PD IEC/TR 63133 introduces the method to estimate the degree of ageing of a semiconductor device

BS EN 62298-1 specifies an encoding and transmission scheme that is designed to be as efficient and robust as possible consistent with conveying potentially large data files via a unidirectional channel or bidirectional channel with a low or high data rate

Railway applications. Track. Track geometry quality - Measuring systems. Track construction and maintenance machines Ingestion-build-93833 BS 2059 includes details on1 Scope This European Standard specifies the minimum requirements that shall be met by measuring systems fitted on track construction and maintenance machines to give an evaluation of track geometry quality when measuring one or more of the parameters described in EN 138481. It does not seek to prescribe which parameters are to be measured, since these depend upon the measuring capabilities of the machine and the purpose for which the machine or its
