21、ssumed greater significance with the increase of vehicle electronic modules. Tests simulating the electrostatic discharge of humans, in common use by various industries, were examined and it was determined that they were not fully applicable to the automotive environment. As a consequence, tests tai
22、lored to the automotive environment were developed.Tests that simulate an electrostatic discharge (ESD) into a vehicle electrical system are based on the human ESD model. Sensitive electrical devices can be adversely affected by energy either coupled or radiated from electrostatic discharges.This do
23、cument describes ESD tests that are applicable to both automotive electronic modules and vehicles.INTERNATIONAL STANDARDISO 10605:2023(E)Road vehicles Test methods for electrical disturbances from electrostatic discharge ScopeThis document specifies the electrostatic discharge (ESD) test methods nec
24、essary to evaluate electronic modules intended for vehicle use. It applies to discharges in the following cases: ESD in assembly; ESD caused by service staff; ESD caused by occupants.This document describes test procedures for evaluating both electronic modules on the bench and complete vehicles. Th
25、is document applies to all types of road vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor).The test for electronic modules on the bench described in this document applies to any DUT (powered by an unshielded power system, DUT powered by a shield
26、ed power system, self-powered DUT, etc.).This document does not apply to pyrotechnic modules.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Suggested test levels are included in AnneX C.Standard test conditions shall be as follows: ambient temperature: (25 10) ; relative humidity between 20 % and 60 %.If other values are agreed to by the users, these values shall be documented in the test report.5 Test locationShielded enclosures or e
36、ven absorber-lined shielded enclosures are allowed but not required.NOTE ESD testing creates transient fields, which can interfere with sensitive electronic devices or receivers, even at a distance of a few meters. It is advisable that this be considered when choosing a test location.6 Test apparatu

40、undled) with the ESD generator discharge return cable, unintended current can flow through this (these) cable(s).The ESD generator should be able to generate a repetition rate of at least 20 discharges per second down to manual control without any degradation of the discharge current waveform.The ti
41、p voltage should be checked continuously by the generator internal tip voltage supervision.For contact discharge a grounded discharge resistor with 1 MQ 20 % resistance from tip to ground is recommended and prevents pre-pulse-voltage occurrence which can lead to non-reproducible test results; proper
42、 fixing of resistor shall not change the current shape.In cases where a 2 m length of the discharge return cable is insufficient (e.g. for tall DUTs, a length not exceeding 3 m may be used and compliance with the waveform specifications shall be guaranteed (e.g. by the manufacturer or from calibrati
