ISO 9211-3:1994, Optics and optical instruments -- Optical coatings -- Part 3: Environmental durability

Identifies surface treatments of components and substrates excluding ophthalmic optics (spectacles) by the application of optical coatings and gives a standard form for their specification. Defines the general characteristics and the test and measurement methods whenever necessary, but is not intended to define the process method. This part specifies categories of use for optical coatings and identifies corresponding environmental tests.
