家具燃烧测试 : 第二部分：通过明火对衬垫家具组分的可燃性的测试方法
1. APPLICATION AND LIMITATION应用和局限
The purpo of this test guide is to provide guideline for asssing the ignitability of upholstered composites for covers and filling, when subjected to flaming sources of thermal output ranging from that just greater than from a burning match as might be applied accidentally in the u of upholstered ats. It does not cover ignition caud by deliberate acts of vandalism
本测试指南是为判断物料的可燃性提供了指导，例如衬垫家具用的面料和填充物需经受大于火柴热量燃烧的意外情况。但是不包括故意的人为原因造成的燃烧情况。
2. PRINCIPLE准则
The principle is to subject an asmbly of upholstery materials arranged to reprent, in styl
ized form, the join between back (or at and arm) such as is typical in chairs, to six flaming sources lected to cover the intensities of actual sources that might be encountered in various end u environments.
本准则适用于衬垫家具物料以固定形式，组成椅子的形状，然后经受在不同的应用环境中的6种明火火源的测试。
3.Definitions 定义
3.1 Progressive smouldering ：
Exothermic oxidation, not accompanied by flaming, that is lf- independent of the ignition source. It may or not be accompanied by incandescence.
进行性闷烧：放热的氧化反应，没有火焰伴随发生，即独立火源自行蔓延，也有可能没有白热现象。
3.2 Flaming. 厨师求职网明火燃烧
Undergoing combustion in the gaous pha with the emission of light.
发光的气相燃烧
4. EQUIPMENT AND CHEMICAL REAGENT设备和化学药品
4.1 Test rig 测试架
员工关系岗位职责
A suitable test rig is illustrated in figures1 and figures2. it shall consist of two rectangular frames hinged together and capable of being locked at right angles to each other.
一个合适的测试框架。它包括两个矩形框，用铰链联结在一起，并能以垂直角度固定。
The frames shall be made from nominal 25mm×3mm steel flat bar and shall curely hold mesh steel platforms t 6±1mm below the top edge of the frames。
框用25mm×3mm钢条制成，中间牢固的装一块钢网平台，该网比框顶边低6mm±1mm。
The internal width and height of the back frame shall be 450±2mm×300±2mm and the width and depth of the ba frame 450±2mm×150±2mm.A standard edging ction may be ud around the mesh steel platform to give protection and greater rigidity.
背筐内部宽和高为450±2mm×300±2mm，座框内部的宽和高450±2mm×150±2mm。钢网平台四周包边对钢网起保护和增强的作用。
The side of the frame shall extend beyond the back of each frame to provide for the hinge
qq注销空间holes and to form the back legs. The hinge holes and to form the back legs. The hinge rod shall be of nominal 10mm diameter steel, continuous across the back of the rig and its axis22.5±0.5mm beyond the back member of each frame.
框的侧边应延伸超过底（后）边以便钻铰链孔，侧边延伸同时形成后腿。铰链轴为文化局局长Φ10mm钢轴，轴线距格框底（后）边22.5±0.5mm。
The frames are lockable at right angles by a bolt or pin through each of the pairs of members forming the back legs. The front legs may be welded across the front corners of the ba frame. The height of the legs shall be such as to leave a gap not less than 50mm high between the ba and frame and the supporting surface.
利用穿过各框两组后腿的螺栓和插销，可以把两框固定成直角。两前腿焊接斜挎座框两前角。腿的高度以使坐框底距支撑面50mm为宜。
For the tests the rig shall be sited within the enclosure 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.
测试框架置于隔离区内，测试应在自由通风的环境下进行，以便有适当的空气供应，同时可以把仪器周围的烟排除。
4.2 Test enclosure 测试环境
The test enclosure shall consist of either a room with a volume greater than 20m3(which contains adequate oxygen for testing) or a smaller enclosure with a through flow of air. Inlet and extraction systems providing air flow rates of 0.02 to 0.2m/s in the locality of the rig provide adequate oxygen without disturbing the burning behaviors.
测试环境应是一个大于20m3的空间（这将包含测试所需的适量氧气），或者小一点的、空气流通的空间，进排气系统应使在框架位置的空气流速为0.02～0.2 m/s，这样即可提供适量氧气又不至于干扰燃烧行为。
4.3 Stop-watch 计时器
一信
The clock shall be capable of measuring to at least 1h with an accuracy of 1s.
计时器量程不小于1h，精度为1s。
4.4 Butane flame ignition source 2: gas flow rate is 160±5ml/min at 25oC or 157±5ml/min at 20廉洁的名人名言oC (approximately 145mm flame height)； Butane flame ignition source 3：gas flow rate is 350±10ml/min at 25oC or 344±10ml/min at 20oC (approximately 200 mm flame height)；
丁烷火源2：气体流量160±5毫升/分钟（25 oC）或者57±5毫升/分钟（20oC）（火焰大约145毫米高）丁烷火源3：气体流量350±10毫升/分钟（25 oC）或者344±10毫升/分钟（20oC）（火焰大约200英语语法基础入门毫米高）

5. CRITERIA OF FAILURE 失败标准
5.1 Progressive smouldering failure 进行性闷烧失败
5.1.1 for source 2: any composite that produces externally detectable amounts of smoke,
heat or glowing 30 min after the removal of the burner tube.
对于火源2：任何物料移开火源30分钟后，从外表上可以看到大量的烟、热、光。
5.1.2 for source 5: any composite that produces externally detectable amount of smoke, heat or glowing 60 min after ignition of the crib.
