This Part is Part 10 of GB/T 33014.

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

This Part uses the redraft law to modify and adopt ISO 11452-10.2009 "Road

vehicles - Component test methods for electrical disturbances from narrowband

radiated electromagnetic energy - Part 10.Immunity to conducted disturbances

in the extended audio frequency range".

The technical differences between this Part and ISO 11452-10.2009 and their

reasons are as follows.

- As for the normative references, this Part has made adjustments with

technical differences, to adapt to the technical conditions of China. The

adjustments are mainly reflected in Clause 2 "Normative references". The

specific adjustments are as follows.

 Replace ISO 11452-1 with GB/T 33014.1, which modifies and adopts

the international standard.

- Modify the notes in Table A.1.

- ADD annotations for category 1, category 2, and category 3 in Annex A.

This Part has made the following editorial changes.

- In order to be consistent with China's technical standard system, change

the standard name to "Road vehicles - Component test methods for

electrical/electronic disturbances from narrowband radiated

electromagnetic energy - Part 10.Immunity to conducted disturbances in

the extended audio frequency range";

- In accordance with the requirements of GB/T 1.1-2009, standardize the

writing of Clause 1;

- Simplify the title of Figure 1.

This Part was proposed by Ministry of Industry and Information Technology of

the PRC.

This Part shall be under the jurisdiction of National Technical Committee of Auto

Standardization (SAC/TC 114).

Road vehicles - Component test methods for

electrical/electronic disturbances from narrowband

radiated electromagnetic energy - Part 10.Immunity to

conducted disturbances in the extended audio

frequency range

1 Scope

This Part of GB/T 33014 specifies component test methods for

electrical/electronic (ESA) disturbances from continuous narrowband radiated

electromagnetic energy - immunity to conducted disturbances in the extended

audio frequency range.

2 Normative references

The following documents are indispensable for the application of this document.

For the dated references, only the editions with the dates indicated are

applicable to this document. For the undated references, the latest edition

(including all the amendments) are applicable to this document.

GB/T 33014.1 Road vehicles - Component test methods for

electrical/electronic disturbances from narrowband radiated electromagnetic

energy - Part 1.General (GB/T 33014.1-2016, ISO 11452-1.2005, MOD)

3 Terms and definitions

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

4 Test conditions

The applicable frequency range of immunity to conducted disturbances in the

extended audio frequency range is 15 Hz~250 kHz. The user shall specify the

test severity level or levels over the frequency bands (see Annex A).

5 Test location

This test does not require special grounding or shielding in the laboratory.

6 Test apparatus

A 100 µF capacitor may be used (for lines other than power lines) to shunt

the source end of the isolation transformer to ground if difficulty is encountered

in obtaining sufficient test voltage. Verification shall be made that desired

signals are not excessively disturbed by the 100 µF capacitor.

7 Test set-up

The test set-up is shown in Figure 1.A d.c. power amplifier that satisfies the

source impedance requirement of this Part and can supply the power required

by the DUT may be substituted for the power amplifier and isolation transformer

for power supply lead testing.

8 Test method

During the test, filters incorporated into DUTs may experience excessive and

potentially damaging current flow. To prevent this type of over stress in the DUT,

a current probe is included in the test set-up.

The system power supply voltage shall be set as specified in the test plan and

shall be measured at the DUT to account for voltage drop in the isolation

transformer secondary winding.

Annex A

(Informative)

Function performance status classification (FPSC)

This annex gives examples of test severity levels. For details of FPSC, see

GB/T 33014.1.

Annex B

(Informative)

Verification for source impedance

The following procedure can be used to verify the signal source impedance at

the isolation transformer secondary terminals.
