Introduction

Key specifications of Model ZR-1000 mask bacteria filtration efficiency tester (BFE) not only meet the requirements of B.1.1 in YY0469-2011 <technical requirements for medical surgical masks>, but also meet the requirements of ASTMF2100, ASTMF2101 and European EN14683 standards. What’s more, we made innovative improvements based on this, with double gas contrast sampling method at the same time, improve the precision of sampling. It is applicable to the performance test of the mask bacterial filtration efficiency by the metrological verification department, scientific research institutes, mask manufacturers and other relevant departments.
