Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 2: Absorber-lined shielded enclosure
1 Scope
This part of GB/T 33014 specifies component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - absorber-lined shielded enclosure.
This part is applicable to electrical/electronic components for Categories M, N, O and L vehicles, regardless of vehicle propulsion system (e.g. spark-ignition engine, diesel engine and electric motor).

GB/T 33014.1-2016 Road vehicles - Component test methods for electrical/electronic disturbances from narrowband radiated electromagnetic energy - Part 1: General (ISO 11452-1: 2005, MOD)
3 Terms and definitions
For the purposes of this document, the terms and definitions given 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 users shall specify the test severity level(s) over the frequency range. Suggested test severity levels are included in Annex C.
The device under test (DUT), together with the wiring harness (prototype or standard test harness), is subjected to an electromagnetic disturbance generated inside an absorber-lined shielded enclosure, with peripheral devices either inside or outside the enclosure.
Standard test conditions shall be according to GB/T 33014.1-2016 for the following:
——test temperature;
——test voltage;
——modulation;
——dwell time;
——frequency step sizes;
——definition of test severity levels;
——test signal quality.
5 Test location
The tests shall be performed in an absorber-lined shielded enclosure (simulated open field).
Basically, an absorber-lined shielded enclosure consists of a shielded room with absorbing material on its internal reflective surfaces, optionally excluding the floor. The design objective is to attenuate the reflected energy in the test area by at least 10 dB compared to the direct energy.
