A device that may be used for supporting this type of mate-rial is an additional U-shaped frame, wider than the U-shaped frame con-taining the specimen, spanned by 10-mil wires of heat-resistant composition at 25 mm intervals, inserted over the bottom U-shaped frame.S5.1.4A bunsen burner with a tube of 10 mm inside diameter is used. The gas adjusting valve is set to provide aNat’l Highway Traffic Safety Admin., DOT§571.303flame, with the tube vertical, of 38 mm in height. The air inlet to the burner is closed.S5.1.5The gas supplied to the burn-er has a flame temperature equivalent to that of natural gas.S5.2Preparation of specimens.S5.2.1Each specimen of material to be tested shall be a rectangle 102 mm wide by 356 mm long, wherever pos-sible. The thickness of the specimen is that of the single or composite mate-rial used in the vehicle, except that if the material’s thickness exceeds 13 mm, the specimen is cut down to that thickness measured from the surface of the specimen closest to the occupant compartment air space. Where it is not possible to obtain a flat specimen be-cause of surface curvature, the speci-men is cut to not more than 13 mm in thickness at any point. The maximum available length or width of a specimen is used where either dimension is less than 356 mm or 102 mm, respectively, unless surrogate testing is required under S4.1.1.S5.2.2The specimen is produced by cutting the material in the direction that provides the most adverse test re-sults. The specimen is oriented so that the surface closest to the occupant compartment air space faces downward on the test frame.S5.2.3Material with a napped or tufted surface is placed on a flat sur-face and combed twice against the nap with a comb having seven to eight smooth, rounded teeth per 25 mm.S5.3Procedure.(a) Mount the specimen so that both sides and one end are held by the U-shaped frame, and one end is even with the open end of the frame. Where the maximum available width of a speci-men is not more than 51 mm, so that the sides of the specimen cannot be held in the U-shaped frame, place the specimen in position on wire supports as described in S5.1.3, with one end held by the closed end of the U-shaped frame.(b) Place the mounted specimen in a horizontal position, in the center of the cabinet.(c) With the flame adjusted according to S5.1.4, position the bunsen burner and specimen so that the center of the burner tip is 19 mm below the center of the bottom edge of the open end of the specimen.(d) Expose the specimen to the flame for 15 seconds.(e) Begin timing (without reference to the period of application of the burner flame) when the flame from the burning specimen reaches a point 38 mm from the open end of the specimen.(f) Measure the time that it takes the flame to progress to a point 38 mm from the clamped end of the specimen. If the flame does not reach the speci-fied end point, time its progress to the point where flaming stops.(g) Calculate the burn rate from the formula:B = 60 × (D/T)Where:B = Burn rate in millimeters perminuteD = Length the flame travels in milli-meters, andT = Time in seconds for the flame to travel D millimeters.[36 FR 22902, Dec. 2, 1971, as amended at 40 FR 14319, Mar. 31, 1975; 40 FR 42747, Sept. 16, 1975; 40 FR 56667, Dec. 4, 1975; 63 FR 28954, 28956, May 27, 1998; 63 FR 51003, Sept. 24, 1998]§571.303Standard No. 303; Fuel sys-tem integrity of compressed naturalgas vehicles.S1.

