IEC/TC 45 - IEC_TC_45

IEC 62598:2011 applies to the manufacture and installation of electrical measuring systems and instruments utilizing radioactive sources (radiometric gauges, hereinafter called gauges). It also applies to source housings intended for use in the aforementioned measuring systems. This standard applies to equipment, which is not related to power production or to the fuel cycle. It specifies constructional requirements for the design of instruments utilizing radioactive sources in regard of radiation protection. This standards cancels and replaces IEC 60405.

Specifies requirements for hand-held photon spectrometers, in particular for the detectors, the electronic multi-channel analyzers, the identification software, the radionuclide libraries, and the instrument display. Also specifies general characteristics, general test procedures, radiation characteristics, as well as electrical, mechanical, safety, and environmental characteristics.

Specifies constructional requirements for the design of instruments and the radiation protection to be provided in the case of radiometric gauges. Special attention is drawn to the stability of the source housing in the event of fire.

Defines the terms specific to the CAMAC modular instrumentation and digital interface system which forms the subject of several IEC standards. It includes also other terms whose use is well established and those of corresponding characteristics of the NIM system of instrumentation.

Applicable to equipment used for prospecting radioactive ores or minerals responding to radioactive excitation, and for underground studies.

Dimensions of the standard plug-in unit and rack-mounting unit; connector dimensions and pin arrangements.

Defines a modular instrumentation system capable of linking transducers and other devices with digital controllers or computers. It consists of mechanical standards and signal standards sufficient to ensure compatibility between units from different sources of design and production. The CAMAC system is primarily designed for nuclear instrumentation but may be utilized also for other applications.

Standard interface between a number of 'CAMAC' measuring instruments, display units, control units, actuators, data processing equipment (computers) and communication equipment.

Characteristics of the 'parallel highway' for the CAMAC instrumentation and interface system described in HD 357.This highway provides for the high-speed transfer of data between CAMAC crates and computers or other controllers and for the interconnection of CAMAC crates in multicrate systems. Signal, timing and logical organization. Appendix: specifications of a standard crate controller.

Gives the standard values for the diameters, heights and wall thickness of planchets made in well flat and dish-type configurations.

Defines a method for incorporating more than one source of control into a CAMAC crate through auxiliary controllers located in normal stations in the crate. An auxiliary controller bus (ACB) and priority arbitration protocol are fully defined.

Presents a set of software subroutines to provide a general capability for communications with CAMAC systems as defined in EN 60516. The subroutines are suitable for use with Fortran although they are not restricted to that language.

Recommendations are presented for uniform practice with regard to block transfers in CAMAC modular instrumentation and digital interface systems of IEC 60516
