ISO Standards on Optical Test Methods

Abstract

Standardization is aimed at an internationally uniform application of terms, formulas, symbols and nomenclature to avoid misunderstandings or even unfair competition. In addition, standardization of measuring equipment avoids undetected systematic errors of different magnitude which may affect the accuracy of the measurement results obtained. Finally, standardization of measurement parameters allows measurement results obtained with instruments made by different manufacturers to be more easily compared. Standardization of test methods thus is a prerequisite for a fair quality assessment of products, and apart from being of technical and scientific interest, it is also of great commercial importance.
