ISO 7637-3:20 07建立了一个台式测试，用于评估被测器件（DUT）通过经由电源线以外的线路耦合对瞬态传输的抗扰度。测试瞬态脉冲模拟快速和慢速瞬态干扰，例如由感性负载的切换和继电器触点弹跳引起的干扰。ISO 7637-3:20 07中描述了三种测试方法:电容耦合钳位（CCC）方法；直接电容耦合（DCC）方法；和电感耦合钳位（ICC）方法。对于慢瞬态只需要选择一种测试方法，对于快瞬态只需要选择一种方法。ISO 7637-3:20 07适用于装有标称12 V、24 V或42 V电气系统的道路车辆。对于瞬时抗扰度，附录B根据ISO 7637-1中描述的功能性能状态分类（FPSC）原则提供了推荐的测试严重程度。

ISO 7637-3:2007 establishes a bench top test for the evaluation of the immunity of devices under test (DUTs) to transient transmission by coupling via lines other than supply lines. The test transient pulses simulate both fast and slow transient disturbances, such as those caused by the switching of inductive loads and relay contact bounce.Three test methods are described in ISO 7637-3:2007:

• the capacitive coupling clamp (CCC) method;
• the direct capacitive coupling (DCC) method; and
• the inductive coupling clamp (ICC) method.

Only one test method need be selected for slow transients and only one method need be selected for fast transients.ISO 7637-3:2007 applies to road vehicles fitted with nominal 12 V, 24 V or 42 V electrical systems.For transient immunity, Annex B provides recommended test severity levels in line with the functional performance status classification (FPSC) principle described in ISO 7637-1.
