Scope

The emission requirements specified in this document apply to electrical and electronic equipment used in an industrial location (see 3.1.12) environment. This document does not apply to equipment specified within the scope of GB17799.3. The environments described in this document include both indoor and outdoor environments in industrial locations. The applicable frequency range of this document is 9kHz~400GHz. This document provides sufficient protection for radio reception in the selected frequency range. Unspecified frequency bands need not be measured. The requirements of this document are essential to provide an adequate level of protection for radio services. For the purpose of experimentation, this document does not contain all disturbance phenomena, but only considers the relevant disturbance phenomena of the equipment expected to work in the environment covered by this document. This document specifies test requirements for each type of port considered. If there is no relevant product or product class electromagnetic compatibility (EMC) emission standard, the general EMC emission standard of this document applies. Note 1: This document has no safety requirements. Note 2: In special cases, the limits specified in this document may not provide adequate protection, for example, the use of sensitive receiving equipment near the equipment. In these cases, additional corrective measures may be required. Note 3: This document does not consider the disturbance caused by equipment failure.
