The work of preparing International St
9、andards is normally carried out through ISO technical committees. Each member body interested in a subject for 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
10、 take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopte
11、d 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. Attention is drawn to the possibility that some of the elements of this International Standard may be the sub

International Standard ISO 4168 was prepared by Technical Committee ISO/TC 114, Horology, Subcommittee SC 5, Luminescence. This second edition cancels and replaces the first edition (ISO 4168:1979
13、), which has been technically revised. BSISO4168:2002 1 Timekeeping instruments Conditions for carrying out checks on radioluminescent deposits 1 Scope This International Standard specifies the conditions in which checks on radioluminescent deposits for timekeeping instruments are to be carried out.
14、 It supplements ISO3157, in particular clause4 of that document, “Specifications and test methods for radioluminescent deposits”. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. F

20、of ISO 3157:1991 carried out in the following conditions. 4.2 Checking of the colours, the specific luminous intensity and resistance to ageing The colours, the specific luminous intensity and the resistance to ageing shall be checked on five standard deposits as defined in 4.1 c) of ISO 3157:1991,
21、for each production batch of radioluminescent substance and each time the nature of the binder is altered. These checks are the responsibility of the manufacturer of the radioluminescent substance. If a user applies the radioluminescent substance in conditions which differ from those defined by the
22、manufacturer of this substance (proportion and nature of the binder), the checks are the responsibility of such a user. 4.3 Checking of adhesion 4.3.1 The adhesion shall be checked as follows. 4.3.2 Check each production batch of radioluminescent substance and each production batch of binder, on fiv
23、e standard supports. These checks are the responsibility of the manufacturer of the radioluminescent substance. 4.3.3 Check each new support or new deposit which has not undergone testing by the user concerned, on at least five pieces. These checks are the responsibility of the user of the radiolumi
24、nescent substance. 4.3.4 Check each production batch of dials or hands or any part bearing a radioluminescent deposit, on a representative sample ensuring an acceptable quality level (AQL) of , in accordance with the standard inspection conditions specified in ISO 2859-1. These checks are the respon
25、sibility of the user of the radioluminescent substance. 4.4 Checking of the insolubility 4.4.1 The insolubility shall be checked as follows. 4.4.2 Check each production batch of radioluminescent substance and each production batch of binder, on the standard supports used for the checking of adhesion
26、 as defined in 4.3.2. These checks are the responsibility of the manufacturer of the radioluminescent substance. 4.4.3 Check on the new supports which were used for the checking of adhesion as defined in 4.3.3 when the new element concerns the support material or the surface treatment of the support
27、. These supports are the responsibility of the user of the radioluminescent substance. 1% BSISO4168:2002 3 5 Certificate of conformity 5.1 The manufacturer of the radioluminescent substance shall be required, at the request of the customer, to furnish a certificate with each delivery, indicating the
28、 production batch numbers, and stating the characteristics defined in 4.2 and 4.3 of ISO 3157:1991 for one or more types of binder and for one or more proportions of mixture, and conformity of the product with the specifications in 4.4, 4.5 and 4.6 of ISO 3157:1991. 5.2 The user of the radioluminesc
29、ent substance shall be required, at the request of the customer, to furnish a certificate with each delivery of hands or dials, guaranteeing, firstly, use of a radioluminescent substance complying with the specifications of ISO 3157 and, secondly, conformity with the specifications in 4.5 and 4.6 of
30、 ISO 3157:1991. 5.3 Both the manufacturer and the user of the radioluminescent substance shall be required, with due regard to national regulations applying to prescribed time limits, to file the reports on checks carried out on their production, as well as the duplicate copies of certificates accom
