<p>The purpose of ISO/TR 24430:2003 is:</p>
<ul><li>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;</li><li>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;</li><li>to outline the general principles under which interlaboratory trials should be conducted.</li></ul>
<p>It 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.</p>
<p>It is 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.</p>
