FMVSS 214 ——侧面碰撞保护
联邦机动车安全标准FMVSS 214 侧面碰撞保护S1范围和目的(a)范围。
该标准详细说明了执行侧面冲击碰撞成员保护的要求。
(b)目的。
该标准的目的是减少乘员在侧面冲击碰撞中受到严重和致命伤害的风险。
包括乘用轿车,多功能乘用车,卡车和公共汽车。
碰撞测试中测试假人的加速度来评价汽车防撞性,测试侧门的强度要求。
S2适用(a)乘用轿车;(b)有效的1993.9.1标准中章节S3(a),S3(e),S3.1至S3.2.3,和S4应用于多功能乘用车,卡车和公共汽车,其车辆额定总重为10000磅或更少,除了可进人的运货车;(c)有效的1998.9.1标准中章节S3(f)和S5应用于多功能乘用车,卡车和公共汽车,其车辆额定总重为6000磅或更少,除了可进人的运货车,房车,拖车,自动倾卸卡车,救护车和汽车紧急救援车(包括军事火炮运载车),装配了座椅升高装置的车辆,和没有车门的车辆或专门设计为车门易拆卸的车辆。

将第572部分F类型测试假人放置在汽车被触击的侧面的前和后外侧座椅位置上。
然而,后座要求不能应用到前后轮之间轴距超过130英寸的乘用轿车上,或者乘用车的后座区域太小以致于不能按照S7配置要求容纳第572部分F类型的测试假人。
汽车侧面碰撞法规
汽车侧面碰撞法规2.1 概述制定汽车侧面碰撞法规的目的是为了降低在侧碰事故中乘员受重伤和致命伤害的风险,根据法规试验过程中测得的假人加速度,规定汽车的抗撞性能要求、车门加强要求和其他要求,以提高汽车侧面碰撞安全性。
汽车碰撞安全法规为消费者提供了一个系统、客观的汽车安全信息,能够促进企业按照更高的安全标准开发和生产,有效减少道路交通事故的伤害及损失。
美国是最旱执行汽车侧面碰撞保护法规的国家,1990年10月美国联邦机动车安全法规FMVSS 214(FMVSS,Federal Motor Vehicle Safety Standards)在美国颁布执行。
之后,在1995年10月,欧洲也制定了相应的汽车侧面碰撞法规ECE R95(ECE,Economic Commission for Europe)。
日本在侧碰撞方面的研究始于20世纪90年代初,相关法规于1998年正式纳入日本保安基准,其内容基本等同于欧洲ECER95。
我国强制性标准体系也采用欧洲ECE标准体系,为了便于与国际接轨,在我国制定侧面碰撞标准时是以ECE R95/02法规为蓝本,并结合我们国内的具体国情制定的。
由于我国人体与欧洲人体差异很大,所以在制定该标准时又参考了日本的相关法规。
标准于2006年7月1日开始实施,标准规定了汽车进行侧面碰撞的要求和试验程序,还对车辆型式的变更、三维H点装置、移动变形壁障及碰撞假人进行了规定。
美国、欧洲现有的侧面碰撞试验方法存在较多的不同之处,例如:碰撞形态不同,移动壁障的台车质量、尺寸,吸能块尺寸、形状、性能不同,试验用侧碰假人不同,碰撞速度不同,碰撞基准点的位置不同以及乘员伤害指标也略有不同。
在本章下面的内容中,将就这些方面进行详细的比较分析。
2.2 我国侧碰标准主要内容及评价指标标准内容主要涵盖碰撞试验方法、碰撞试验假人、假人的伤害指标、移动壁障的质量、吸能块的外形尺寸及刚度。
具体介绍如下。
2.2.1 碰撞形式移动变形壁障与静止试验车辆侧面垂直,并垂直撞向试验车辆。

– 安全气囊系统应区别对待:
• 传感器系统按照美国的FMVSS208、214开发,传感器系统标定 •
是气囊开发中工作量最大的,按照美国法规标定的气囊传感器系 统必然能够满足欧洲市场的要求 气囊模块针对美国和欧洲的法规要求及车型定位区别对待,美国 市场的气囊必须采用智能安全气囊,而同一车型的欧洲款可以根 据车型的情况适当地减少配置
气囊开发相关法规
主要涉及的中国法规有: 1、CMVDR294(关于正面碰撞乘员保护的设计规则) / GB11551(乘用车正面碰撞的乘员保护) 2、GB20071-2006(汽车侧面碰撞的乘员保护) 3.C-NCAP的要求并非强制性的,但是其测试、评定结果会公布在网上,对于整车安全性能 有很高要求。
• 乘员约束系统
• 正面安全气囊:新的FMVSS 208从2004~2007年实施
ARS第一阶段,智能安全气囊的开发在美国已经法规强制, 欧洲也在市场自愿的情况下采用新技术。 • 侧面安全气囊:侧面柱碰撞试验在欧洲已经在EuroNCAP 中进行评价,而美国则在FMVSS 201中强制实施了与 EuroNCAP相同的侧面柱碰撞要求。2004年颁布的 FMVSS 214的Final Rule中提出的斜向侧面柱碰撞要求 对侧面安全气囊结构影响很大。

解析中国侧面碰撞乘员保护标准
韩玉环 于红秀 孙振东 (中国汽车技术研究中心 )
【摘要 】 我国于 2004年起制定《汽车侧面碰撞的乘员保护 》国家强制性标准 ,并于 2006年 7月 1日在国
内正式实施 。文章详细介绍了该标准内容 ,并分析比较了中 、美 、欧 、日 4方在汽车侧面碰撞法规的差异 。
国认为侧面碰撞对人体伤害最重的是胸部 ,其次 是腰部 ,因而采用了胸部和腰部伤害指标 。对于 胸部伤害指标 TTI,是通过肋骨和脊椎加速度值计 算出来的 ,而腰部伤害指标是通过臀部加速度计 算出来的 。我国的侧面碰撞法规与欧洲相同 ,认 为侧面碰撞对乘员的头部 、胸部 、腹部以及骨盆的 伤害较为重要 ,因而在乘员伤害评定指标中 ,采用 了头部 HPC、胸部 、腹部和骨盆性能指标来评价 。 其中胸部性能指标主要由胸部变形量和粘性指数 评价 ,其具体伤害指标限制如下 : 头部伤害指数 (HPC) ≤1000,胸部变形量 ( RDC) ≤42 mm ,胸部 粘性 指 数 ( VC ) ≤ 1. 0 m / s, 腹 部 力 ( APF ) ≤ 2. 5 kN ,耻骨力 ( PSPF) ≤6 kN。并且对试验车辆 有如下要求 :碰撞过程中车门不许开启 ;碰撞后不 用工具可以打开足够数量的车门 ; 碰撞后燃油泄 漏速度不超过 30 g /m in。
