DIN ISO 9211-3
Optics and photonics - Optical coatings - Part 3: Environmental durability (ISO 9211-3:2008)
Optik und Photonik - Optische Schichten - Teil 3: Umweltbeständigkeit (ISO 9211-3:2008)
Overview
The DIN ISO 9211 standard series describes surface treatments of components and substrates excluding 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 does not cover the process methods, however. This standard DIN ISO 9211-3 specifies categories of use for optical coatings and identifies which environmental tests are necessary to prove that the coatings meet the required specification. The International Standard has been prepared by ISO/TC 172/SC 3 "Optical materials and components", the secretariat of which is held by JISC. On the national level, the Committee responsible for the standard is Working Committee NA 027-01-03 AA "Dünne Schichten für die Optik" ("Optical coatings") at NAFuO.
