What Is The FFP3 Mask
FFP3 mask refers to masks that meet European (CE EN1409: 2001) standards. The standards of European protective mask are divided into three levels: FFP1, FFP2, FFP3. It is different from the American standard in that it uses a detection flow rate of 95 L / min and uses DOP oil to dust.
The FFP3 category of masks, both European and American standards, are specified for testing with the American TSI-8130 Automated Filter Testers. The American standard uses the NaCl method for class N, the DOP method for class R, and the DOP method for European standards.
The TSI-8130 instrument uses the NaCl method. The instrument can automatically generate salt particles. The average diameter of the particles is 0.2 μm (aggregated average diameter 0.26 μm, the arithmetic average diameter of 0.07 μm). The sample is set to pass through the sample at a certain flow rate, and the instrument automatically prints the flow rate, resistance, and transmittance.
According to the tested particle transmission rate, it is divided into three levels: P1 (FFP1), P2 (FFP2), P3 (FFP3). FFP1 Minimum filtering effect ≥80%，FFP2 Minimum filtering effect ≥94%，FFP3 Minimum filtering effect ≥97%.
