英文名称：Paints and varnishes - Guidelines for the determination of the precision of a test method by interlaboratory trials
发布日期：2003-10
起草单位：ISO/TC 35
标准简介：The purpose of these guidelines is:
—  to give recommendations on how to introduce precision statements into an International Standard which specifies a test method for paints, varnishes, related materials and coatings derived from them;
—  to outline the general principles to be applied when assessing precision in order to establish the procedures which will enable a quantitative estimate to be made;
—  to outline the general principles under which interlaboratory trials should be conducted.
These guidelines may be applied to paints, varnishes and related products, to their raw materials in solid, liquid or powder form and to coatings derived from them.
The guidelines are concerned only with test methods which operate on a continuous scale to yield a single numerical figure as the test result. However, this single figure may be the outcome of a calculation from a set of measurements. The distribution of test results is required to be unimodal and is assumed to be normal. With non-Gaussian distributions other evaluation procedures will be necessary. It does not cover methods which yield discrete values such as go no-go tests or where a ranking scheme is in operation.
