BS ISO 11726:2017描述了通过直接与相关国际标准方法进行比较，或通过与使用相关国际标准方法进行详尽分析的参考材料进行间接比较，验证煤炭和焦炭替代分析方法的程序。所使用的统计分析方法是参数化的，即只有当特征以近似线性尺度上的简单数字表示时，才可能使用这些方法。一些方法的结果，例如灰王焦炭类型，没有这样表示，只有当数据转换为参数比例时，才需要使用这里给出的方法。交叉引用:ISO 5725-6:1994ISO 3534-1:2006ISO 351购买本文件时可获得的所有现行修改件均包含在购买本文件中。

BS ISO 11726:2017 describes procedures for validating alternative methods of analysis for coal and coke either directly by comparison with the relevant International Standard method or indirectly by comparison with reference materials that have been exhaustively analysed using the relevant International Standard method.The statistical analysis methods used are parametric, i.e. their use is possible only when the characteristic is expressed as a simple number on an approximately linear scale. The results from some methods, for example the Gray-King coke type, are not so expressed and the methods given here need to be used only if the data are converted to a parametric scale.Cross References:ISO 5725-6:1994ISO 3534-1:2006ISO 351All current amendments available at time of purchase are included with the purchase of this document.