安全气囊对汽车乘员碰撞损伤防护的研究
NANCHANG UNIVERSITY安全气囊对汽车乘员碰撞损伤防护的研究专业:机械工程学号:415914113023学生姓名:张小军2014年9月安全气囊对汽车乘员碰撞损伤防护的研究摘要:概述国内外安全气囊的开发和应用过程中所开展的研究工作。
论述的重点包括事故分析,与安全气囊相关的损伤,损伤生物力学,安全气囊防护有效性的评估方法以及新型安全气囊的研究动态和发展趋势。
关键词:安全气囊;汽车碰撞;损伤防护;损伤生物力学1 介绍安全气囊的防护效果与众多的因素有关。
一方面是事故发生的客观情况,如碰撞强度,碰撞类型,乘员的身高、体重,乘坐位置,车辆的类型和大小等。
另一方面是车辆上安装的防护系统及其使用情况,例如是否使用了安全带和安全气囊及它们的尺寸、容量等。
因而,要对安全气囊有效性做出客观准确的评价,找到影响其防护效果的主要因素难度很大,是安全气囊研究领域的重要问题。
它涉及到工程学、交通事故损伤流行病学、损伤生物力学和统计学等多个学科,是综合性很强的研究领域。
安全气囊依据其作用的不同分为防止前碰撞损伤的驾驶员安全气囊、前座乘客安全气囊和侧面碰撞防护安全气囊等。
安全气囊在防止重大损伤和减少事故死亡的同时,也可能由于它的快速展开而引发新的损伤,本文将此种损伤称为“气囊损伤”。
如何保证安全气囊对各类汽车乘员在各种碰撞条件下提供最有效保护的同时,减少甚至避免气囊损伤,是目前汽车乘员约束系统研究的最主要问题之一。
本文通过对安全气囊防护有效性、气囊损伤和相关技术发展的综述,剖析了这一领域涉及的范围广泛的问题。
2 碰撞事故中的损伤流行病学交通事故损伤流行病学是利用流行病学(Epidemiology)研究的方法和工具研究在道路车辆事故中创伤发生的原因及类型,研究人、环境和工程技术的因素,发展各种方法去评价在交通事故损伤防护过程中所采取的各种降低损伤措施的有效性。
2.1 损伤监测系统与事故数据分析交通事故损伤流行病学研究的基础是可靠的事故数据,这些事故数据应该是经过交通管理部门、医院、保险公司、汽车制造厂和相关权威机构收集得来的。
碰撞标准对比
汽车的安全性是汽车厂商、消费者、政府部门高度关注的问题,而汽车碰撞标准则是检验或评价汽车碰撞安全性能的重要依据,它不但对汽车制造商具有法律上的约束性,而且也能够促进汽车被动安全性能的提高。
国外汽车碰撞标准发展概况目前,国际上实车碰撞试验法规主要有美国的FMVSS和欧盟的ECE两大体系,其他国家的技术法规大多是参照上述两个法规体系制定的。
正面碰撞试验法规为美国的FMVSS 208和欧洲的ECE R94,侧而碰撞试验法规为美国的FMVSS 214和欧洲的ECE R95。
FMVSS 208于1984年颁布,规定1987年以后生产的车型前排必须安装安全气囊;1998年的修订案要求在2002~2005年之间必须安装一种智能化的安全气囊,以保护离位成员和儿童的安全。
FMVSS 214于1973年颁布,当时仅规定了车门静强度试验,对门的力变形特性给予了规定;1990年美国在FMVSS 214车门静强度试验法规中追加了实车碰撞试验方法,并于1993年起分阶段实施。
欧盟于1995年同时颁布正面碰撞试验法规ECE R94和侧面碰撞法规ECE R95。
1998年对正面碰撞法规ECE R94进行修订,将碰撞形态由50km/h带ASD的30度斜角碰撞改为56km/h 的ODB垂直碰撞,进一步提高碰撞安全性要求。
欧洲提高车辆安全性委员会(EEVC)1974年提出了侧碰撞试验方法研究,1989年起草了侧碰撞试验草案,并于1994年5月正式提出侧碰撞法规ECE R95。
日本已颁布实施正面碰撞的安全基准TRAIS11-4-30,并于1997年进行了强化修正,由开始适用的长头轿车扩大到平头型及多用途轿车和小型、微型货车上;扩大了法规约束车型的范围,强化了安全性能要求。
日本在侧碰撞方面的研究起步相对较晚,20世纪90年代初才开始从事这方面的研究,相关法规于1998年正式纳入日本保安基准,其内容等同欧洲ECE R95。
我国汽车碰撞标准制定情况我国于1999年10月28日由原国家机械工业局发布了汽车法规CMVDR 294《汽车正面碰撞乘员保护的设计规则》。

乘用车侧门抗压强度试验操作方法及研究
乘用车侧门抗压强度试验操作方法及研究文章对车辆侧门抗压强度试验操作方法进行了详尽的解读,试验适用于车门静压强度的GB 15743、FMVSS 214、GSO 40等标准,主要针对FMVSS 214等试验设备、试验操作程序及其技术要求等进行分析和讨论,对侧门数型进行优化提供参考,为国产车型完成侧门抗压强度认证提供支持。
标签:侧门;抗压强度试验;FMVSS 214;侧门数型优化1 概述对于汽车车身质量而言,侧门抗压强度是一项非常重要的指标,可以提高汽车的被动安全性。
对于汽车侧门而言,主要是指侧门整体的强度以及车门外板的抗凹刚度两项抗压强度指标。
通常我们所指的整个侧门的挤压强度,都是在准静态试验条件下研究得出的。
侧门结构挤压强度越高,抗压性能越好,车内乘员就越安全。
如果侧门部件的挤压强度低,在遭受外力的强烈挤压时,侧门会发生大的变形和位移,从而伤害车内乘员。
文章以汽车侧门抗压强度为研究对象,讲解侧门抗压强度试验操作方法以及实验分析,为国产车型完成侧门抗压强度认证提供参考和支持。
2 侧门抗压强度试验操作方法2.1 常见侧门抗压强度法规介绍最早制定侧门强度法规的国家是美国,于1973 年颁布了FMVSS 214侧面碰撞乘员保护法规。
