BS IEC 60462:2010 Nuclear instrumentation. Photomultiplier tubes for scintillation counting. Test procedures
BS IEC 60462 is an International Standard which establishes test procedures for photomultiplier tubes (PMT) for scintillation and Cherenkov detectors.
BS IEC 60462 is applicable to photomultiplier tubes for scintillation and Cherenkov detectors.
Photomultiplier tubes are extensively used in scintillation and Cherenkov counting, both in the detection and analysis of ionizing radiation and for other applications. For such uses, various characteristics are of particular importance and require additional tests to those conducted to measure the general characteristics of PMT. This has made desirable the establishment of standard test procedures so that measurements of these specific characteristics may have the same significance to all manufacturers and users.
The tests described in BS IEC 60462 for PMT to be used in scintillation detectors are supplementary to those tests described in IEC 60306-4, which covers the basic characteristics commonly requiring specification for photomultiplier tubes.
This recommendation is not intended to imply that all tests and procedures described herein are mandatory for every application, but only that those tests carried out on PMT for scintillation and Cherenkov detectors should be performed in accordance with the procedures given in this standard.
