ISO 9211-3:2008

ISO 9211 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. It defines the general characteristics and the test and measurement methods whenever necessary. It is not intended to define the process method.
ISO 9211-3:2008 specifies categories of use for optical coatings and identifies which environmental tests are necessary to prove that the coatings meet the required specification.
