BS EN ISO 6507-4:2005 gives tables of Vickers hardness for use in tests made on flat surfaces

Aerodynamic equivalent diameter is the diameter of a unit-density sphere having the same gravitational-settling velocity as the particle in question

Note: For unbonded tendons

"standard wall" and "thick wall" related to nominal internal diameter and with corresponding differences in requirements for breakdown voltage

Rolling bearings. Thermal speed rating. Calculation Ingestion-build-117251 BS EN ISO 6507-4:2005 gives1 Scope This document defines the thermal speed rating for oil bath lubricated rolling bearings and defines calculation principles for the determination of this parameter. The parameter determined in accordance with this document applies to rolling bearings of the given series and sizes of standard design or of a design that, from a frictional point of view, can be related to a standard design bearing. In most cases of standard assembly, the
