This European Standard shall be given the status of a national standard, either by
18、 publication of an identical text or by endorsement, at the latest by November 2009, and conflicting national standards shall be withdrawn at the latest by November 2009. This European Standard supersedes !EN 149:2001“. This European Standard was approved by CEN on 8 March 2001 and includes Corrigen

The modifications of the related CEN Corrigendum have been implemented at the appropriate places in the text and
20、are indicated by the tags . This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an i
21、ntegral part of this standard. Annex A is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, Fran

Introduction A given respiratory protective device can only be approved when the individ
23、ual components satisfy the requirements of the test specification which may be a complete 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 no
24、t tested then simulation of the apparatus is permitted provided the respiratory characteristics 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
25、against particles except for escape purposes. Laboratory and practical performance tests are included for the assessment of compliance with the requirements.

29、ed to be used for more than a single shift“ 4 Description A particle filtering half 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)
30、 form an inseparable part of the device. It is intended to provide adequate sealing 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 fa
31、cepiece or, via an inhalation valve(s) if fitted. The exhaled air flows through the 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
32、are classified according to their filtering efficiency and their maximum total inward 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 filteri
33、ng half masks are classified as single shift use only or as re-usable (more than one shift).“ DIN EN 149:2009-08 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 h

35、l test samples shall meet the requirements. 7.2 Nominal values and tolerances Unless 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 %
36、 Unless otherwise specified, the ambient temperature for testing shall be (16 - 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 Partic
37、le filtering half masks shall be offered for sale packaged in such a way that they 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 whic
38、h the particle filtering half mask is designed to be used. After undergoing the 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 accord
39、ance with 8.3.1 and 8.3.2 the particle filtering half mask shall not collapse. Any 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
40、particle filtering half mask is designed to be re-usable, the materials used shall withstand the cleaning and disinfecting agents and procedures to be specified by the manufacturer.“ DIN EN 149:2009-08 EN 149:2001+A1:2009 (E) 7 Testing shall be done in accordance with 8.4 and 8.5. !With reference to
41、 7.9.2, after cleaning and disinfecting the re-usable particle filtering half 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 und
42、er realistic conditions. These general tests serve the purpose of checking the 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
43、 shall provide full details of those parts of the practical performance tests 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 don

The total inward leakage consists of three components: fa
45、ce seal leakage, exhalation valve leakage (if exhalation valve fitted) and filter 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 sh
