Scope

This Part of GB/T 24338 specifies the emission and immunity requirements and
performance criteria of signalling and telecommunications apparatus (hereafter
abbreviated as “apparatus”) in the railway environment.
This Part applies to the apparatus included in GB/T 24338.4 being installed in
the railway environment and working normally, and the telecommunications
signalling data line and power line connected to the apparatus under test.
The emission and immunity requirements of on-board signalling and
telecommunications apparatus are specified by GB/T 24338.4. The emission
and immunity requirements of signalling and telecommunications apparatus
installed in the substation and connected to the substation are specified by
GB/T 24338.6. The electromagnetic compatibility requirements of apparatus
within the scope of GB 17625.1 or GB/T 17625.2 are specified by GB 17625.1
or GB/T 17625.2.
If the emission of the apparatus meets the emission limits specified in GB
17799.4, as long as the emission of any DC power port is less than the specified
emission limits of AC power port, it also complies with the provisions of this Part.
The immunity requirements specified in this Part apply to.
- Key apparatus, such as interlock system and signalling control system;
- Apparatus in 3 m zone;
- Apparatus in 10 m zone with ports connected to apparatus in 3 m zone;
- Apparatus in 10 m zone with more than 30 m of cable connected.
Apparatus not covered above shall comply with the provisions of GB/T 17799.2.
The immunity level specified for the apparatus in this Part allows the apparatus
to operate properly in the railway environment in most cases. When the
apparatus is directly exposed to interference, or the cable connected to it
receives interference from the RF field of disturbance source or coupled
