Renewable energy and hybrid systems for rural electrification - Part 9-8: Integrated systems - Requi...
IEC 62257-9-8:2020 provides baseline requirements for quality, durability and truth in advertising to protect consumers of off-grid renewable energy products. Evaluation of these requirements is based on tests described in IEC TS 62257-9-5. This document can be used alone or in conjunction with other international standards that address the safety and durability of components of off-grid…
Plain bearings — Hydrodynamic plain journal bearings under steady-state conditions — Part 4: Permiss...
This document establishes the permissible operational parameters in terms of guide values for the calculation of selected multi-lobed and tilting-pad journal bearings.
In order to attain a sufficient operational safety of multi-lobed and tilting-pad journal bearings by the calculation according to ISO/TS 31657-1, it is necessary for the operational characteristic value hmin to be significantly…
Plain bearings — Hydrodynamic plain journal bearings under steady-state conditions — Part 2: Functio...
This document specifies the characteristic values for selected two-, three- and four-lobe bearings.
The functions plotted and listed in table form below are required for the operationally safe design of hydrodynamic multi-lobed journal bearings according to ISO/TS 31657-1. They are based on the presumptions and boundary conditions indicated there and only apply to stationary operating states. The…
