GB/T 18268.21-2025 Electrical equipment for measurement,control and laboratory use—EMC requirements—Part 21:Particular requirements—Test configurations,operational conditions and performance criteria for sensitive test and measurement equipment for EMC unprotected applications
Abstract
In addition to the requirements of GB/T 18268.1—2025, this document specifies more detailed test configurations, operating conditions, and performance criteria for devices with experimental and measurement circuits [internal and/or external circuits of the equipment]. According to the manufacturer's specifications, these devices do not have electromagnetic compatibility protection for operational and/or functional reasons.
Manufacturers need to specify the intended use environment of the equipment and select the appropriate test level from GB/T18268.1—2025.
Note: Such devices include, but are not limited to, oscilloscopes, logic analyzers, spectrum analyzers, network analyzers, analog instruments, digital multimeters, and circuit board testing systems.
