\nRoad Vehicles – Electrical Disturbances from Conduction and Coupling – Part 3: Electrical Transient Transmission by Capacitive and Inductive Coupling via Lines Other Than Supply Lines<\/p>\n
\n1 SCOPE<\/p>\n
This Part of GB\/T 21437 establishes a bench test method 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.
\nThree test methods are described in this Part:
\n\uf0be the capacitive coupling clamp (CCC) method;
\n\uf0be the direct capacitive coupling (DCC) method;
\n\uf0be the inductive coupling clamp (ICC) method.
\nNote: The applicability of the three test methods is shown in Table 1.
\nOnly one test method need be selected for slow transients and only one method need be selected for fast transients.
\nThis Part applies to road vehicles fitted with nominal 12V, 24V or 42V electrical systems.
\nFor transient immunity, Annex B provides the recommended test severity levels in line with the functional performance status classification (FPSC ) principle described in GB\/T 21437.1.<\/p>\n
