Measurement of fluid flow in closed conduits, Part 7.2: Assessment of uncertainty in the calibration and use of flow measurement devices - Non-linear calibration relationships
封闭管道中流体流量的测量 第7.2部分:流量测量装置校准和使用的不确定度评定.非线性校准关系
Deals with procedures for fitting a quadratic, cube or higher degree (integer powers) polynomial expressions to a non-linear (or linear) set of calibration data using the least-squares criterion and assessment of the uncertainty associated with the resulting calibration curve. Because it is generally not practical to carry out this assessment without using a computer with standard routines an alternative FORTRAN program listing is included as an Annex. It is identical with and has been reproduced from ISO 7066-2:1988.
