8、ization) is a worldwide federation of national 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
9、be represented on that committee. International 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 Stand
10、ards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 ca
11、sting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14975 was prepared by Technical Committee ISO/
12、TC 201, Surface chemical analysis, Subcommittee SC 3, Data management and treatment. Annexes A and B of this International Standard are for information only.ISO 14975:2000(E) ISO 2000 All rights reserved v Introduction ISO 14976 provides a digital data transfer format for communicating surface chemi
13、cal analysis data. Since the importance of databases is increasing in many scientific fields, storage and manipulation of spectral data in databases have become necessary. The structure of ISO 14976 is suitable for communication, but database manipulation is quite different from data communication.
14、Information additional to that contained in ISO 14976 is necessary to handle the data in the databases, so this International Standard proposes three formats which define information packages for (1) specimen information, (2) calibration information and (3) data processing information, which are imp
15、ortant to manipulate spectral data in databases. The future compatibility of the format is essential. This format is designed to work with ISO 14976 so that software designed to read the latter will still function correctly with these information packages added. This International Standard, therefor
16、e, is supplementary to and compatible with ISO 14976. The motivation behind the choices made in defining the textual form of the data files described in this International Standard are important. To make it easy for programmers to implement the format reliably in new software, aspects of the Microso
17、ft Windows“ .INI” file structure are followed. Most modern computers have facilities to read and write this format from a wide range of computer languages via the Windows Application Programming Interface.INTERNATIONAL STANDARD ISO 14975:2000(E) ISO 2000 All rights reserved 1 Surface chemical analys
18、is Information formats 1 Scope This International Standard specifies a format to supplement ISO 14976 to transfer data for the creation, expansion and revision of a surface chemical analysis spectral database. The format is applied to Auger electron spectroscopy (AES) and X-ray photoelectron spectro
19、scopy (XPS) spectral data. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.
20、However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO an
21、d IEC maintain registers of currently valid International Standards. ISO 14976, Surface chemical analysis Data transfer format. 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 spectral database set of retrievable spectral data 3

24、 DTF or attached to the DTF as packages. As a result, the existing DTF could be used, without alteration, as a carrier for the information packages; these packages occupy the experiment-comment line or the block-comment lines in the DTF, or build blocks outside the DTF. With this structure, the read
25、ing program, which utilizes information packages, can look for the format identifiers in either the experiment-comment lines, where they apply to all blocks, or in the block-comment lines, where they apply to just one block, or outside the DTF. Existing reading programs would interpret these package
26、s as comments intended for human readers and ignore them. In this International Standard, the information packages for “specimen information format”, “calibration information format”, and “data processing format” are described. It is a modular structure so that compatibility with software previously
27、 written is always maintained. 5.2 Additional rules and definitions text line: up to 80 characters, followed by carriage return character: one alternative from the following set comprising the character SPACE and the 7-bit ASCII character set: | ! | “ | # | $ | % | | | ? | | A | B | C | D | E | F |