目前相关侧门强度的法规有三个:美国机动工程师协会的SAE J367-Passenger Car Door System Crush Test Procedure、FMVSS 214-Side Impact Protection和我国的GB 15743-1995轿车侧门强度法规。
2.2 侧门抗压强度试验基础操作规程2.2.1试验台实验能力试验适用于车门静压强度的GB 15743、FMVSS 214、GSO 40等标准。
2.2.2 检查试验样件检查完试验台后,需要对样件也进行检测。
检查样件的外观状态是否完好,同时根据样件的外观形态需确定好其固定方式,需注意的是整车必须先拆除车轮才能固定进行试验(图1所示)。

碰撞分析实例
1 前部碰撞分析目前前部碰撞主要有两类,一种是正面刚性墙碰撞,如GB 11551、FMVSS 208;另一种是偏置可变形壁障(ODB)碰撞,如ECE 94、IIHS。
尽管这两种试验在试验设置和评价上不尽相同,但其主要目的都是为了使乘员在碰撞事故中得到保护,以及评价车辆结构性能。
车辆结构性能包括转向柱的垂直和向后移动量、燃油系统完整性、在试验过成中车门不应打开、安全带固定点强度、风挡保持力、车上的零件不应侵入乘客箱、发动机盖的后边缘不应通过风挡侵入、碰撞后至少有一个门能打开。
乘员的响应与以下条件有关:车辆的加速度、安全带约束系统、安全气囊约束系统、方向盘与转向柱、防火墙的侵入、膝垫的约束。
由此可见,每个子系统的设计都与乘员有关。
这使得问题很复杂,从设计和分析的观点看很难处理。
于是传统的问题被分成设计与分析子系统,即先保证车辆结构性能,再进行乘员仿真来模拟台车试验。
这里介绍车辆前碰结构性能分析。
通过分析,在合理的精度下,能够预测A柱与转向柱的移动量、防火墙的侵入量、车辆与气囊传感器布置点的加速度波形、能量分布、载荷的传递、特殊的变形模式等。
而燃油系统泄漏、车门的开启性无法直接模拟,只能根据变形情况做初步判断。
1.1.1 正面碰撞建模(1)模型质量匹配前碰分析中,车是运动的,因此车辆模型的质量分布、总质量、质心、轴荷分配是至关重要的,应该与实际状态一致。
但模型是简化过的,其质量要比实际车的轻,质量分布也与实车有差别,为匹配模型的质量,一般采用添加集中质量(mass单元)的方法。
质量单元要均匀分散加在车辆上刚度较大的地方。
如果模型中不包括假人,那么假人的重量也要合理匹配。
(2)定义接触在前碰过程中,车辆中不同的部件、障碍墙、假人会发生自身和相互接触。
因此,要定义接触面来表现这些相互关系。
前碰中一般要定义下列接触:1)将整个车辆定义为一个单一接触面;2)在硬的和软的材料间定义接触面,例如座垫泡沫与结构;3)要监测相互作用的部件,例如轮胎与门槛、燃油箱与周围部件;4)假人与方向盘、仪表板、座椅、安全带、气囊、内饰、结构间的接触面应分开定1义;5)气囊和结构间应定义接触面;6)局部边与边的接触。

在这方面,美国联邦汽车安全标准214(FMVSS214)明确了车辆应遵循的侧向碰撞测试标准,而欧洲则在1991年通过ECE 的《侧面碰撞草案》,并于1995年通过ECER95的正式标准,为该地区的汽车行业奠定了安全基石。
1996年,美国全国公路交通安全局(NHTSA )首次颁布了相关法规,依照FMVSS214的规定对车辆进行了全面的侧向碰撞测试。
从2004年开始,中国启动了有关汽车侧面碰撞乘员保护的国家强制性标准的制定工作。
自2006年7月1日起,这一标准对新型车型进行全面执行,对于在生产中的车型,执行延迟至标准发布后的36个月。
为了进一步评估车辆碰撞安全性,各国纷纷引入新型汽车碰撞安全评估标准,如国家汽车评估计划(NCAP )。
NCAP 是由国家、保险公司、消费者组织和汽车俱乐部等联合倡议的,其评估标准中的碰撞速度通常高于法定要求,更加强调在极端碰撞条件下对车内乘员的损伤评估。
侧面碰撞保护——动态性能要求(FMVSS 214)
侧面碰撞保护—动态性能要求(FMVSS 214)1 前言FMVSS 214法规实施的对象为轿车以及整备质量小于4536kg的多功能乘用车、卡车、公共汽车。
通过对侧面碰撞试验中假人的伤害、车辆侧门强度等规定了车辆防侧面碰撞性能的要求,以减小侧面碰撞对乘员造成严重损伤和致命伤害。
本法规分为三部分,第一部分是关于静态的侧门抗侧向侵入强度试验规范与要求;第二部分为动态的侧面碰撞的实验规范及其乘员保护、车辆结构的要求,此部分法规有了新的修订,新法规于2009年9月1日开始实施;第三部分为侧面撞柱的实验规范及其乘员保护、车辆结构的要求,此部分为FMVSS 214新增的要求,将于2011年9月1日实施。
本文提取了新法规中第二部分的主要内容,第一部分参见《侧面碰撞保护—侧门强度(FMVSS 214)》,第三部分的内容暂未收录。
2 车辆要求2.1 车辆质量试验车辆的质量按以下要求调整:试验车辆质量为其空载车辆质量加上136kg的货物和行李配重,如果该车辆额定的载货质量小于136kg,则按照额定载货质量配重,配重质量的重心应该在规定的行李放置区域。
将车辆放置在水平面上,抽掉燃油箱中所有的燃油,并且启动发动机,直到发动机停止运转,然后向油箱中加注不少于燃油箱容积92%不超过燃油94%的溶剂,供油系统中也应该充满溶剂,溶剂应该有相当于燃油的黏度和密度。
2.2车辆状态“即将交付”状态将车辆置于水平的板上来测定车辆的状态,用同样的水平面和车辆上的同样的标准点来判定车辆的交付状态。
“满载质量”即包括假人和行李配重时的车辆状态。
“试验状态”分别测定以上两种状态的前后、左右与水平面的角度,即纵倾角和侧倾角。
