第一部分：用香烟点火源对软座进行易燃性评价的试验方法BS5852 PartI：1979

1.APPLICATION AND LIMITATION应用和局限

The purpose of this test guide is to provide guideline for assessing the ignitability of material combinations e.g.covers and filling used in upholstered seating when subjected to either a smouldering cigarette or a lighted match as might be applied accidentally in the use of upholstered seats.It does not cover ignition caused by deliberate acts of vandalism.

本测试指南是为判断物料的可燃性提供指导，例如对衬垫家具用的面料和填充物进行香烟焖烧或明火燃烧测试，就如在使用过程中可能会受到香烟的焖烧或明火的燃烧,但是不包括故意的和人为原因造成的燃烧情况。

2.PRINCIPLE原理

The principle is to subject an assembly of upholstery materials arranged to represent,in stylized form,the join between back(or seat and arm) surfaces of a chair to two sources of ignition;one being a smouldering cigarette,and the other a flaming

source approximating to the calorific output of a burning match.

测试原理是用固定的方法将衬垫家具物料安装成椅子，然后在椅子的背部和底座的交接处放两种火源，观察其阻燃性能，一种是香烟，另一种是明火，类似于火柴产生的热量。

4.1Conditioning and Testing平衡和测试

The materials to be tested and the cigarette should be conditioned immediately before the test for72hr in indoor ambient conditions and then for at least16hr at20±5°C and50±20% RH.

测试前，物料和香烟应在室内平衡72小时，然后在温度为20±5°C和湿度为50±20%条件下平衡至少16小时。

For testing,a substantially draught-free environment having a temperature of 15-30°C and a relative humidity of45

±25%shall be used.

测试环境温度为15-30°C，湿度为45±25%，空气能够充分流通

4.2Genera

l综述

The test piece materials shall be representative of the cover,filling and other components to be used in the upholstery composites.

测试材料必须是衬垫家具中有代表性的面料、填充物或者其他的组成成分。

4.3Cover material and fabric interliner 面料和里料

The cover size needed for each test is

800±10mm x650±10mm.The long dimension shall be cut parallel to the selvedge.The cover may be constructed from smaller pieces of test materials provided that the resulting seams do not occur within100mm of the area likely to be affected by the test.The cover shall have triangular

cut-outs352mm from one end on both sides.The cut-outs shall be positioned such that when assembled on the test rig the lie of any pile is down the back assembly and from the hinge to the front of the base frame.The side of

cut-outs shall be50mm base and

110mm high.

每个面料测试的样板大小为800±10毫米x650±10毫米。长度方向平行于布边。如果面料由小块组合而成，但是接缝部位必须在火源100毫米以

外，以使其不影响测试。在面料的两侧距离底部352毫米处分别剪一个三角形。此三角形底部50毫米，高110毫米。

Where a fabric interliner is used it is cut to the same dimensions,and in the same orientation as the cover,for fitting to the test rig under the cover.如果有里料，则剪成同样的尺寸，方向

与面料相同，放在面料下面一同安装在装置上。

4.4Upholstery filling

填充料

Two pieces of filling,one450±

5mm×300±5mm×75±2mm thick and the other450±5mm x150±5mm x75±2mm thick,are required for each test.

每次测试需要两块填充料，一块为450±5mm×300±5mm×75±2mm厚，另一块为450±5mm x150±5mm x75±2mm（厚）,

Some cushioning assemblies may consist of several layers that may be typically felt,wadding or various foams.Where the total thickness exceeds75mm,the upper 75mm of the cushioning assembly

is reproduced.

一些坐垫由几层构成，包括毡片、软填料或几种不同的海绵。如总厚度超过了75毫米，超过75毫米的部分将重新制作。

Where the filling is less than75 mm thick the test piece is built up to the required thickness by adding to the underside a further layer of the bottom material.

