Alpha, beta and alpha-beta contamination meters and monitors
Applies to assemblies designed to measure or detect the contamination of surfaces by alpha and/or beta radiation emitters. Lays down standard requirements: gives examples of acceptable methods; specifies general characteristics, general test conditions, radiation characteristics, electrical safety and environmental characteristics, and also the identification certificate.
Applies to traditional signal generators using tunable oscillators, to synchronizers for use with these, and to synthesizers and sweep generators. Does not apply to pulse generators.
Establishes the essential definitions; states the requirements intended for evaluating the electrical properties of signal generators; establishes a selection of standard performance characteristics from which the…
Dimensions of low-voltage switchgear and controlgear. Standardized mounting on rails for mechanical ...
Specifies dimensional and functional requirements for the compatible mounting of varied electrical devices on some types of rails in switchgear and controlgear assemblies. An appendix gives the standardized dimensions of steel mounting rails with Top Hat, C and G sections.
A second appendix provides an application guide for the use of rails.
