This document specifies a calculation procedure for the maximum bearing temperature and effective dynamic viscosity in the lubricant film of oil-lubricated and statically loaded hydrodynamic plain journal bearings with a circular cylindrical shape, angular span Ω of 360° and width ratio B* of 0,5 to 1,5 under fluid lubrication regime. The bearing characteristics are obtained by design charts from…

Passive RF and microwave devices, intermodulation level measurement - Part 7: Field measurements of ...
IEC 62037-7:2022 defines test methods for reverse measurement of passive intermodulation (PIM) in systems of RF components deployed in the field. Field PIM measurements can be conducted on RF systems terminated into low PIM loads or on antenna feed systems that broadcast the test signals into the environment.
