NF ISO 9211-1

The ISO 9211 series 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, but is not intended to define the process method. ISO 9211‑1:2010 defines terms relevant to optical coatings. These terms are grouped in four classes: basic definitions, definition of coatings by function, definitions of common coating imperfections and other definitions.
