13、s 1 Scope ISO 9211 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 necess
14、ary. It is not intended to define the process method. This part of ISO 9211 specifies categories of use for optical coatings and identifies which environmental tests are necessary to prove that the coatings meet the required specification. Definitions and the extent of testing are given in ISO 9022-

19、 of use are defined. Each category requires either different environmental tests and/or different severity of testing. These categories are listed below in order of severity of requirement. Part 3: Environmental durability 5 DIN ISO 9211-3:2010-12 Category A This category refers to components in app
20、lications which would normally only apply when they are to be mounted internally within sealed units. In this category, handling is in a protected and controlled environment and should only take place with extreme care. Physical contact with the optically coated surface is discouraged. Category B Th
21、is category refers to applications where components will be exposed only to a controlled environment. Such applications may involve mild abrasion such as occurs with carefully controlled cleaning. Category C This category refers to applications where components will be exposed to normal outdoor ambi
22、ent conditions and cleaning but without severe abrasion and scratching. Category D This category refers to applications where components will be exposed to severe outdoor ambient conditions and uncontrolled cleaning with the risk of severe abrasion and scratching. Category O This category refers to
23、applications which require special, non standard, specifications. Since the specification of the components in such cases will not exactly fit into one of the categories A to D, the recommended way to specify in such a case is to indicate first the category in which most requirements are satisfied.
24、The exceptional requirements can then be specified from other categories or by indicating the test degree of severity. EXAMPLE “Category C; Abrasion, Humidity: Category B; Adhesion: 03”. 3.2 Operating and storage conditions The temperature specifications listed in Table 1 are meant as storage condit
25、ions. For some types of coating, e.g. bandpass filters and accurate edge filters, it may be necessary that spectral tolerances shall be maintained within a certain temperature range. This should be specified separately, according to the requirements of the application. 3.3 Influence of the substrate
26、 It should be kept in mind that it is not the coating but the entire coating-substrate combination which determines the category of use. For instance, coatings on glass, normally satisfying category C, might not do so when applied to sensitive or unstable substrates. This is likely to become apparen
27、t with the rain, solubility, humidity, heat, and salt spray tests, for example. 3.4 Cemented coatings This part of ISO 9211 does not apply to cemented coatings. The environmental stability of such a substrate-coating-cement-substrate combination depends too much on properties of the cement, as well
28、as the (relative) properties, e.g. thermal expansion, of the two substrate components involved. 6 DIN ISO 9211-3:2010-12 4 Specifications The mechanical and chemical properties of coated optical elements, and more generally their environmental durability, can be assessed by a variety of methods. Tes
29、t methods selected to give meaningful results representative of actual exposure of optical elements in their operating environment are listed in Table 1. The practical severity of any test listed may be limited by the substrate. The requirements for coatings as listed in Table 1 are typically not ac
30、cumulative and can be tested individually. The tests in Table 1 are subdivided into degrees of severity, where appropriate. The severity of the test requirement increases with the number. The description is condensed information about the test method only. The full test procedure shall be taken from
31、 appropriate International Standards, referenced in Table 1, or can be specified by mutual agreement between customer and manufacturer. An individual test performed on a one-test-on-one-sample basis can give information about that single property of an optical coating reflected by that test and can
32、be particularly useful for the manufacturer. In reality, optical coatings will face a variety and range of severity of environmental exposures, which can be simulated by certain test sequences. Inevitably, such test sequences represent accumulative requirements. Requirements without any listed categ
33、ories in Table 1 are to be considered for optional use in category O, and are subject to agreement between customer and manufacturer.
