It is the English
9、language version of EN ISO 8624:1996 Optics and optical instruments Ophthalmic optics Measuring system for spectacle frames, published by the European Committee for Standardization (CEN). It is identical with ISO 8624:1991, published by the International Organization for Standardization (ISO). This
10、edition of the standard supersedes BS 3199:1972 which is withdrawn. BS 3199 was first published in 1960 and was subsequently revised in 1972. This current revision differs from the previous editions in that the standard now specifies the measurements that are required to indicate the dimensions of s
11、pectacle frames. Moreover the measuring system is based on the “boxed system” which is now more commonly used for locating spectacle lenses within the frames; this system replaces the datum system used hitherto and which was applied in the previous edition of BS 3199. Some definitions are included i
12、n this edition of BS 3199 (see Table 1), but the majority of the definitions given in BS 3199:1972 have been reproduced with little amendment in BS 3521-2:1991. The 1991 edition of BS 3521-2 includes the definitions required if ordering specially made frames. It has been assumed in the drafting of t
13、his British Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. At the time of publication of this standard, other British Standards that relate to spectacles include the following: BS 2738, Spectacle lenses. BS 3062, Specification for ophtha
14、lmic lens materials. BS 3172, Specification for screw threads for spectacle frames. BS 3521, Terms relating to ophthalmic optics and spectacle frames. BS 6625, Spectacle frames. BS 6903, Specification for graduated dial scales for ophthalmic instruments. BS 7394, Complete spectacles. A British Stand
15、ard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover,
