Detailed Product Description

HZ-9514 Bacterial Filtration Efficiency Tester (BFE)

Equipment Overview

It used to test the percentage of respirator material removed from the bacteria - containing suspended particles at a specified flow rate. The dual-air path sampling method improves the accuracy of sampling, which is applicable to the performance test of bacterial filtration efficiency of medical surgical masks by metrological verification departments, scientific research institutes, medical mask manufacturers and other relevant departments

 

 

Standardization

  • Q/0212 ZRB003-2011 Surgical mask Bacterial filtration efficiency (BFE) detector
  • YY0469-2004 Surgical mask Bacterial filtration efficiency (BFE) detector technical request
  • YY/T 0969-2013 Standard for bacterial detection of disposable medical masks