纵倾角为驾驶员处门槛与前排乘客位置门槛所形成的平面与水平面所成的角度。
在车辆前后部分别选取两个在车辆纵向中心面上的点,这两个点所组成的直线与纵向铅锤面所成的角度即为侧倾角。
试验前车辆状态的纵倾角必须为“交付状态”、“满载状态”的纵倾角或两纵倾角中间的某个状态,试验前车辆状态的侧倾角必须为“交付状态”、“满载状态”的侧倾角之一或两侧倾角中间的某个状态。

T ABLE OF CONTENTS (28)SHEETS (29)15. DATA16. FORMS (34)1. PURPOSE AND APPLICATIONThe Office of Vehicle Safety Compliance (OVSC) provides contracted laboratories with Laboratory Test Procedures (TPs) which serve as guidelines for obtaining compliancetest data. The data are used to determine if a specific vehicle or item of motor vehicleequipment meets the minimum performance requirements of the subject Federal Motor Vehicle Safety Standard (FMVSS). The purpose of the OVSC Laboratory TestProcedures is to present a uniform testing and data recording format, and providesuggestions for the use of specific equipment and procedures. Any contractorinterpreting any part of an OVSC Laboratory Test Procedure to be in conflict with aFederal Motor Vehicle Safety Standard or observing any deficiencies in a Laboratory Test Procedure is required to advise the Contracting Officer's Technical Representative(COTR) and resolve the discrepancy prior to the start of compliance testing.Contractors are required to submit a detailed test procedure to the COTR before initiating the compliance test program. The procedure must include a step-by-step description of the methodology to be used.The OVSC Laboratory Test Procedures are not intended to limit or restrain a contractor from developing or utilizing any testing techniques or equipment, which will assist inprocuring the required compliance test data.NOTE:The OVSC Laboratory Test Procedures, prepared for use by independentlaboratories under contract to conduct compliance tests for the OVSC, are notintended to limit the requirements of the applicable FMVSS(s). In some cases, the OVSC Laboratory Test Procedures do not include all of the various FMVSSminimum performance requirements. Sometimes, recognizing applicable testtolerances, the Test Procedures specify test conditions, which are less severe than the minimum requirements of the standards themselves. Therefore, compliance ofa vehicle or item of motor vehicle equipment is not necessarily guaranteed if themanufacturer limits certification tests to those described in the OVSC Laboratory Test Procedures.2. GENERALREQUIREMENTSFMVSS 214, Side Impact Protection, specifies performance requirements for protection of occupants in side impact