BS EN 1827:1999+A1:2009EN 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 specification which may be a complete standard or part of a s

24、tandard, 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 characteristics and weight distri

25、bution 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 (designed for a maximum of single shift use) to protect agai

26、nst 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 performance tests are included for the assessment of comp

27、liance with the requirements. 2 Normative references !The following referenced documents are indispensable for the application of this document.

32、N 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 aerosol is defined as a dispersion of solid particles in

33、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 comprises a facepiece and separable and replaceable filters.

34、 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 mouth area of the device. Exhaled air passes through the

35、 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 be classified according to the types and classes of

36、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 manufacturer (excluding carbon monoxide). Type FM E

37、 - 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. BS EN 1827:1999+A1:2009EN 1827:1999+A1:2009 (E) 6 Type FM AX - for use against certain low boilin

38、g 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 filter classes Class 1 - low capacity (Gas 1). Class

39、 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 efficiency (FM P1 NR). Class 2 medium filtering effic

40、iency (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 devices meeting the requirements of this European Stan
