Foreword

GB/T 33014 "Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy" consists of the following parts.

- Part 1: General;

- Part 2: Absorber-lined shielded enclosure;

- Part 3: Transverse electromagnetic (TEM) cell;

- Part 4: Bulk current injection (BCI);

- Part 5: Stripeline;

- Part 7: Direct radio frequency (RF) power injection;

- Part 8: Magnetic field immunity;

- Part 9: Portable transmitter simulation;

- Part 10: Conduction immunity method for extended audio range;

- Part 11: Reverberation chamber.

This Part is Part 2 of GB/T33014.

This Part is drafted in accordance with the rules given in GB/T 1.1-2009.

This Part uses the re-drafting method to modify and adopt ISO 11452-2:2004 "Road vehicles - Component test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 2: Absorber-lined shielded enclosure".

The technical differences between this Part and ISO 11452-2:2004 are as follows.

- PREPARE Clause 1 according to the provisions of GB/T 1.1-2009;

- MOVE the content ("the following standard test conditions...") in the original international standard not suitable for Clause 1 TO Clause 4 "Test conditions".

- REPLACE the reference standard ISO 11452-1 WITH GB/T 33014.1-2016 modifying and adopting ISO 11452-1:2005.

- For consistency in understanding and presentation with Part 1, I, II, III, IV, V of Table C.1 are changed to L1, L2, etc., and I, II, III, etc. are understood as state I, II, III, etc. The following editorial changes have been made in this Part.

- DELETE the foreword and introduction of the original international standard.

- For consistency with other standards, a note "See GB/T 33014.1-2016 for a detailed explanation of FPSC." is added in Annex C.

3 Terms and definitions

For the purpose of this document, the terms and definitions defined in GB/T 33014.1-2016 apply.

4 Test conditions

The applicable frequency range of the absorber-lined shielded enclosure test method is 80 MHz to 18 GHz. The user shall specify the test severity level(s) over the frequency range. Suggested test levels are shown in Annex C.

5 Test location

The tests shall be performed in an absorber-lined shielded enclosure (simulated open field).

6 Test apparatus and instrumentation

The DUT shall be operated as required in the test plan by actuators that have a minimum effect on the electromagnetic characteristics, e.g. plastic blocks on the push-buttons, pneumatic actuators (with plastic tubes for air supply piping).

Connections to equipment monitoring electromagnetic interference reactions of the DUT may be accomplished by using fibre-optics, or high-resistance leads. Other types of lead may be used but require extreme care to minimize interactions. The orientation, length and location of such leads shall be carefully documented to ensure repeatability of test results.

7 Test set-up

The DUT shall be placed on a non-conductive, low relative permittivity (dielectric-constant) material (epsilon r <= 1.4), at (50 ± 5) mm above the ground plane. The case of the DUT shall not be grounded to the ground plane unless it is intended to simulate the actual vehicle configuration. The face of the DUT shall be located at a distance of (200 ± 10) mm from the edge of the ground plane.

8 Test method

The DUT shall be made to operate under typical loading and other conditions as in the vehicle. These operating conditions shall be clearly defined in the test plan to ensure supplier and customer are performing identical tests.

The test shall be performed with the substitution method, which is based upon the use of forward power as the reference parameter used for field calibration and test. This method is carried out in two phases. […]
