This standard specifies the test methods and test devices for testing the efficiency and resistance of high efficiency and ultra-low-penetration-air filter medium and filter.
The test methods stated in this standard are applicable to the high efficiency and ultra-low-penetration-air filter medium and filter used for testing and filtration of particles in air. The testing for efficiency and resistance of sub-high-efficiency-particulate-air filter medium and filter may be carried out by reference to this method.
