28、his European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 1998, and conflicting national standards shall be withdrawn at the latest by July 1998. This European Standard has been prepared under a mandate

29、 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 a, which is an integral part of this standard. According to the CENICENELEC Internal Regulations, the

31、m. Page 4 EN 136:1998 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 standard, and successfull practical performance tests have been carried out on

32、 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 distribution are similar to those of the complete apparatus. 1 Scope This European S

33、tandard specifies minimum requirements for full face masks for respiratory protective devices. Full face masks for diving apparatus are not included in the scope of this European Standard. Laboratory and practical performance tests are included for the assessment of compliance with the requirements.

38、 exposed to a source of radiant heat Page 5 EN 136: 1998 3 Definition For the purposes of this standard the definitions given in EN 132 and the nomenclature given in EN 134 apply together with the following. A full face mask is a facepiece which covers the eyes, nose, mouth and chin and provides ade

39、quate sealing on the face of the wearer of a respiratory protective device against the ambient atmosphere, when the skin is dry or moist, and even when the head is moved or when the wearer is speaking. 4 Description Air enters the full face mask through the connector(s) and passes either directly to

40、 the nose and mouth area or via the eye (visor) area of the full face mask. The exhaled air flows back either through the connector into the breathing apparatus (closed-circuit breathing apparatus, pendulum breathing) or directly to the ambient atmosphere, via the exhalation valve(s), or by other ap

41、propriate means in other types of respiratory protective devices. An inner mask may be used to separate the nose and mouth from the eye (visor) area(s) of the full face mask. 5 Classification Three classes of full face masks are described, each providing the same level of respiratory protection but

42、having some differences which reflect intended areas of application. Class 1: Full face masks for light duty use. Class 2: Full face masks for general use. Class 3: Full face masks for special use. 6 Designation Designation of a full face mask meeting the requirements of this standard: Full face mas

43、k EN 136 (Class) (Options). 7.1 General In all tests, all test samples shall meet the requirements. 7.2 Nominal values and tolerances Unless otherwise specified, the values stated in this standard are expressed as nominal values. Except for temperature limits, values which are not stated as maxima o

44、r minima shall be subject to a tolerance of k 5 Oh. Unless otherwise specified, the ambient temperature for testing shall be (24 k 8) “C, the temperature limits shall be subject to an accuracy of 2 1 “C and the relative humidity shall be (50 2 30) %. Page 6 EN 136:1998 7.3 Visual inspection The visu

45、al inspection shall include that of the marking and of any information to be supplied by the manufacturer. Testing shall be done in accordance with 8.3. 7.4 Materials For class 2 and class 3 full face masks exposed parts i.e. those which may be subjected to impact during use of the apparatus shall n

46、ot be made f aluminium, magnesium, titanium or alloys containing such proportions of these metals as will, on impact, give rise to frictional sparks capable of igniting flammable gas mixtures. Testing shall be done in accordance with 8.3. 7.6 Resistance to temperature Before and after this test the

47、full face mask shall meet the requirement of 7.16. Following the conditioning in accordance with 8.2 and after being allowed to return to ambient temperature the full face mask shall show no appreciable deformation and any incorporated threaded connector to EN 148-1, EN 148-2 or EN 148-3 shall be ga

48、uged and shall comply with the appropriate standard. In addition with class 3 full face masks, the threads specified in EN 148-i, EN 148-2 or EN 148-3 as appropriate shall also be accurate according to the gauge, at the end of the conditioning period in accordance with 8.2 b. Testing shall be done i

49、n accordance with 8.3, 8.4, 8.13 and 8.16. 9.6.1 General Before and after these tests the full face mask shall meet the requirement of 7.16. 7.6.2 Class 1 full face masks Parts of the full face mask that might be exposed to a flame during use shall not burn or continue to burn for more than 5 s after removal from the flame. Testing shall be done in accordance with 8.3 and 8.5.1. 7.6.3 Class 2 and class 3 full face masks Parts of the full face mask that might be exposed to a flame during use shall not burn or continue to burn for more than 5 s after removal from the
