ISO has just released ISO 9211-4, 3rd Edition, “Optics and photonics — Optical coatings — Part 4: Specific test methods,” and it’s available now from Document Center Inc. The standard 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 environmental durability tests, as shown in ISO 9211-3:2008, Annex A.
The 20-page ISO 9211-4:2012 cancels and replaces the second edition (ISO 9211-4:2006), which has been technically revised.
The ISO 9211 series describe 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 wherever necessary, but it is not intended to define the process method.
The other standards in the series are:
- ISO 9211-1:2010, Optics and photonics — Optical coatings — Part 1: Definitions
- ISO 9211-2:2010, Optics and photonics — Optical coatings — Part 2: Optical properties
- ISO 9211-3:2008, Optics and photonics — Optical coatings — Part 3: Environmental durability
Another ISO standard of interest on this topic is ISO 14997:2011, “Optics and photonics — Test methods for surface imperfections of optical elements.”
