GB 17799.4-2022 Electromagnetic compatibility (EMC) — Generic standards — Part 4: Emission for industrial environments
1 Scope
This document specifies emission requirements applies to electrical and electronic equipment intended for use within the environment existing at industrial (see 3.1.1 2) locations.
This document does not apply to equipment that fall within the scope of GB 17799.3.
The environments encompassed by this document cover both indoor and outdoor locations.
Emission requirements in the frequency range 9 kHz to 400 GHz are covered in this document and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. No measurement needs to be performed at frequencies where no requirement is specified. These requirements are considered essential to provide an adequate level of protection to radio services.
Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the environments included within this document.
Test requirements are specified in this document for each port considered.
This generic EMC emission standard is to be used where no applicable product or product-family EMC emission standard is available.
Note 1: Safety considerations are not covered by this document.
Note 2: In special cases, situations will arise where the levels specified in this document will not offer adequate protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances, special mitigation measures may have to be employed.
Note 3: Disturbances generated in fault conditions of equipment are not covered by this document.
