BS EN 597-1:2015EN 597-1:2015 (E) 4 Introduction This European Standard is one of a series of standards concerned with the ignitability of mattresses and upholstered bed bases using different ignition source

20、s. The ignition source used in this European Standard is a smouldering cigarette. When mattresses or bed bases are used or stored on their own, it is desirable to know their ignitability in their own right. It cannot be assumed that protection against flaming sources will automatically give protecti

21、on against smouldering ignition. Users of the standard should therefore recognize the need to submit test specimens to both cigarette and flaming ignition tests. WARNING Attention is drawn to the fact that the tests given in the test report (see Clause 10) are not intended to reproduce the full fire

22、 hazards that may be encountered. BS EN 597-1:2015EN 597-1:2015 (E) 5 1 Scope This European Standard specifies a test method to assess the ignitability of mattresses, upholstered bed bases or mattress pads when subjected to a smouldering cigarette as an ignition source. Air mattresses and water beds

23、 are excluded from this standard. The standard contains one annex: Annex A (informative) Model test report form. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 progressive smouldering exothermic oxidation, not accompanied by flaming, that is

24、 self-propagating, i.e. independent of the ignition source, which may or may not be accompanied by incandescence 2.2 flaming undergoing combustion in the gaseous phase with the emission of light 2.3 flammability ability of a material or product to burn with a flame under the specified test condition

25、s 2.4 ignitability measure of the ease with which a material, product or component can be ignited so as to flame or progressively smoulder 2.5 ignition source source of energy used to ignite combustible materials or products 2.6 mattress pad upholstered product that is used in conjunction with, and

26、to complement, a mattress or upholstered bed base 2.7 mattress upholstered product intended for sleeping upon 2.8 bed base structure that supports a mattress or the surface(s) of a mattress that support(s) a user 2.9 upper surface surface of a bed base that supports a mattress or the surface(s) of a

27、 mattress that support(s) a user BS EN 597-1:2015EN 597-1:2015 (E) 6 3 Criteria of ignition 3.1 Progressive smouldering ignition For the purposes of this European Standard, all the following types of behaviour are considered to be progressive smouldering ignitions: a) any test assembly that displays

28、 escalating combustion behaviour so that it is unsafe to continue the test and active extinction is necessary; b) any test assembly that smoulders until it is largely consumed within the test duration; c) any test assembly that smoulders to its full thickness, within the duration of the test; d) any

29、 test assembly that smoulders after one hour from the application of the ignition source; e) any test assembly that, on final examination (see 9.3), shows evidence of progressive smouldering. NOTE In practice it has been found that there is usually a clear distinction between materials which can cha

30、r under the influence of the ignition source but which do not propagate further (non-progressive combustion) and those where smouldering develops in extent and spreads (progressive combustion). 3.2 Flaming ignition For the purposes of this European Standard, a flaming ignition is considered to be th

31、e occurrence of any flames initiated by a smouldering source. 4 Principle To subject a full upper surface or upper surface characteristic features of a mattress, the bed base or the mattress pad to the contact of a smouldering ignition source by using smouldering cigarettes so that all the zones hav

32、ing different characteristics are tested. 5 Health and safety of operators 5.1 General The test method specified in this European Standard presents a considerable hazard; suitable precautions shall be taken, which may include the provision of breathing apparatus and protective clothing. 5.2 Enclosur

33、e For safety, the test should be conducted in a non-combustible fume cupboard. If such a cupboard is not available, a test enclosure should be constructed (see 6.2) so that the operator is protected from the fumes. 5.3 Extinguishers Adequate means of extinguishing the assembly should be provided bea

34、ring in mind that some combinations may produce severe flaming during the test. A hand and/or fixed water spray which can be directed over the burning area can be useful. Other means such as suitable fire extinguishers, fire blankets and a bucket of water will assist. In some cases smouldering may b

35、e difficult to extinguish completely and complete immersion in water may be necessary. BS EN 597-1:2015EN 597-1:2015 (E) 7 6 Apparatus 6.1 Test rig Consisting of a platform of expanded steel or open mesh at least 450 mm x 450 mm supported at least 75 mm above a solid base (a suitable test rig mesh i

36、s illustrated in Figure 1). The size of the mesh is not critical. For the tests, the rigs shall be sited within the enclosure (see 6.2) and the testing shall be performed in a basically draught-free environment permitting an adequate supply of air and removal of smoke from the area of the apparatus.

