不同定标方法的多次通过试验结果分析

Analysis of Multi-pass Test Results with Different Calibration Methods

应用GJB 3820-1999和ISO 16889-2008两种标准对3种型号的滤材分别进行过滤性能检测,得出相应的试验结果,并对试验结果进行对比分析。试验采用的粉尘都是ISO MTD,不过定标方法不同,GJB 3820-1999标准中采用ACFTD粉尘进行标定,ISO 16889-2008标准中用ISO MTD粉尘进行标定。测得的试验结果整体上较为接近,能够很好地反映出滤材的过滤性能。这对于AC FTD粉尘停产之后,仍然采用GJB 3820-1999标准进行检测试验具有重要的意义。

Filtration performance tests of three types of filter medium with GJB 3820-1999 and ISO 16889-2008 standards were introduced and their test results were analyzed. ISO MTD dust was used in both tests while ACFTD dust was used in calibration of standard GJB 3820-1999 and 1SO MTD dust was used in calibration of standard ISO 16889-2008. Test results are close overall with which filtration performance of filter materials can be reflect easily. It is important to use standard GJB 3820-1999 in the test since AC FTD dust is discontinued.
