and measurement techniques -- Radiated, radio-frequency, electromagnetic field

immunity test". Compared with GB/T 17626.3-2016, in addition to the structural and

editorial changes, the main technical changes in this document are as follows.

- Add the content of immunity test of RF sources adjacent to EUT (see Chapter 1 of

this Edition);

- Delete the definitions of Ec, Et, independent window method, induction field, Pc

and scanning (see 3.10, 3.11, 3.14, 3.15, 3.20, 3.24 of Edition 2016);

- Add the definitions of common mode absorption device, intermodulation,

modulation factor, and reference ground plane (see 3.1.8, 3.1.17, 3.1.20, 3.1.24

of this Edition);

- Add abbreviated terms (see 3.2 of this Edition);

- Delete the test levels for digital wireless phones and other radio frequency

transmitting devices (see 5.2 of Edition 2016);

- Delete the 0.8m requirement for insulating tables and UFAs in the facility layout

(see Figure 2 of Edition 2016);

- Delete the requirement for the lower edge of 0.8 m in the picture in the UFA feature

(see Figure 3 of Edition 2016);

- Delete the description that the product is not too big, heavy and safe and can be

placed on a 0.8m high insulation table for testing (see 7.2 of Edition 2016);

- Add the requirement to use common mode absorbing devices to decouple cables

(see 7.4 of this Edition);

- Delete the upper limit requirement of the general test level frequency range (see

2006 The third revision was in 2016.

3 Terms, definitions and abbreviated terms

For the purposes of this document, the following terms and definitions apply.

4 General

Electronic equipment can, in some manner, be affected by electromagnetic radiation.

This radiation is frequently generated by various sources, such as small hand-held radio

transceivers, fixed-station radio and television transmitters, vehicle radio transmitters

and industrial electromagnetic sources. Many of these services use modulation

techniques with a nonconstant envelope.

8 Test procedure

9 Evaluation of test results

The test results shall be classified in terms of the loss of function or degradation of

performance of the equipment under test, relative to a performance level defined by its

manufacturer or the requestor of the test or agreed between the manufacturer and the

purchaser of the product.
