DIN EN 1827:2009-11 EN 1827:1999+A1:2009 (E) 4 Introduction A given respiratory protective device can only be approved when the individual components satisfy the requirements of the test specif
23、ication 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 not tested then simulation of the apparatus is permitted pro
24、vided the respiratory characteristics and weight distribution are similar to those of the complete apparatus. 1 Scope This European Standard specifies performance requirements, test methods and marking requirements for half masks (re-usable) without inhalation valves and with separable filters (desi
25、gned for a maximum of single shift use) to protect against gases or gases and particles or particles only. It does not cover devices designed for use in circumstances where there is or might be an oxygen deficiency (oxygen less than 17 % by volume) or for escape purposes. Laboratory and practical pe
26、rformance tests are included for the assessment of compliance with the requirements. 2 Normative references !The following referenced documents are indispensable for the application of this document.

31、he definitions in EN 132 and the nomenclature from EN 134 apply. Gas filters remove specified gases. Combined filters remove dispersed solid and/or liquid particles and specified gases. The term “gases“ is taken to include vapours. Particle filters remove solid and/or liquid particles. A solid aeros
32、ol is defined as a dispersion of solid particles in air. A liquid aerosol is defined as a dispersion of liquid particles in air. 4 Description A half mask without inhalation valves covers the nose and mouth and the chin, has no inhalation valves and may or may not have exhalation valves. It comprise
33、s a facepiece and separable and replaceable filters. It provides adequate sealing for the intended use on the face of the wearer against the ambient atmosphere, when the skin is dry or moist and when the head is moved. Inhalation air enters through the filter and passes directly to the nose and mout
34、h area of the device. Exhaled air passes through the filter and an exhalation valve (if fitted) to the ambient atmosphere. In addition to providing protection against gases these devices can be designed to protect against both solid and liquid aerosols. 5 Classification 5.1 General Half masks shall
35、be classified according to the types and classes of filters used. 5.2 Filter types Type FM A - for use against certain organic gases and vapours with a boiling point higher than 65 C as specified by the manufacturer. Type FM B - for use against certain inorganic gases and vapours as specified by the
36、 manufacturer (excluding carbon monoxide). Type FM E - for use against sulfur dioxide and other acid gases and vapours as specified by the manufacturer. Type FM K - for use against ammonia and organic ammonia derivatives as specified by the manufacturer. DIN EN 1827:2009-11 EN 1827:1999+A1:2009 (E)
37、6 Type FM AX - for use against certain low boiling organic compounds as specified by the manufacturer. Type FM SX - for use against specific named gases and vapours. !Type FM P NR - for single shift use against particles.“ Any combination of these types is permitted. 5.3 Filter classes 5.3.1 Gas fil
38、ter classes Class 1 - low capacity (Gas 1). Class 2 - medium capacity (Gas 2). The protection provided by class 2 devices includes that provided by the corresponding class 1 device of the same type. FM AX and FM SX filters are not classified. 5.3.2 Particle filter classes !Class 1 low filtering effi
39、ciency (FM P1 NR). Class 2 medium filtering efficiency (FM P2 NR). Class 3 high filtering efficiency (FM P3 NR). The protection provided by a FM P2 NR - or FM P3 NR - filter also includes that provided by the corresponding filter of lower class or classes.“ 6 Designation Respiratory protective devic
