发布日期:1988-07
标准范围
描述了使用最小二乘准则将二次、三次或更高次多项式表达式拟合到非线性校准数据集的程序,以及评估与产生的校准曲线相关的不确定度的程序。ISO 7066-1介绍了将直线拟合到流量测量校准数据的方法。
Describes the procedures for fitting a quadratic, cubic or higher degree polynomial expression to a non-linear set of calibration data, using the least-squares criterion, and of assessing the uncertainty associated with the resulting calibration curve. The method of fitting a straight line to flow measurement calibration data is dealt with in ISO 7066-1.
