This International Standard covers the calculation of precision estimates and their application to specifications.In particular, it contains definitions of relevant statistical terms (Clause 3), the procedures to be adopted in theplanning of an inter-laboratory test programme to determine the precision of a test method (Clause 4), themethod of calculating the precision from the results of such a programme (Clauses 5 and 6), and theprocedure to be followed in the interpretation of laboratory results in relation both to precision of the testmethods and to the limits laid down in specifications (Clauses 7 to 10).The procedures in this International Standard have been designed specifically for petroleum and petroleumrelatedproducts, which are normally homogeneous. However, the procedures described in this InternationalStandard can also be applied to other types of homogeneous products. Careful investigations are necessarybefore applying this International Standard to products for which the assumption of homogeneity can bequestioned.
