Analysis of steels and irons. Internal laboratory procedure for checking the accuracy of an analytical method by using Certified Reference Materials1 Scope The present statistical procedure describes how to check results for absence of bias by comparison of these analytical results with those obtained during the certification of CRMs. If the resulting data confirm the absence of bias, the method may be considered accurate when applied to all steels and irons whose composition ranges are adequately covered or bounded by the CRMs used. The resulting data give also an estimate of the repeatability
