IEC 60605-6-2007 设备可靠性测试.第6部分:恒定失效率和恒定失效密度的有效性和评估试验
简介:This standard specifies procedures to verify the assumption of a constant failure rate orconstant failure intensity, as defined in IEC 60050(191), and to identify patterns in the failurerate or intensity. These procedures are applicable whenever it is necessary to verify suchassumptions. This may be due to a requirement or for the purpose of assessing any variationwith time of the failure rate or failure intensity.The objectives of the methods specified in this standard are as follows:– to test whether the times to failure of non-repaired items are exponentially distributed, i.e.the failure rate is constant;– to test whether the times between failures of repaired item(s) have any time trend, i.e. thefailure intensity does not exhibit an increasing or decreasing trend;– to construct graphs that allow the patterns in the failure rate or failure intensity to bedisplayed, with a view to verifying whether they can be assumed constant, to estimate theirvalues or to identify the nature of any departure from constancy.

These procedures are applicable whenever it is necessary to verify these assumptions. This may be due to a requirement or for the purpose of assessing the behaviour in time of the failure rate or the failure intensity.The tests specified in this International Standard are one of the following:- to test whether the times to failure of items are exponentially distributed, i.e. the failure rate is constant;- to test whether the times between failures of a single repaired item do not have any time trend, i.e. the failure intensity does not exhibit an increasing or decreasing trend.

ASTM D7759-2012 核表面水分和密度调校准设备调整标准指南
简介:Gauge calibration is performed for the following purposes: To formulate a mathematical equation, or density calibration equation, that relates the gauge density system response (the x201C;density countx201D;) to the soil-equivalent density of the standard on which this response is elicited. To formulate a mathematical equation, or water content calibration equation, that relates the gauge water content system response (the x201C;water content countx201D;) to the water mass per unit volume value of the standard on which this response is elicited. To ensure that the gauge has an in-place water mass per unit volume gauge precision level that is consistent with typical gauge response. Gauge verification is performed for the following purposes: To indicate to the party or agency performing the verification when the mathematical relationship between the in-place density reading indicated by the gauge and the corresponding gauge density test count needs to be adjusted so that the gauge calibration meets the required level of measurement uncertainty. To indicate to the party or agency performing the verification when the mathematical relationship between the water mass per unit volume indicated by the gauge and the corresponding gauge water content test count needs to be adjusted so that the gauge calibration meets the required level of measurement uncertainty. Gauge verification and calibration require specialized training and equipment. Gauge calibration and verification should only be conducted by those trained in the proper operation of the gauge, the calibration or verification standards, and any tables, charts, graphs, or computer programs required for the proper execution of these operations.1.1 This guide describes the process and objective of calibrating the density system of a nuclear surface moisture and density gauge, or formulating the mathematical relationship between the density system response (the x201C;density countx201D;) of a nuclear surface moisture and density gauge and the corresponding density value of the density standard upon which the density system response was observed. 1.2 This guide describes the process and objective of calibrating the water content system of a nuclear surface moisture and density gauge, or formulating the mathematical relationship between the water content system response (the x201C;water content countx201D;) of a nuclear surface moisture and density gauge and the corresponding water mass per unit volume value of the water content standard upon which the water content system response was observed. 1.3 This guide describes the process and objective of verifying the density system of a nuclear surface moisture and density gauge. 1.4 This guide describes the process and objective of verifying the water content system of a nuclear surface moisture and density gauge. 1.5 This guide describes two mathematical processes by which the gauge measurement precision may be computed or measured. 1.6 This guide offers guidance for developing and reporting estimates of uncertainties in measurements made with gauges that have undergone calibration or verification. 1.7 All observed and calculated values shall confirm to the guide for significant digits and rounding established in Practice D6026. 1.8 This guide does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this guide to estab......
