NF ISO 9211-3, S10-005-3 (03/2024)

ISO 9211 (all parts) describes surface treatments of components and substrates, excluding ophthalmic optics (spectacles) by the application of optical treatments, and standardizes their specification. It defines the general characteristics and the methods of testing and measurement whenever necessary, but it is not intended to define the manufacturing method. This document specifies the general use and standard use categories for optical coatings and identifies the environmental tests necessary to demonstrate that the coatings meet the required specification. The mechanical and chemical properties of treated optical elements, and more generally their environmental sustainability, can be evaluated by various methods. Test methods are generally described in different parts of ISO 9022 and in ISO 9211-4. These test methods are chosen so as to give meaningful results representative of the actual exposure of optical elements in their operating environment, or in accordance with the minimum requirements described in ISO 9211-5 to ISO 9211-8, which are associated to the type of treatment.
