ISO 9211-4:2006

ISO 9211-4:2006 describes surface treatments of components and substrates excluding ophthalmic optics (spectacles) by the application of optical coatings, and gives a standard form for their specification. It defines the general characteristics and the test and measurement methods whenever necessary, but is not intended to define the process method. ISO 9211-4:2006 describes specific test procedures for coating environmental durability tests that are identified in ISO 9211-3 but not described in other normative references.
