Optics and photonics - Optical coatings - Part 4: Specific test methods (ISO 9211-4:2012)
Optik und Photonik - Optische Schichten - Teil 4: Spezifische Prüfmethoden (ISO 9211-4:2012)
Overview
The standard DIN ISO 9211-4 is part of a series of standards specifying surface treatments of components and substrates (excluding ophthalmic optics/spectacles), by the application of optical coatings. This part of ISO 9211 describes specific test procedures for coating environmental durability tests that are identified in ISO 9211-3 but not described in other normative references. They are typically performed in sequence with other test methods for testing the environmental durability of coatings, as described in ISO 9211-3:2008, Annex A. The responsible body involved in the preparation of this standard was NA 027-01-03 AA "Dünne Schichten für die Optik" ("Optical coatings") at DIN.
