Desktop and notebook computers - Measurement of energy consumption
IEC 62623:2012 covers personal computing products. It applies to desktop and notebook computers as defined in 4.1 that are marketed as final products and that are hereafter referred to as the equipment under test (EUT) or product. This standard specifies: - a test procedure to enable the measurement of the power and/or energy consumption in each of the EUT's power modes; - formulas for calculating the typical energy consumption (TEC) for a given period (normally annual); - a majority profile that should be used with this standard which enables conversion of average power into energy within the TEC formulas; - a system of categorisation enabling like for like comparisons of energy consumption between EUTs and a pre-defined format for the presentation of results. This standard does not set any pass/fail criteria for the EUTs. Users of the test results should define such criteria. Keywords: Power consumption, Desktop computer, Notebook computer

Computer information system (site) lightning protection safety inspection technical specification
This Standard describes a simple example of verification and validation (V&V) to illustrate some of the key concepts and procedures presented in V&V 10. The example is an elastic, tapered, cantilever, box beam under nonuniform static loading. The validation problem entails a uniform loading over half the length of the beam. The response of interest is the tip deflection. The validation test plan and the metrics and accuracy requirements for comparing the calculated responses with measurements are specified in theV&VPlan, which is developed in the first phase of the V&V program. In setting validation requirements and establishing a budget for the V&V program, the V&V Plan considers the level of risk in using the model for its intended purpose. Successfully meeting the V&V requirements means that the computational model for the tapered beam has been validated for the intended use discussed in this document, viz., predicting the response of a tapered beam tested in the laboratory. The following two validation approaches were considered: (a) a case where uncertainty data were not available and obtained instead from subject matter experts. (b) a case where uncertainty data were available from repeat tests and calculations.
