The work of preparing Internati

17、onal Standards is normallycarried out through ISO technical committees. Each member bodyinterestedin a subject forwhich a technical committee has beenestablished hasthe right to be represented on thatcommittee. International organizations, governmental and non-governmental, in liaison with ISO,also

18、take part in the work. ISO collaborates closelywith the International Electrotechnical Commission (IEC) on all mattersofelectrotechnical standardization. International Standards aredrafted in accordance with the rules given in the ISO/IEC Directives, Part2.The main taskoftechnical committees is to p

19、repare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requiresapproval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibilitythat s

20、ome ofthe elements of this document maybethe subject of patent rights.ISO shall not be held responsible for identifying any or all such patent rights. ISO 10605 was prepared byTechnical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electricaland electronic equipment. This second edition can

ISO 2010BS ISO 10605:2008+A1:2014 ISO 10605:2008+A1:2014 (E)vIntroduction The familiar electrostatic dis charge, due to former charge build-ups generated, forexample, when moving about inside a vehicle orgetting ou

22、t of it, has assumed greater significance with the increase of vehicle electronic modules.Tests simulatingthe electrostaticdischarge of humans, in common use by various industries, were examined and it was determined that theywere not fullyapplicable to the automotive environment. As a consequence,

23、teststailoredto the automotive environment were developed. Teststhat simulate an electrostatic discharge (ESD) into a vehicle electricalsystemare based on the human ESDmodel. Sensitive electrical devices can be adversely affected by energy either coupled or radiated fromelectrostatic discharges. Thi

24、s International Standard describes ESD tests that are applicable to both automotive electronic modules and vehicles.

25、rnational Standard specifies the electrostatic discharge (ESD) testmethods necessary to evaluate electronic modules intended for vehicle use. It applies to discharges in the following cases: ESD in assembly; ESD caused by servicestaff; ESD caused by occupants.ESD applied to the device under test(DUT

26、)can directlyinfluence the DUT. ESD applied to neighbouring parts can couple into supply and signal linesofthe DUT in the vehicle and/or directlyinto the DUT. This International Standard describes testprocedures forevaluating both e lectronic modules on the benchand complete vehicles. This Internati

27、onal Standard applies to all typesofroad vehiclesregardlessofthe propulsion system (e.g. spark-ignition engine, diesel engine, electric motor).This International Standardisbased in part on IEC 61000-4-2 and describes vehicle-specific requirements.This International Standarddoes not applyto pyrotechn