汽车内饰材料燃烧测试简述及发展趋势
汽车内饰材料燃烧测试简述及发展趋势作者：匡龙来源：《科技资讯》 2013年第21期匡龙(深圳市计量质量检测研究院广东深圳 518000)摘要:本文首先对国内外汽车内饰材料燃烧测试标准进行简述,其次分析国内外之间的差异,最后结合当今现状,预测我国汽车内饰材料的发展趋势。
关键词:内饰材料燃烧测试中图分类号:O657.3 文献标识码:A 文章编号:1672-3791(2013)07(c)-0077-02作为内饰材料质量判定的重要标准之一,内饰材料燃烧试验的重要性不言而喻。
本文主要介绍了我国和一些西方国家对汽车内饰材料燃烧特性的评价体系,并结合我国的具体情况,分析了我国汽车内饰材料评价体系的不足之处,并提出今后的发展方向。
1 国内外汽车内饰材料燃烧测试标准的简述1.1 我国汽车内饰材料燃烧测试标准简述1987年,我国出台了最早的汽车内饰材料燃烧测试标准GB8410-1987,并于1994年进行了第一次修订。
2006年1月份,我国又重新修订该标准,于7月份开始正式施行。
该标准参考了美国联邦车辆安全标准FMVS S571.302《汽车内饰材料的燃烧性能》,进一步指导我国的汽车内饰材料的生产。
GB8410-2006是我国唯一的汽车内饰材料燃烧测试强制性标准,构建起了一个有效的内饰材料测试体系,为汽车行业的良性发展做出了较大贡献。
标准要求内饰材料的燃烧速度不大于100 mm/min。
1.2 国外汽车内饰材料燃烧测试标准简述国外对汽车内饰材料燃烧测试均有较高的要求。
1995年10月,欧盟通过95/28/EC号指令,规定了公共汽车和客车在制造时内部所用的材料燃烧必须满足最低要求。
见表1美国将汽车产品设计制造纳入社会管理的法律体系,授权汽车安全、环保、节能等部门指定汽车技术法规。
1966年9月,美国颁布实施《国家交通及机动车安全法》,授权美国运输部(DOT)对乘用车、多用途乘用车、载货车、挂车、大客车、学校客车、摩托车以及这些车辆的装备和部件制定并实施联邦机动车安全标准(简称FMVSS)。
fmvss302阻燃标准和v0对比
文章标题：深度解析FMVSS302阻燃标准与V0对比在当今社会中，汽车安全一直是人们关注的焦点。
而作为汽车安全的重要指标之一，阻燃性能更是备受关注。
在这篇文章中，我们将深度解析FMVSS302阻燃标准与V0对比，旨在帮助读者全面了解这两种标准并做出更加科学的选择。
一、FMVSS302阻燃标准1. 了解FMVSS302标准FMVSS302标准是美国联邦汽车安全标准的一部分，旨在规定车辆内部材料的阻燃性能要求。
具体来说，经过FMVSS302测试的材料在燃烧测试中不能产生持续的明火，并且其平均燃烧速度不能超过100mm/min。
这一标准的制定，有效地提高了汽车内部材料在火灾发生时的阻燃性能，从而减少了火灾造成的人身伤害和财产损失。
2. FMVSS302标准的优势FMVSS302标准的制定，无疑提高了汽车内部材料的阻燃性能，从而增加了车辆的安全性。
车辆内部采用符合FMVSS302标准的阻燃材料，一旦发生火灾，能够有效地延缓火势蔓延，给车内的乘客争取更多的逃生时间，降低伤亡事故的发生概率。
FMVSS302标准对于汽车安全具有重要意义。
二、V0阻燃等级1. 了解V0阻燃等级V0阻燃等级是指材料在垂直状态下进行燃烧测试时，在火焰移除后，试样不应该出现燃烧，且燃烧物体的时间应该小于10秒。
这一等级是电子电气设备领域常用的阻燃等级，用于评定材料在火灾发生时的燃烧性能。
2. V0阻燃等级的应用V0阻燃等级广泛应用于电子电气设备领域，例如电路板、插座、电源适配器等。
采用V0阻燃等级的材料能够有效降低电子电气设备在火灾发生时的燃烧风险，保障了设备的安全可靠运行。
三、FMVSS302与V0对比分析1. 不同领域的应用FMVSS302标准主要应用于汽车行业，旨在提高汽车内部材料的阻燃性能；而V0阻燃等级主要应用于电子电气设备领域，用于评定电子电气设备材料的阻燃性能。
两者的应用领域不同，因此在具体选择时需要根据实际情况进行考虑。

5.1.4使用带有一根内径为10mm的管子的本生灯。
设置煤气调节阀以提供火焰，管子垂直放置，高度为38mm。
本生灯进气口关闭。
5.1.5 输送到燃油器的气体具有与天然气等同的燃烧温度。
5.2 样品准备
5.2.1 在条件允许的情况下，每种材料都应提供长度356mm，宽度102mm的长方形试样。
试样的厚度应该是用于机动车的单一或复合材料的厚度，以下情况除外：如果材料的厚度超过13mm，则把材料的厚度减少
到这样的标准，即从材料最接近乘员舱空气间层的表面测量的厚度。
如果由于材料表面的曲线而没有办法获得一个平坦的材料，则把材料表面的任何点的厚度减少到只有13mm。
若某种材料可提供的最大尺寸样品亦无法达到上述长度356mm或宽度102mm的标准，则这种材料的试样应以可提供的最大尺寸样品为准，但依照第4.1.1节的规定应进行替代品测试的材料除外。
5.2.2 试样应通过按照可能对测试结果产生最不利影响的方向切割材料而获取。
试样的方向应使最接近乘员舱空气间层的表面向下面向检测框架。
5.2.3 如果所用材料表面是毛绒状或簇状物，应置于平稳表面上，并用一个有七八个光滑圆齿、间距为25mm 的梳子逆着毛绒梳理两次。
5.3 试验过程
（a）安装这个材料时，使其两边和一头能够被U型构架支撑而另一头甚至跟U型构架的敞口部分相连接。
在最大的可用材料宽度最多有51mm的地方，材料两边不能被U型构架支撑，这时候就要像第5.1.3节中所规定的那样，把材料放在一头由U型构架的非敞口端支撑的可以由绳线来支撑的位置。
（b）把安装好的材料水平放在柜子中心。
（c）按照第5.1.4节的规定对喷灯火焰进行调整。
然后调整本生灯和试样的位置，确保该喷灯位于该样品未被卡住一端的下方，且该喷灯顶端的中心与该试样端下缘的间距为19mm。
（d）使试样暴露于框架几秒钟。
（e）当来自燃烧体的火苗与试样一个敞口的距离达到38mm时，开始计时（不包括对于火苗的应用的时间）。
（f）计算使火苗从试样的固定尾部燃烧到38mm时所用的时间。
如果火苗没有燃烧到规定的点，就计算到火苗熄灭那个点的时间。
（g）按照以下公式计算材料的燃烧速率：
B=60×（D/T）
其中：B代表燃烧速率，单位为mm/min；
D代表火焰行程，单位为mm；
T代表火焰行程达到Dmm时所花费的时间，单位为秒。
