Petroleum and related products - Precision of measurement methods and results - Part 1: Determination of precision data in relation to methods of test

active, Most Current
Organization: CEN
Publication Date: 1 December 2017
Status: active
Page Count: 86
ICS Code (Petroleum products in general): 75.080
scope:

This document specifies the methodology for the design of an Interlaboratory Study (ILS) and calculation of precision estimates of a test method specified by the study. In particular, it defines the relevant statistical terms (Clause 3), the procedures to be adopted in the planning of ILS to determine the precision of a test method (Clause 4), and the method of calculating the precision from the results of such a study (Clauses 5 and 6).

The procedures in this document have been designed specifically for petroleum and petroleum related products, which are normally considered as homogeneous. However, the procedures described in this document can also be applied to other types of homogeneous products. Careful investigations are necessary before applying this document to products for which the assumption of homogeneity can be questioned.
