can have a different specification from the dust used to achieve filter loading.This International Standard does not control the specification, manufacturing, or use of test dusts. It describes the properties of test dusts which can be used to load filters, and t

26、he requirements for test dust generation that will ensure that useful laboratory test results are obtained in order to mimic the actual use as much as possible.DIN EN ISO 15957:2015-08 EN ISO 15957:2015 (E) 4 1 ScopeThis International Standard defines the properties of load test dusts used for heati

46、 test dust contains coarse particles, but with very few larger than 100m. The adhesive force is small so that the particles are easily re-suspended. This particle mixture generally gives a small pressure drop increase when loaded on a filter, leading to a large consumption of test particles.9.3 L3 t
