Optics and photonics. Optical coatings - Specific test methods not-eligible BS EN IEC 61238-1-1 is1 Scope ISO 9211 describes 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. This part of ISO 9211 describes specific test procedures for coating environmental durability
