Road vehicles — Test methods for electrical disturbances from electrostatic discharge
1 Scope
This International Standard specifies electrostatic discharge (ESD) test methods for evaluating electronic modules intended for use in road vehicles, including procedures for evaluating electronic modules both on the bench and in completed vehicles. Additionally, it specifies a test procedure for classifying the ESD sensitivity of modules for packaging and handling, and a procedure for calibrating the simulator used to generate the electrostatic discharges, as well as functional status classifications for immunity to ESD.
This International Standard is applicable to all types of road vehicles, regardless of the vehicle propulsion system (e.g. spark-ignition engine, diesel engine, electric motor).

4 Test equipment
4.1 General
Test equipment used to verify the requirements of the device under test shall not be sensitive to ESD.
The following test equipment is applicable to all test procedures specified in this International Standard, including those of annex A.

4.2 ESD simulator
The ESD simulator shall have the following characteristics.
a) Voltage range: variable from ? 25 kV to + 25 kV.
b) Capacitance: 330 pF ± 10 %, 150 pF ± 10 % (two probes).
c) Resistance: 2 000 ? ± 10 %.
d) Risetime:
1) direct contact, 0,7 ns to 1 ns (at a 2 ? load);
2) air discharge, u 5 ns (at a 2 ? load);
3) tip shapes (see Figure 2), in accordance with IEC 61000-4-2.
The simulator shall be designed so that the discharge capacitance is fully charged to the desired voltage before the energy is switched to the device under test.
The construction of the ESD simulator shall be such that the high-voltage ground and the chassis ground are
electrically isolated from one another.
Simulator equipment used shall be of a type that is commercially available.
4.3 Ground plane
A ground plane is a metallic sheet (copper, brass, etc.3)) that shall have a minimum thickness of 1 mm and an area of at least 1 m2, ensuring that it projects beyond the device under test by at least 100 mm on all sides. The ground plane shall be connected to the facility ground by a ground strap less than 2 m long and at least 50 mm wide.
4.4 Insulation blocks
Insulation blocks, if used, shall be constructed of clean, non-hygroscopic material. The blocks shall be
(25 ± 2,5) mm in height and project beyond the device under test by at least 20 mm on all sides.
4.5 Coaxial target
A coaxial target as specified in IEC 61000-4-2:1995 shall be used during the ESD simulator verification given in annex A.
4.6 Wideband attenuator
If needed, a 50 ?, 20 dB wideband attenuator is to be attached to the output of the coaxial target during the ESD simulator verification given in annex A.500) {this.resized=true; this.width=500; this.alt='這是一張縮略圖,點擊可放大。\n按住CTRL,滾動鼠標滾輪可自由縮放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/55/1402091184890422.jpg');}" onmousewheel="return imgzoom(this);">