如厚度小于75毫米，则加厚底部材料使样板厚度达到要求。

5.PROCEDURE

5.1步骤

5.1P reparation准备

5.1.1Open out the test rig and thread the covering fabric and,if used,the fabric interliner,behind the hinge bar so that the cut outs are aligned with the hinge bar打开测试架，将面料和里料

（如果用）固定在装置上，使剪成的

部分平行于铰链。

5.1.2Place the filling pieces under the covering fabric(s)and locate the filling pieces in the frame recesses.将填充物放在面料下面，然后安装在测试装置上。

5.1.3Lock the frames at right angles by the bolts or pins ensuring that the filling components are not displaced. Fasten the fabric(s)over the top, bottom and sides of the frame using clips and ensure that the fabric(s)is secured and under even tension.This is done by allowing approximately20 mm of fabric to wrap around the frame so that the edge of the fabric just contacts the expanded metal.将装置放置成直角并用螺丝固定住，防止填充

物滑移。用夹子将面料的上部、底部

和侧部夹紧，使面料保持一定张力。

使面料经向大约20毫米左右夹在装

置上。

5.2香烟闷烧Smouldering cigarette

5.2.1Light a cigarette(Clause 3.4)and draw air through it until the tip glows brightly.Not more than8mm of the cigarette shall be consumed in this operation.

点燃香烟，通过其吸空气直到燃烧旺盛。在此操作过程中香烟的损失不能超过8毫米

5.2.2Place the smouldering cigarette in position along the junction between the vertical and horizontal test pieces,allowing at least50mm from the nearest

side edge,or from any marks left by any previous test,to the cigarette and simultaneously start the clock.

将闷烧的香烟放在垂直面和水平面的交界处，到边缘的距离以及到原来留下的测试标记至少为50毫米，同时按动秒表，记录时间。

5.2.3Observe the progress of combustion,and record any evidence of progressive smouldering or flaming in the interior and/or cover.

观察燃烧的进展情况，并记录内部或

表面闷烧和产生明火的现象。

5.2.4If progressive smouldering or if flaming of the upholstery components is observed at any time within a period of one hour of the placement of the cigarette, extinguish the test piece and record a failed result for the smouldering cigarette test.

如果在放置香烟一个小时内观察到强烈的闷烧或明火，扑灭测试样板，并记录未通过香烟闷烧测试。

5.2.5

If progressive smouldering or if flaming is not observed within the one hour period or if the cigarette fails to smoulder its complete length,repeat the test with a new cigarette length, repeat the test with a new cigarette placed in a fresh position not less than50mm from any previous test damage.If progressive snouldering or if flaming is not observed in this retest or if the cigarette fails to smoulder its complete length, record a pass result for the

smouldering cigarette test unless the test piece fails the final examination in5.4.Otherwise extinguish the test piece and record a failed result.如果强烈的闷烧或明火在放置香烟一个小时内没有观察到或香烟未能燃完，则用新的香烟在新的位置上重复测试，与上一个测试标记的距离不小于50毫米。如果再重复测试中没有发现强烈的闷烧或明火或香烟未能燃完，并通过了5.4规定的最终检查，则记录样板通过香烟闷烧测试，否则记录未通过测试。

5.3Butane flame test丁烷明火测试

5.3.1Light the butane emerging from the burner tube,adjust the gas flow to the appropriate rate and allow the flame to stabilize for at least2minutes.点燃丁烷气体，调整气体至合适的流量，并稳定2分钟。

5.3.2Position the burner tube axially along the junction between the seat and back so that the flame is not less than 50mm from the nearest side edge or any marks left by any other previous test,and simultaneously start the clock.将火源放在坐垫和靠背交界处，并与交界线平行，并且到边缘的距离以及

到原来留下的测试标记不小于50毫米，同时按动秒表开始计时。

5.3.3Allow the gas to burn for a period of20±1s,then terminate by carefully removing the burner tube from the test pieces.

保持火焰燃烧20±1秒，然后终止并从样板上小心的移开火源。

5.3.4

Observe for flaming or progressive smouldering in the interior and/or cover.Disregard flames,afterglow, smoking or smouldering that cease within120s of the removal of the burner tube.观察内部或表面闷烧和产生明火的现象。忽略移开火源后的

120秒内的明火、暗烧、烟、光等现象。

5.3.5If flaming or progressive smouldering of the upholstery components is observed extinguish the test piece.Record a failed result for the butane flame ignition source1test.如果观察到明火或强烈的闷烧，扑灭测

试样板，并记录未通过丁烷明火火源1的测试。

5.3.6If flaming or progressive smouldering is not observed,repeat the test at a fresh position as described in 5.3.2.If flaming or progressive smouldering is not observed in this retest record a pass result for the butane
