Over deze norm
Applies to instruments used in general, regional and local prospecting and for subsurface and deep survey, excluding radiometric bore hole logging probes. These instruments usually comprise a detecting device with one or more Geiger-Mueller counter tubes, a counting rate meter, a power supply, a listening device. A radioactive source for checking is usual. Object of the recommendation is to state requirements for instruments and to list the information to be provided in the instruction manual by the manufacturer. Gives in detail: accuracy requirements, intrinsic requirements, power supply requirements, requirements for resistance to environmental conditions, safety requirements and, as the specification to be given in the manual, general characteristics, power supply characteristics, performance characteristics, storage and transportconditions, safety characteristics.