crashes.The purpose of this standard is to reduce the risk of serious and fatal injury to occupants of passenger cars by specifying strength requirements for side doors. This standardapplies to all PASSENGER CARS as well as 90% of light truck type vehicles with aGVWR < 10,000 lbs, manufactured on and after September 1, 1993, to August 31, 1994.On and after September 1, 1994, all light truck type vehicles with a GVWR < 10,000 lbs will be required to meet the static requirements.3. SECURITYThe contractor shall provide appropriate security measures to protect the OVSC testvehicles from unauthorized personnel during the entire compliance-testing program. The contractor is financially responsible for any acts of theft and/or vandalism, which occurduring the storage of test vehicles. Any security problems, which arise, shall be reported by telephone to the Industrial Property Manager (IPM), Office of Contracts andProcurement, within two working days after the incident. A letter containing specificdetails of the security problem will be sent to the IPM (with copy to the COTR) within 48 hours. The contractor shall protect and segregate the data that evolves from compliance testing before and after each vehicle test. No information concerning the vehicle safety compliance-testing program shall be released to anyone except the COTR, unlessspecifically authorized by the COTR or the COTR's Branch or Division Chief. The tested vehicles shall be protected from the elements, shall be retained by the test contractor fora MINIMUM of 60 days so that NHTSA and vehicle manufacturer personnel can be givenan inspection opportunity.NO INDIVIDUALS, OTHER THAN CONTRACTOR PERSONNEL DIRECTLYINVOLVED IN THE COMPLIANCE TESTING PROGRAM, SHALL BE ALLOWED TO WITNESS ANY VEHICLE COMPLIANCE TEST UNLESS SPECIFICALLYAUTHORIZED BY THE COTR.4. GOODHOUSEKEEPINGContractors shall maintain the entire vehicle compliance testing area, test fixtures andinstrumentation in a neat, clean and painted condition with test instruments arranged in an orderly manner consistent with good test laboratory housekeeping practices.5.

