The component shall pass the Design Validation and Product Validation environmentaland durability requirements of GMW3172. These requirements shall be clearly identifiedthrough use of the GMW3172 Coding System resulting from the location of the product in thevehicle. The code for this product is _. A product reliability of at least 97%, witha statistical confidence of 50%, shall be demonstrated on test as described within GMW3172 for product subjected to a combination of vibration and thermally induced fatigue. Thedemonstration of 97% Reliability on-Test corresponds to a field reliability of 99.5% under theassumption of a Customer Variability Ratio of three. The Test Flows identified in GMW3172must be followed with any exception receiving prior approval before establishing the ADV plan.The supplier must attain world-class reliability for this product. The test requirements contained in this document are necessary but may not be sufficient to meet this world-class field reliability requirement. The supplier is responsible for assuring that other actions are taken such that world class field reliability requirements are met.”在GMW3172中分析、开发、验证被强制要求执行是为了确保最终产品的成熟。零部件就通过GMW3172的设计验证、制程验证和环境及耐久规范。这些要求应被清楚的定义通过产品在车身位置的编码系统。产品的编码是： 。产品的可靠性最少97%，在统计的50%，应被证明象在GMW3172中描述的复合振动和热疲劳条件。The requirement code for this product must be clearly assigned in the CTS or SSTS. Supplementaltesting for failure mechanisms not covered by GMW3172 must be specified in addition to GMW3172.Durability is defined as the lifetime-duty-cycle-use that exercises failure mechanisms other than vibration and thermally induced fatigue (mechanical functions for example).这个产品的编码一定清楚的写在CTS或SSTS里。追加失效机械试验没有被GMW3172复盖必须加入GMW3172。耐久被定义为寿命-功能-周期-使用其他的机械装置Operating Types as noted in table 8 apply during the test activities described undereach of the above noted sections每段试验如表8所示，1.3 How GMW3172 Integrates into the Supplier ADV ProcessFigure 3 Integration Into The Supplier ADV Process 进入供应商验证流程1.4 GMW3172 A/D/V Task ChecklistsDefinitions:M - Mandatory For Electronic ModulesR - Recommended - Shall be conducted but may be waived only by GM under special circumstancesC - Conditional Task based on presence of feature, technology, risk, or vehicle location.M/C - Mandatory when condition or design feature existsM-对于电子的组件是强制性的R- 推荐 -被引用但是只可能被在特别的情况下面的 被GM 免除C-以特征，技术，危险或车辆位置的出现为基础的有条件的工作。M/ C- 强制性的当条件或设计要求存在的时候GMW3172 A/D/V Task Checklist Establishment of RequirementSubjectRecommendedThisProgramReliability Required by This Program The sample sizes and test durations shown on the example test flows relate to a“reliability on test” of 97% with 50% confidence. This“reliability on test” value corresponds to” reliability in the field” of 99.5% for 100,000 miles or 10 years. The value of 50% confidence is used in the sample size and test durationcalculation. The relationship of confidence and reliability should be expressed as follows: “I am 50% sure that the reliability is at least 97% as demonstrated on this test”. When the lifetime or reliability requirement is different from above, the sample sizes and test durations must be adjusted for those failure mechanisms using the success-run demonstration method. No increase in sample size is necessary for vibration when the stepped-stress method of Appendix “B” is used, however, a longer target life value should be used depending on the VTS. Truck usage is sometimes noted as 10 years and 200,000 miles. The following adjustments should be made for this longer life requirement: Truck Vibration Use the longer calibratedtest time as described in the text. This test timewill be a function of the “Miles” requirement inthe VTS Truck No adjustments are necessary for anyother tests这个项目的可靠性要求：样品的数量和测试期间列在这个试验流程例子，涉及到97%的测试可靠性和50%的信任。可靠性试验的评价应符合可靠性99.5%可达到100，000米或10年。50%的价值被用于计算样品数量和测试期间。这信赖性和可靠性将被明确：我是 50% 确信那可信度至少是如这一个测试所示范的 97%，当寿命与可靠性要求不一致，应调整样本容量和测试期间，应用成功的验证方法，和调整失败的机构。当附件B中的后要试验步骤被应用，振动试验不增加样本数量是有必要的。无论如何长寿命应用于TVS。卡车的寿命通常是10年200000米。卡车-GMW3172 A/D/V Task Checklist ANALYTICAL ProceduElectrical Loads Analysis (SABER/SPICE) 电负荷分析（SABER/SPICE）E/E Circuit Performance AnalysisE/E回路性能分析Recommended建议ThisProgramNominal Performance Analysis表面分析MShort/Open Circuit Analysis短路/开路分析CElectrical Interface Models接口模型MMechanical And Thermal Loads Analysis机械和热性能分析Circuit Board Resonant Frequency and Displacement Analysis Resonant Frequency=电路板频率和移位分析共鸣频率=RThermal Fatigue Analysis: Identify risk when using surface mount technology to join large elements with significantly different coefficients of thermal expansion耐热性分析：当把大的元件使用表面装配技术和不同的而重要的元件连接时，要确定风险系数CSnap Lock Fastener Analysis: Ensure that the elastic limit is notexceeded when snapfit attachments are maximally stressed during assembly (Worksheet in Appendix A)弹簧锁按钮分析：当用最大力按按钮时，保证不会超过弹性形变（附录一）M/CCrush Test