This guide applies to unfused low-voltage ac power circuit breakers of the 635 V maximum voltage class with separately-mounted current-limiting fuses for use on ac circuits with available short-circuit currents of 200 000 A (rms symmetrical) or less. Low-voltage ac fused power circuit breakers and combinations of fuses and molded-case circuit breakers are not covered by this guide. In this guide, the term circuit breaker means unfused low-voltage ac power circuit breaker.

The scope of this standard is limited to commercially-produced, solid radioactive flood sources intended to aid in the determination of the system field uniformity of scintillation cameras used in nuclear medicine. This standard is intended to provide a set of minimum informational requirements for a Test and Measurement Report for flood sources used with scintillation cameras. It is not intended to specify the means by which such information is obtained, although it does place requirements and… read more limitations on the methodology. In addition, it is not intended to cover the use of the source in the determination of the operating characteristics or correction factors for a scintillation camera. read less
This standard specifies methods for assessing the radio-frequency (RF) wireless coexistence of equipment that incorporates RF communications. This standard specifies key performance indicators (KPIs) that can be used to assess the ability of the equipment under test (EUT) to coexist with other equipment in its intended operational environment.
