12、odies (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. International organizati
13、ons, 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 rules given in the
14、 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 least 75 % of t
15、he 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 10617 was prepared by Technical Committee ISO/TC 38, Textiles, S

BS ISO 10617:2010ISO 10617:2010(E) ISO 2010 All rights reserved vIntroduction Spectrophotometers are now well established in the process and quality-control processes within the colour-using industries, as a tool for the measurement of colo
17、ur, and subsequent computation of colour difference, that is required for colour approval. Colorimetric data has increasingly become the choice as a “standard” for use in the specification of a colour, in preference to a physical sample, due to the accuracy, stability and mobility of data compared t
18、o physical samples. Textile production and sourcing, in particular, now have a truly global nature where manufacturing and retailing are literally continents apart. Product management and design have remained in the fashion centres (for example New York, Paris, London) whereas manufacturing goes whe
19、re the economics of production dictate. In addition, retail sales are global. An essential element for speed of response to market needs and for cost reduction of colour development and production is the effective communication of colorimetric data between different measurement systems. This enables
20、 the remote operation of processes such as colour approval, trim and range of colour coordination, etc. Currently, there are many suppliers of colour measuring instruments and software systems to support the computations associated with colour measurement. These include quality-control systems and r
21、ecipe prediction systems, as well as on screen colour systems. Colorimetric information generated by such systems is not readily consumed by other systems, as it is in a format known only to the system maker. Some systems can decode the data formats of other systems and allow transformation into a c
22、ompatible format. New and existing systems are continually being developed and new data formats introduced. These new data formats will not be readily understood or useable in other colour systems. In order that dissimilar systems can be used effectively in communicating colour, a common Data Standa
23、rd is required. This would allow the colorimetric data output from any system to be readily consumed by any other system, whether it is a colour system or business system. Data would be readily viewable by standard browser software and other simple data tools. XML is a meta-mark-up language develope
24、d for use with the Internet (WC3 endorsed standard) to allow the exchange of data between dissimilar systems. XML provides data about the data (meta-data), as well as the data itself, thereby allowing dissimilar systems to understand the contents of a standard XML document. It provides a standard fo
25、rmat for data in a document form. There are many utilities available to developers and users to enable the handling of data in this format and, since the underlying code is text-based, a simple editor can see the data included. The primary data communicated is usually the spectral data. Other data r
26、elating to illuminants and observers is a calculation based on the spectral data. The software receiving the spectral data must be more than capable of doing these well-defined calculations, according to internationally agreed ISO/CIE standards. Where only colorimetric data is being exchanged, there
27、 is provision for the observer and illuminant data to be included (see 6.2.5). Quality-control data, such as standard and batch association, profiling data, specific illuminant to be used, etc. is arbitrary and subject to agreement between the manufacturer and customer. This is outside the scope of
28、this International Standard. The header of the data being exchanged, as described in 6.1, includes a section entitled “Comments”, where quality-control data could possibly be communicated.

29、es Standard data format for colorimetric communication Textiles and related measurements 1 Scope This International Standard is primarily concerned with the exchange of the spectral data, which is the fundamental data behind the colour being communicated. This International Standard provides a stand
30、ard format for the interchange of data between a colorimetric measurement instrument and software used to make calculations based on those measured data. A key application is in the measurement and associated recipe formulation of dyes used in the textile industry. The application can, however, be t
31、o any industry where there is a need to communicate colorimetric data, e.g. pigment formulation in plastics and paints, colour management in the graphic arts and other colour reproduction industries. 2 Normative references The following referenced documents are indispensable for the application of t

It shows the order of the fields and how the format
34、 is laid out. None of the fields in the format are mandatory; the requisite field for the term can be left blank, in which case a default value is assumed. It should, however, be noted that the more information that is provided with the measurements, the greater the confidence that the recipient can
35、 have in the data. The format described is concerned solely with the data to be communicated. It is not concerned with how the data is created, read or processed by measurement software, data processing software, spreadsheets, etc. All data is communicated as an XML document. 1) Commission Internati

37、lour-measurement instrumentation. Care should be exercised to ensure that there are no other standards specific to the application area or industry that could be applied. 5 Terminology The terms used to describe a valid measurement record form two sections. The first section, A, is the sample-identi
38、fication section and is common to all measurements. It has descriptive information concerning the sample to be measured. The second section is made up of one or more data blocks, B to G, each representing a specific set of measurement data. Multiple measurement data blocks are useful when, for examp
39、le, a sample has either been measured separately for two or more geometries, or simultaneously using two or more geometries (e.g. in the case of a multi-angle measuring instrument). Generally, the multiple data blocks will be of the same type. Examples of valid data records are ABB or ACCCCC or ABBC
40、. In each section, the headings of each parameter used for communication are given and then explained in the table below it. Since each parameter is optional, if omitted, they will either take on the default value (as indicated in the following descriptions) or, where no default is specified, should
41、 be regarded as undefined or not applicable. 6 Structure A file containing measurement data would normally be structured as shown in Figure 1. This structure allows multiple data blocks within a single exchange file as described in Clause 5. Sample identification Measurement data block 1 Measurement
42、 data block 2 Measurement data block N Figure 1 Structure of a data measurement file If more than one sample is to be measured then a complete data file shall be assembled for each sample. Figure 2 shows the hierarchy between the various components of the colorimetric data exchange file. This allows
43、 for a description of the sample, spectral measurements and colorimetric measurements. The lower part of Figure 2 shows the relationship between the various parameters that can be associated with each measurement.

Unique identifier Text Identifier generated by measurement software. Ideally, this would be created from instrument serial number and a date/time
47、 stamp. Comment Text Area for the user to add any other information that he/she may wish to transmit. Colour preview Numeric hexadecimal The colour preview contains an approximate representation of the colour specified using the sRGB colour space and written as six hexadecimal digits: e.g. #FF0000 (
48、red). There may be multiple previews if, for example, the record contains multi-angle or both specular included and excluded data. The colour preview is only meant to provide a visual approximation for sample identification and should not be used to transmit actual data. 6.2 Measurement data block T
49、here are six possible measurement data blocks that can be associated with a sample. At least one of these must follow the sample block. When a sample has, for example, either been measured separately using two or more geometries or simultaneously for two or more geometries, then there follows a measurement data block for each geometry. 6.2.1 Spectral reflectance measurement (B) The measurement, as a function of wavelength, of the ratio of the reflected radiant or luminous flux to the incident flux in
