Book Description
This Standard specifies methods of calculating the basic dynamic load rating of rolling bearings within the size ranges shown in the relevant standards, manufactured from contemporary, commonly used, high quality hardened bearing steel, in accordance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces. This Standard also specifies methods of calculating the basic rating life, which is the life associated with 90 % reliability, with commonly used high quality material, good manufacturing quality and with conventional operating conditions. In addition, it specifies methods of calculating the modified rating life, in which various reliabilities, lubrication condition, contaminated lubricant and fatigue load of the bearing are taken into account. This Standard does not cover the influence of wear, corrosion and electrical erosion on bearing life. This Standard is not applicable to designs where the rolling elements operate directly on a shaft or housing surface, unless that surface is equivalent in all respects to the bearing ring (or washer) raceway it replaces. Double-row radial bearings and double-direction thrust bearings are, when referred to in this document, presumed to be symmetrical. Further limitations concerning particular types of bearings are included in the relevant clauses.

Book Description
This Part applies to transfer switching equipment (TSE) to be used in power systems with interruption of the supply to the load during transfer, the rated voltage of which does not exceed 1000V a.c. or 1500V d.c. It covers: ——Manually operated switching equipment (MTSE); ——Remotely operated transfer switching equipment(RTSE); ——Automatic transfer switching equipment (ATSE). It covers TSE provided with or without an enclosure. Devices necessary for the control (e.g. control switches, etc.) and the protection (e.g. circuit-breakers, etc.) of a TSE shall comply with the relevant national standards. TSE used only for emergency lighting may be subject to specific rules and/or legal requirements and are not, therefore, covered by this standard.