Analysis: Identify clearance to components when loaded with either a human elbow or foot耐压实验：要识别清楚是人的肘部还是脚部施压RLead-Free Solder Checklist无导线焊接检查表M/CReliability Design Review #2 AnalysisWhat design margins are known and what should be learned during development可信度设计研讨#2-分析在开发过程中，因该设计极限和那些东西需要掌握Date = _GMW3172 A/D/V Task Checklist DEVELOPMENT Procedures.Electrical Performance Development/Evaluation Procedures性能开发/评估过程RecommendedThisProgCircuit Performance at Room Temperature室温下的电路性能ROver/Under Voltage, Jump Start and Reverse voltage Evaluation过/欠电压，跳变和反向电压评估RShort Circuit Evaluation短路评估MFlash Programming Sensitivity to Ground Lead Inductance闪光器接地线设计灵敏度参数M/CElectromagnetic Compatibility (EMC) Development GMW3100电磁兼容性的开发-GMW3100MMechanical And Climatic Loads Development/Evaluation Procedures机械和环境上的开发/评估过程Crush Resistance of the case of the device设备的抗压性RFree Fall Endurance Development自由落下时的耐久性Ruggedization Development for Vibration and Temperature HALTper GMW8287 (1-2 days only)Performance at and below the minimum temperature requirement assess design marginPerformance at and above the maximum temperature requirement assess design marginSensitivity to broadband random vibration at and above the requirement assess design margin*Note: Required for electronic devices but should beconsidered optional for simple Buss Electrical Centers振动和温度耐久性-HALT每个GMW8287（只有1-2天）满足在最小温度或低于最低温度的性能-评定设计满足在最高温度或高于最高温度的性能-评定设计频率带宽的随机的震动要满足或高于要求-评定设计注意：电子设备需要，但是要考虑的一般的中央接触器R/M*Sensitivity to Extended Humidity HAST per JEDEC STD 22-A110 for 48 hours长久耐湿性-HAST per JEDEC STD 22-A110 48小时 Cst Test for Moisture Susceptibility (1/2 day)受潮st测试，12小时RLocalized Circuit Board Over-Heating Using Thermal Couple Method Or Infrared Imaging Method局部电路板过热应用热偶或红外线成像方法CReliability Design Review #3 DRBTR during DevelopmentHow well have we reacted to what we have learned and what risks remain going into Validation可信度设计平价#3-DRBTR 开发过程中我们要知道我们所学的东西和所面临的风险Date = _RGMW3172 A/D/V Task Checklist DESIGN VALIDATION ProceduresUse the following task checklist in conjunction with the test flows. “Stars” are used in the test flows todenote points where the product must be evaluated for degradation or loss of function.

Design iterations should occur during the Analysis and Development portions of the ADV process, and possibly during Design Validation. The intent of Product Validation is to detect for possible significant degradation that may result from changes in tooling, processing, or last minute changes following Design Validation. Product Validation is not intended to be a second iteration of Design Validation and is not intended to quantify variability resulting from manufacturing variation.注意：产品确认，假定产品在分析和开发中是可靠的并且可靠性和性能满足需求标准。重复设计应该在ADV分析和开发过程中，或者在设计确认过程中。产品确定的目的是为了发现由于工具，生产或者以下流程的变化引起的重大事故。产品确定的目的并不是设计的再次重复也不是由于机械变化引起的质量变化。Product Validation Other tests may be added if significantuncertainty still exists from Design ValidationRecommendedProgramVibration - Success-Run Vibration Test or Stepped-Stress Vibration Test To Failure both with superimposed thermal cycling.

These product characteristics must be controlled in production (KPC). Additionally, theseweaknesses should direct the type and extent of screening to be conducted during startup and production可信度设计最后评价#5产品确认尽管产品已被确认，但是最后的设计审核必须明确在生产和实验错误中最敏感的产品特性。这些产品特性必须在生产过程中被控制（KPC）。此外，这些错误在开始和生产过程中，应被指明类型和范围。MDate = _MFill out a Design Validation Checklist for tests that have to be repeated.对于那些需要重复的还要填写一个设计明确表格1.5 Coding Designation By Location In The VehicleThis document distinguishes between the following mounting locations and defines the minimumElectrical, Mechanical, Thermal, Climatic, Chemical, Water and Dust Protection requirements. Othermounting locations are possible. The set of requirements can be created by a new code lettercombination as described in Section 2 (Quoting Requirements).这个文件说明了下列仪器位置和最小电气的，机械的，温度的，环境的，耐水和耐尘方面的要求。其他的架设位置是可以的。要求可以被描述成一个新的代码，像第二接那样（引用需求）。1.6 Code Letter For Electrical LoadsThe following table defines the 12 V systems nominal, steady state voltage range and minimum andmaximum test voltage as measured at the E/E device. The table should also be used in specifying theE/E device criteria requirements unless otherwise specified in the CTS.下列表格定义了12V系统标准，稳态电压范围，最大最小测试电压像E/E设备测量那样。除非在CTS中另有说明，要不该表格也应该用于描述E/E设备要求。For 42 V vehicle electrical systems, see ISO 21848-2, “Road Vehicles Electrical and Electronicquipment for a 42 V Network Part 2: Electrical Loads”对于42V的供电系统参照ISO 21848-2，“Road Vehicles Electrical and Electronicquipment for a 42 V Network Part 2: Electrical Loads”Definition of Steady State Voltage: Any voltage application that will occur for more than 2 minutes.稳太电压：持续产生2分钟以上的电压How to Use This Table: Identify the columns that span the range of steady state supply voltageprovided to this device.
