21、st needs of different applications. The difference between this European Standard and previous national standards lies in the technique used for the determination of the integral efficiency. Instead of mass relationships, this technique is based on particle counting at the most penetrating particle
22、size (MPPS), which is for micro-glass filter media usually in the range of 0,12 m to 0,25 m. This method also allows the testing test ultra low penetration air filters, which was not possible with the previous test methods because of their inadequate sensitivity. For membrane and synthetic filter me
