BS ISO 10617:2010 pdf free download Textiles — Standard data format for colorimetric communication — Textiles and related measurements
1Scope
This International Standard is primarily concerned with the exchange of the spectral data,which is thefundamental data behind the colour being communicated.
This International Standard provides a standard format for the interchange of data between a colorimetricmeasurement 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 to 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 colourreproduction industries.

4Principle
This International Standard describes the terms used in the colorimetric data exchange format (cdf). It showsthe order of the fields and how the format is laid out.None of the fields in the format are mandatory; therequisite field for the term can be left blank, in which case a default value is assumed. It should, however, benoted that the more information that is provided with the measurements, the greater the confidence that therecipient can have in the data.
The format described is concerned solely with the data to be communicated. lt is not concerned with how thedata is created, read or processed by measurement software, data processing software, spreadsheets, etc.Alldata is communicated as an XML document.
While this linternational Standard has been developed with the support of the textile industry, it can be appliedin any industry that uses colour-measurement instrumentation.Care should be exercised to ensure that thereare 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-identification section and is common to all measurements. lt has descriptive information concerning thesample to be measured. The second section is made up of one or more data blocks,B to G, eachrepresenting a specific set of measurement data.Multiple measurement data blocks are useful when, forexample, a sample has either been measured separately for two or more geometries, or simultaneously usingtwo or more geometries (e.g. in the case of a multi-angle measuring instrument). Generally , the multiple datablocks will be of the same type.Examples of valid data records are ABB or AcCCCC or ABBC.
In each section, the headings of each parameter used for communication are given and then explained in thetable below it.Since each parameter is optional, if omitted,they will either take on the default value (asindicated in the following descriptions) or, where no default is specified, should be regarded as undefined ornot applicable.
6 Structure
A file containing measurement data would normally be structured as shown in Figure 1.This structure allowsmultiple data blocks within a single exchange file as described in Clause 5.
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 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.

This section is composed of text identifying and describing the sample being measured. It is the first section to be communicated and is followed by one or more measurement data blocks. See Table 1 .