37、 Dimensions in millimetres Key A mesh made from wire approximately 2 mm in diameter X test rig width at least test specimen width Y test rig length at least test specimen length Figure 1 Test rig assembly BS EN 597-1:2015EN 597-1:2015 (E) 8 6.2 Test enclosure The test enclosure shall consist of eith

38、er a room with a volume greater than 20 m3(which contains adequate oxygen for testing) or a smaller enclosure with a through flow of air. Inlet and extraction systems providing an air speed rate of less than 0,2 m/s in the locality of the rig provide adequate oxygen without disturbing the burning be

39、haviour. 6.3 Clock The clock shall be capable of measuring to at least 1 h with an accuracy of 1 s. 6.4 Ignition source smouldering cigarette An un-tipped cylindrical cigarette complying with the following requirements shall be used: length: (68 2) mm; diameter: (8 0,5) mm; mass: (0,85 0,15) g. The

40、smouldering rate shall be (7,5 2) min/40 mm, when tested as follows. Mark the cigarette, conditioned as described in 7.1 at 10 mm and 50 mm from the end to be lit. Light it as described in 9.2.1 and impale it horizontally in air (air speed rate less than 0,2 m/s) on a horizontal wire spike inserted

41、not more than 13 mm into the unlit end. Record the time taken to smoulder from the 10 mm to the 50 mm mark. The smouldering rate shall be measured on one cigarette from a batch of 20 cigarettes. The smouldering rate may be measured on two cigarettes at the same time. The distance between cigarettes

42、and between each cigarette and any nearby surface such as the wall or floor of the test enclosure shall be at least 150 mm. If the cigarette ceases smouldering before reaching the 50 mm mark, the measurement of smouldering rate shall be repeated. 7 Atmospheres for conditioning and testing 7.1 Condit

43、ioning The materials to be tested and the cigarettes shall be conditioned for at least 24 h immediately before the tests in the following atmosphere: temperature: (23 2) C; relative humidity: (50 5) %. 7.2 Atmosphere for testing The test shall be carried out in an atmosphere having a temperature bet

44、ween 10 C and 30 C and a relative humidity between 15 % and 80 %. 8 Test specimen 8.1 General The test assembly materials shall be representative of the components and make-up of the finished mattress, mattress pad or upholstered bed base. BS EN 597-1:2015EN 597-1:2015 (E) 9 8.2 Small scale For smal

45、l scale tests, the test specimen shall be rectangular in shape and have a minimum size of 450 mm x 450 mm x nominal thickness of the finished mattress, mattress pad or upholstered bed base. The type of proposed edge finishing system shall be incorporated, e.g. plain, piped or taped edge. Representat

46、ive tension shall be maintained in the cover. The proposed mattress, mattress pad or upholstered bed base finish shall be represented in the specimen, e.g. tufted or quilted. NOTE Representative tension can be maintained in the cover by means of suitable clips if the section is produced by cutting.

47、8.3 Full size For full size tests 1:1, the actual product shall form the test specimen. 9 Test procedure 9.1 Preparation NOTE The application of the ignition source can be within 20 min of removing the test materials from the conditioning atmosphere (7.1). If there is a significant distance between

48、the conditioning room and the room where testing is carried out, the materials can be protected against de-conditioning during transfer between rooms. If possible, the assembly can be prepared inside the conditioning room. 9.1.1 Ensure that means of extinguishing are close to hand (see 5.3). 9.1.2 F

49、or a small scale test, place the test specimen in the test rig (see 6.1). For full size tests: bed bases are tested on a horizontal surface (feet of the bed bases may have to be fitted if they exist on the actual product; mattresses or mattress pads are tested on a horizontal surface. 9.2 Ignition source application 9.2.1 Within 20 min of removing the materials from the conditioning atmosphere, light two cigarettes and draw air through it until the tip glows brightly. Not less than 5 mm and not more than 8 mm of the cigarette shall
