Introduction A given respiratory protective device can only be approved when the individual components satisfy the requirements of the test specification which may be a complet
24、e standard or part of a standard, and practical performance tests have been carried out successfully on complete apparatus where specified in the appropriate standard. If for any reason a complete apparatus is not tested then simulation of the apparatus is permitted provided the respiratory characte
25、ristics and weight distribution are similar to those of the complete apparatus. 1 Scope This European Standard specifies minimum requirements for filtering half masks as respiratory protective devices to protect against particles except for escape purposes. Laboratory and practical performance tests
26、 are included for the assessment of compliance with the requirements.

29、poses of this European Standard the definitions given in EN 132 and the nomenclature given in EN 134 apply !together with the following: 3.1 re-useable particle filtering half mask particle filtering half mask intended to be used for more than a single shift“ 4 Description A particle filtering half
30、mask covers the nose and mouth and the chin and may have inhalation and/or exhalation valve(s). The half mask consists entirely or substantially of filter material or comprises a facepiece in which the main filter(s) form an inseparable part of the device. It is intended to provide adequate sealing
31、on the face of the wearer against the ambient atmosphere, when the skin is dry or moist and when the head is moved. Air enters the particle filtering half mask and passes directly to the nose and mouth area of the facepiece or, via an inhalation valve(s) if fitted. The exhaled air flows through the
32、filter material and/or an exhalation valve (if fitted) directly to the ambient atmosphere. These devices are designed to protect against both solid and liquid aerosols. 5 Classification Particle filtering half masks are classified according to their filtering efficiency and their maximum total inwar
33、d leakage. There are three classes of devices: FFP1, FFP2 and FFP3. The protection provided by an FFP2 - or FFP3 - device includes that provided by the device of lower class or classes. !In addition, particle filtering half masks are classified as single shift use only or as re-usable (more than one
34、 shift).“ BS EN 149:2001+A1:2009 EN 149:2001+A1:2009 (E) 6 6 Designation Particle filtering half masks meeting the requirements of this European Standard shall be designated in the following manner: !Particle filtering half mask EN 149, year of publication, classification, option (where “D“ is an op
35、tion for a non re-useable particle filtering half mask and mandatory for re-useable particle filtering half mask).“ !EXAMPLE Particle filtering half mask EN 149:2001 FFP1 NR D “ 7 Requirements 7.1 General In all tests all test samples shall meet the requirements. 7.2 Nominal values and tolerances Un
36、less otherwise specified, the values stated in this European Standard are expressed as nominal values. Except for temperature limits, values which are not stated as maxima or minima shall be subject to a tolerance of 5 %. Unless otherwise specified, the ambient temperature for testing shall be (16 -
37、 32) C, and the temperature limits shall be subject to an accuracy of 1 C. 7.3 Visual inspection The visual inspection shall also include the marking and the information supplied by the manufacturer. 7.4 Packaging Particle filtering half masks shall be offered for sale packaged in such a way that th
38、ey are protected against mechanical damage and contamination before use. Testing shall be done in accordance with 8.2. 7.5 Material Materials used shall be suitable to withstand handling and wear over the period for which the particle filtering half mask is designed to be used. After undergoing the
39、conditioning described in 8.3.1 none of the particle filtering half masks shall have suffered mechanical failure of the facepiece or straps. Three particle filtering half masks shall be tested. When conditioned in accordance with 8.3.1 and 8.3.2 the particle filtering half mask shall not collapse. A
40、ny material from the filter media released by the air flow through the filter shall not constitute a hazard or nuisance for the wearer. Testing shall be done in accordance with 8.2. 7.6 Cleaning and disinfecting !If the particle filtering half mask is designed to be re-usable, the materials used sha
41、ll withstand the cleaning and disinfecting agents and procedures to be specified by the manufacturer.“ BS EN 149:2001+A1:2009 EN 149:2001+A1:2009 (E) 7 Testing shall be done in accordance with 8.4 and 8.5. !With reference to 7.9.2, after cleaning and disinfecting the re-usable particle filtering hal
42、f mask shall satisfy the penetration requirement of the relevant class. Testing shall be done in accordance with 8.11.“ 7.7 Practical performance The particle filtering half mask shall undergo practical performance tests under realistic conditions. These general tests serve the purpose of checking t
43、he equipment for imperfections that cannot be determined by the tests described elsewhere in this standard. Where practical performance tests show the apparatus has imperfections related to wearers acceptance, the test house shall provide full details of those parts of the practical performance test
44、s which revealed these imperfections. Testing shall be done in accordance with 8.4. 7.8 Finish of parts Parts of the device likely to come into contact with the wearer shall have no sharp edges or burrs. Testing shall be done in accordance with 8.2. 7.9 Leakage 7.9.1 Total inward leakage The laborat
45、ory tests shall indicate that the particle filtering half mask can be used by the wearer to protect with high probability against the potential hazard to be expected. The total inward leakage consists of three components: face seal leakage, exhalation valve leakage (if exhalation valve fitted) and f
46、ilter penetration. For particle filtering half masks fitted in accordance with the manufacturers information, at least 46 out of the 50 individual exercise results (i.e. 10 subjects x 5 exercises) for total inward leakage shall be not greater than 25 % for FFP1 11 % for FFP2 5 % for FFP3 and, in add
47、ition, at least 8 out of the 10 individual wearer arithmetic means for the total inward leakage shall be not greater than 22 % for FFP1 8 % for FFP2 2 % for FFP3. Testing shall be done in accordance with 8.5. BS EN 149:2001+A1:2009 EN 149:2001+A1:2009 (E) 8 7.9.2 Penetration of filter material The p
48、enetration of the filter of the particle filtering half mask shall meet the requirements of Table 1.
