USCAR20线束接插件实验标准

1.5为了能够适应特殊要求，允许对本试验的条件和程序进行修改。但是该修改与相应的关联性不相关， 这些修改必须记录在测试报告中。 1.6 This procedure is valid for USCAR/EWCAP classes 1,2, and 3. Correlation has not been established for class 4. Although class 1and 2 terminals may not be designed for continuous use at 125oC, conditioning at higher temperatures as directed in this procedure is necessary to properly accelerate aging. 1.6本程序对USCAR/EWCAP的1、2、3类型是有效的。但没有建立类型4的相关联试验。虽然类型1和类 型2端子并不是用于125° C的工作环境中，但是为了加快样品老化允许施加更高的温度。 2.

SAMPLES 4.样品 4.1 The minimum sample size is 30 terminal pairs and 4 connector assemblies per base temperature and connection type. This normally requires a minimum of 33 terminated leads for each gender and temperature to be tested. Three samples are used for deduct measurements of each gender. Deduct samples will not be subjected to any conditioning. 4.1对于每一个基本温度条件，至少30对端子和4只连接器组件。对于每一种端子组件（端子和导线）和 温度通常需要33只端子组件。 4.2 Make terminated lead samples a minimum of 150 mm in length (ref.

Individual samples should be uniquely identified in a fashion suitable to the environmental conditioning that they will experience. 4.3申请者递交样品的时候，应该对样品标上标志如零件号、日期、修订字母等一些描述性的内容。根据 试验要求对每一个样品进行唯一性地标志。 5. EQUIPMENT 5.设备 5.1 Dry Circuit Resistance - Dry circuit conditions require that the maximum voltage impressed across the test sample be limited to 20 millivolts and the maximum current through the sample be limited to 100 milliamperes. Measure resistances with a Microohmmeter capable of satisfying the dry circuit conditions specified. The micro-ohmmeter must limit the open circuit voltage to 20 mV, limit the current applied to 100 mA, and use either offset compensation or current reversal methods to measure resistance. The 4-wire (Kelvin) connection method shall be used. 5.1干电路电阻-干电路电阻的条件是： 施加在样品上的电压最大值20mV， 流过样品的电流最大值100mA。 满足该干电路条件的毫欧计测量电阻。毫欧计必须限制最大开路电压20 mV，最大电流100 mA，利用偏 移补偿和电流反向的方法来测量电阻。用4线法（即电压电流法）来测量电阻。 5.2 Thermal Aging - the test chamber shall be capable of maintaining the specified temperature within ± 3° C throughout the area where the components are placed.

FIELD CORRELATED LIFE TEST SUPPLEMENT TO SAE/USCAR-2 ***WARNING*** No electrical terminal may be represented as having met this USCAR/EWCAP specification unless conformance to all applicable requirements of this document have been verified and documented. At least the minimum applicable sample size set forth in each test must have been tested with no sample in the entire group tested failing to meet all applicable Acceptance Criteria for that test. All required verification and documentation must be done by the supplier of the part or parts. If testing is performed by another source, it does not relieve the primary supplier of responsibility for documentation of all test results and for verification that all samples tested met all applicable Acceptance Criteria. ***警告*** 只有产品符合本规范的全部要求时才认为产品是满足USCAR/EWCAP。每一个试验都有最小样品量要 求，并且所有这些样品都要求满足相应的接收标准。供应商应该验证零件符合性并且记录结果。假如是 有第三方来做试验，这不能减少供应商验证零件符合性和记录结果的责任。 1. SCOPE 1.范围 1.1 This life test for underhood/passenger/trunk connector systems may be used in place of Section 5.8.6 (Connector System Electrical Test Flow Chart) of SAE/USCAR-2. All other requirements of SAE/USCAR-2 remain applicable even when this test is used. Refer to SAE/USCAR-2 and Connector/Terminal Supplier for appropriate power rating and current cycle Testing. 1.1用于underhood/passenger/trunk连接器系统的寿命试验可能取代SAE/USCAR-2中的第5.8.6段试验 （连接器系统电性能试验流程图） 。 即使本试验取代了SAE/USCAR-2中的第5.8.6段试验， SAE/USCAR-2 其余的试验仍然适用。参考SAE/USCAR-2和连接器/端子合适的电源额定值和电流循环试验。 1.2 When this life test is used in place of para. 5.8.6 of USCAR-2, complete Para 5.6.1 (Thermal Shock) of SAE/USCAR-2 in it’s entirety in order to demonstrate capability to withstand the 10-cycle service (mate/un-mate) requirement. 1.2当本试验取代了SAE/USCAR-2中的第5.8.6部分试验， 完整地执行SAE/USCAR-2第5.6.1段的试验 （热 冲击试验），这是为了证明产品能够承受10个循环服务要求（插/拔） 1.3 This test specification details the procedure for testing the performance of electrical connections to a test sequence (FCLT – Field Correlated Life Test) that has been correlated to automotive vehicle conditions. The correlation applies to crimps and interfaces used in automotive applications and has been established with thousands of samples and millions of product and vehicle environmental measurements. The testing is performed with mated connector assemblies. In general, testing of connections at two base temperatures, 85° C and 125° C, through two cycles of the FCLT has been shown to correlate to at least 150,000 miles (240,000 kilometers). See Reference Documentation section for qwenku.baidu.comestions regarding correlation issues. 1.3本规范详细描述了关于电连接性能的程序，模拟汽车实际条件进行一系列寿命试验。建立了汽车实际 情况中压接界面和连接界面与该试验的相关性并且建立了数千样品和数百万产品和汽车环境测量。用于 该试验的是插配好的连接器组件。一般，本试验在85° C 和125° C温度下进行2个循环，这等价汽车行使 了150,000 miles(240,000 kilometers)。参考相关性问题的参考文件。 1.4 This test shall be performed a minimum of two times using separate sample sets, once at a base temperature of 85oC and once at a base temperature of 125oC. The base temperature is the temperature to be used in the thermal aging conditioning steps and as the upper temperature in thermal shock conditioning steps. 1.4本试验至少要用两组样品分别进行一次试验。 一次是在85° C下进行试验， 一次是在125° C下进行试验。 这两个基本温度是作为热老化试验的温度，是进行热冲击试验的温度上限。 1.5 Modification to tests and conditioning procedures contained in this document may be made to accommodate special situations. However, no field correlation can be associated to these modifications. Such modifications shall be fully documented in the test report.
