Analyzing Interlaboratory Data According to ASTM Standard E691


ASTM Standard Practice E691-92 deals with the design and the analysis of the data of an interlaboratory study of a test method. This paper explains the procedure of E691 and goes beyond it in a discussion of the linear model analysis of interlaboratory test data. The explanations are illustrated in terms of a real set of interlaboratory data.
