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 the planning of an interlaboratory test programme to determine the precision of a test method (Clause 4), the method of calculating the precision from the results of such a programme (Clause 5 and Clause 6), and the procedure to be followed in the interpretation of laboratory results in relation both to precision of the test methods and to the limits laid down in specifications (Clause 7 to Clause 10). It is emphasized that the procedures in this International Standard are designed to cover methods of test for petroleum and petroleum-related products only. The latter are, in general, homogeneous products with which serious sampling problems do not normally arise. Before widening the application of this International Standard to other products, for example to heterogeneous solids, careful investigations should be taken into consideration.
