The European standard for a complete powered air filtering device incorporating a face helmet, visor or head cover is EN12941. There is no separate classification for particle filters (P) in the standard EN12941 as the particle filter is part of the system classification. Standard EN12941 defines three classes of performance (TH1, TH2 and TH3). The numbers define the level of performance (inward leakage) and the pull strength of the breathing tubes and couplings within the classification. Inward leakage for classification TH1 is maximum 10%, for TH2 maximum 2% and for TH3 maximum 0.2%. Assigned Protection Factor Guide: (TH1P) - APF of 10 x Workplace Exposure Limit, (TH2P) - APF of 20 x Workplace Exposure Limit, (TH3P) - APF of 40 x Workplace Exposure Limit.
