GB/T 33012.2-2016Road vehicles -- Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy -- Part 2: Off-vehicle radiation sources (English PDF)

Foreword

GB/T 33012 "Road vehicles - Vehicle test methods for electrical disturbances from

narrowband radiated electromagnetic energy" consists of four parts.

- Part 1.General;

- Part 2.Off-vehicle radiation sources;

- Part 3.On-board transmitter simulation;

- Part 4.Bulk current injection (BCI).

This Part is Part 2 of GB/T 33012.

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

This Part uses the re-drafting method to amend and adopt ISO 11451-2.2005 "Road

vehicles - Vehicle test methods for electrical disturbances from narrowband radiated

electromagnetic energy - Part 1.Off-vehicle radiation sources".

Technical differences between this Part and ISO 11451-1.2005 and the causes are as

follows.

- Clause 1 is normatively prepared according to the specifications of GB/T 1.1-2009;

- The normative reference ISO 11451-1.2001 is modified to GB/T 33012.1-2016

adopting ISO 11451-1.2005;

- In order to achieve the same understanding and presentation with Part 1, I, II, III,

IV, V of Table A.1 are modified to L1, L2, etc., and I, II, III, etc. are understood as

state I, II, III, etc.;

- To be consistent with other parts, the structure of Clause 6 is adjusted.

This Part also makes the following editorial modifications.

- The content which is not suitable for the emergence in Clause 1 (The

electromagnetic disturbances are limited to narrowband electromagnetic fields.)

in the original international standard is moved to Clause 4 "Test conditions";

- "a) Vertical polarization" and "b) Horizontal polarization" in "Figure 1 Example of

absorber-lined shielded enclosure" of the original international standard are

editorial errors, which are modified as "a) Front view" and "b) Top view" in this

national standard;

- To be consistent with other parts, add "NOTE. See GB/T 33012.1-2016 for a

detailed explanation of FPSC." in Annex A.

This Part is proposed by Ministry of Industry and Information Technology of the

People's Republic of China.

This Part is under the jurisdiction of National Technical Committee on Automobiles of

Standardization Administration of China (SAC/TC 114).

Road vehicles - Vehicle test methods for electrical

disturbances from narrowband radiated electromagnetic

energy - Part 2.Off-vehicle radiation sources

1 Scope

This Part of GB/T 33012 specifies the test conditions, test location, test equipment,

stimulation and monitoring of vehicle, test set-up and test procedure for vehicle test

methods for electrical disturbances from narrowband radiated electromagnetic energy

- off-vehicle radiation sources.

2 Normative references

The following referenced documents are indispensable for the application of this

document. For dated references, only the dated edition cited applies. For undated

references, the latest edition of the referenced document (including all amendments)

applies.

GB/T 33012.1-2016 Road vehicles - Vehicle test methods for electrical disturbances

from narrowband radiated electromagnetic energy - Part 1.General (ISO 11451-1.

2005 + A1.2008, MOD)

3 Terms and definitions

For the purposes of this document, the terms and definitions given in GB/T 33012.1-

2016 apply.

4 Test conditions

The applicable frequency range of this test method is 0.01 MHz to 18 000 MHz. Testing

over the full frequency range could require different field-generating devices, but this

does not imply that testing of overlapping frequency ranges is required.

5 Test location

The test should be performed in an absorber-lined shielded enclosure (simulated open

field).

6 Test equipment

The field generating device may be an antenna or antennas, or a TLS, and whose

construction and orientation shall be such that the generated field can be polarized in

the mode specified in the test plan

7 Stimulation and monitoring of vehicle

The DUT shall be operated as required in the test plan by using actuators which have

a minimum effect on the electromagnetic characteristics of the DUT, e.g. plastic blocks

on the push-buttons, pneumatic actuators (with plastic tubes for gas supply).

8 Test set-up

No part of the radiating antenna shall be closer than 0.5 m to the outer body surface

of the vehicle.

No part of a TLS, with the exception of the ground plane, shall be closer than 0.5 m to

any part of the vehicle.

9 Test procedure

The test shall be carried out using the substitution method, which is based on the use

of forward power as the reference parameter used for field calibration and during

testing.

As required by the test plan, a test report shall be submitted detailing information

regarding the test equipment, test site, test set-up, systems tested, frequencies, power

levels, system interactions and any other information relevant to the test.
