22、nal standards bodies (ISO member bodies). The work of preparing International Standards 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. Internati
23、onal organizations, governmental and non-governmental, in liaison with ISO, also 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 rul
24、es given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. 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
25、least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16284 was prepared by Technical Committee ISO/TC
26、172, Optics and photonics, Subcommittee SC 7, Ophthalmic optics and instruments and by Technical Committee CEN/TC 170, Ophthalmic optics in collaboration. This second edition cancels and replaces the first edition (ISO 16284:2001), which has been technically revised. Since the publication of the fir
27、st edition in the year 2001, there have been a number of industry developments. Specifically, surface coater, front surface generator, lens measuring, inspection and lap feeder devices have all been developed. In order to communicate with these devices and to support new features on existing device
28、types, the maintenance committee has proposed a number of new labels and device types. This revised International Standard also proposes a way of dealing with file-based data transfers between devices and hosts. In addition, a number of clarifications has been made to further explain certain require
29、ments of the standard and deprecating several requirements because they have proved difficult to manage in practice. EN ISO 16284:2006vIntroduction This International Standard is the result of a desire shared by manufacturers of optical laboratory equipment and producers of software used in optical
30、laboratories to simplify the interconnection of their products. The International Standard defined herein provides: a method by which machines and computer systems conduct their exchanges of data; a method by which computer systems can initialize such parameters on machines as the manufacturers ther
31、eof allow; a method by which machines can initialize computer systems with information that the systems can use for various purposes; a method by which a machine can inform a computer system as to what information it wants to receive, thus allowing machines to define new interfaces dynamically; a st
32、andard set of records and device types that are used to communicate agreed upon sets of information. The last feature listed above requires that this International Standard be amended on a regular basis, as the need for new data elements is inevitable. EN ISO 16284:2006blank1Ophthalmic optics Inform