COMPLIANCE TEST EXECUTIONTEST EQUIPMENT DESCRIPTIONFollowing is a list of the minimum test equipment needed to evaluate the minimumperformance requirements as outlined in FMVSS 214.A. Static Loading Device - The loading device will consist of a rigid, steel cylinder orsemi-cylinder 12.0 inches, + 0.25 inches, - 0 inches in diameter with an edgeradius of 0.500 inch. The surface should be continuous and smooth. The lengthof the loading device shall be such that when the bottom of the device is placedalong a line 5 inches above the lowest point of the door the top surface of theloading device is (for vehicles with windows) at least one-half inch above theedge of the door window opening but not of a length that will cause contact withany structure above the bottom edge of the door window opening during the test.For doors without windows, the top surface of the loading device should be thesame height above the ground as when the loading device is positioned for thefront door of that vehicle with a window (see Figure 5). The load may be appliedeither mechanically or hydraulically.INWARD LOADING ON REAR DOUBLE SIDE DOORS WITHOUT WINDOWSFIGURE 5B. Vehicle Tie-Down Fixture - The vehicle must be secured on a rigid, horizontalfixture (± 0.250º) so that it is adequately restrained at the vehicle underbody andalso at the sides to prevent lateral and/or rotational movement of the whole vehicleduring the test. Good engineering judgement will be required to provide maximumsupport, for the maximum area possible outside the centerlines of the two axles.Following are some examples of different types of vehicle construction that may beencountered:(1) Separate body and frame construction(2) Full unit body construction(3) Unit body construction and stub frame constructionThe vehicle shall be secured to the loading fixture using wire rope, turnbuckles,strap plates, etc. As many horizontal and vertical tie-downs will be used asneeded to prevent movement under load. The tie-downs will be placed at orforward of the front wheel lateral centerline and at or rearward of the rear wheellateral centerline. In some instances, such as when testing some pick-up truckconfigurations, the vehicle may need additional tie-downs somewhere between thefront and rear wheel lateral centerlines. This will ensure that the vehicle is secureand will not move during testing. The COTR will make the final determination ofvehicle tie down placements.C. Load Measuring Device - Two independent load cells of proper capacity(see Section 13(A)(3)) with an accuracy of ± 0.250 percent, shall be used formeasuring load and will be placed in the loading system so that they measure theactual load being transmitted into the vehicle door.D.
