2、:1994(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for
3、which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on al
4、l matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0
5、 921 l-3 was prepared by Technical Committee lSO/TC 172, Optics and optical instruments, Subcommittee SC 3, Optical materials and components.

The requirements for each cate- gory are qualitatively outlined below, and specified in table 1
15、. Category A This refers to applications which would normally only apply to components mounted internally within sealed units. The use in this category is in a protected and controlled environment and handling should only take place with extreme care. Category B This refers to applications where com
16、ponents will be exposed only to a controlled environment. Such applications can include mild abrasion as occurs with carefully controlled cleaning. Category C This refers to applications where components will be exposed to normal outdoor ambient conditions and uncontrolled cleaning without severe ab
17、rasion and 1) To be published. 1 IS0 9211=3:1994(E) 0 IS0 scratching. Typical applications would apply to external surface antireflection coatings on cameras and bin- oculars. Category D This refers to applications where components will be exposed to severe outdoor ambient conditions and uncontrolle
18、d cleaning with severe abrasion and scratching. Category 0 This refers (optional). to applications adapted to special conditons The requirements for coatings as listed in table 1 are typically not accumulative and can be tested individually. 3.2 Modification of categories Some intended applications
19、of components 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 of which most requirements are satisfied. The exceptional requirements can then be specified from other categories. EXAMPLE “Category C; Abrasion, Hum
20、idity: Category B” 3.3 Operating and storage conditions The temperature specifications in table 1 are meant as storage conditions. For some types of coatings, e.g. bandpass filters and accurate edge filters, it may be necessary that spectral tolerances have to be main- tained within a certain temper
21、ature range. This should be specified separately, according to the requirements of the application. 3.4 influence of the substrate It should be kept in mind, that, in fact, it is not the coating but the entire coating-substrate combination which determines the category of use. For instance, coatings
