BS ISO 7637-3:2016定义了评估被测设备（DUT）抗扰度的台架试验方法 与电源线以外的线路耦合的瞬态脉冲。测试脉冲模拟快速和慢速 由电感负载切换和继电器触点弹跳引起的瞬态干扰。ISO 7637本部分描述了以下三种试验方法:电容耦合钳（CCC）法；直接电容耦合（DCC）法；电感耦合钳（ICC）法。ISO 7637的本部分适用于装有标称12 V或24 V电气系统的道路车辆。 对于瞬态脉冲抗扰度，附录B提供了符合 ISO 7637-1中描述的功能性能状态分类（FPSC）原则。交叉引用:ISO 7637-1ISO 7637-2ISO 11452-4购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS ISO 7637-3:2016 defines bench test methods to evaluate the immunity of devices under test (DUTs) to transient pulses coupled to lines other than supply lines. The test pulses simulate both fast and slow transient disturbances caused by the switching of inductive loads and relay contact bounce.The following three test methods are described in this part of ISO 7637:capacitive coupling clamp (CCC) method;direct capacitive coupling (DCC) method;inductive coupling clamp (ICC) method.This part of ISO 7637 applies to road vehicles fitted with nominal 12 V or 24 V electrical systems. For transient pulses immunity, Annex B provides recommended test severity levels in line with the functional performance status classification (FPSC) principle described in ISO 7637-1.Cross References:ISO 7637-1ISO 7637-2ISO 11452-4All current amendments available at time of purchase are included with the purchase of this document.
