SIST EN ISO 105-A08:2002 is the Slovenian adoption of EN ISO 105-A08:2002, based on ISO 105-A08:2001. It gives the vocabulary for colour measurement used throughout ISO 105, so textile laboratories, manufacturers, quality teams and buyers can use the same terms when describing and comparing colour data.
What does SIST EN ISO 105-A08:2002 specify?
SIST EN ISO 105-A08:2002 specifies the terms and definitions for colour measurements used throughout ISO 105. The definitions are intended only for use within the ISO 105 context, so the standard is a controlled vocabulary rather than a test method.
The document is organized into:
- Clause 1 - Scope
- Clause 2 - Terms and definitions
- Bibliography - related ISO 105 parts
What are the key requirements of SIST EN ISO 105-A08:2002?
SIST EN ISO 105-A08:2002 is mainly a terminology standard, so its key content is the approved wording for colour measurement concepts used in textile colour-fastness work.
- Clause 2.2 - CIE 1976, L, a, b* colour space (CIELAB)**: This defines the colour space used to express lightness and opponent colour axes. In practice, it is the common framework for reporting measured colour values.
- Clause 2.3 - CIE 1976, L, a, b* colour difference**: This defines colour difference as the distance between test and reference specimens in CIELAB space. In practice, it supports single-number colour comparison between samples.
- Clause 2.4 to 2.7 - CIE chromaticity coordinates, standard observer data, standard illuminant data and tristimulus values: These terms describe the CIE basis for colour measurement and calculation. In practice, they tell users which observer and illuminant conditions their colour data refer to.
- Clause 2.9 and 2.24 - colorimeter and spectrophotometer: The standard distinguishes instruments that measure colour directly in tristimulus terms from instruments that measure reflectance or transmittance by wavelength. In practice, this matters when selecting equipment and interpreting results.
- Clause 2.14 - grey scale: The grey scale is used for visual assessment of colour change or staining in fastness testing, with notes pointing to ISO 105-A02 and ISO 105-A03. In practice, it supports consistent human rating of test specimens.
- Clause 2.21 to 2.23 - spectral power distribution, spectral reflectance and spectral transmittance: These define how radiation from a source and material response are described by wavelength. In practice, they underpin instrument measurements and colour calculations.
- Clause 2.13, 2.19, 2.25 and 2.26 - fluorescent whitening agent, photochromism, standard depth scale and tinctorial strength: These terms describe colourants, reversible light-induced colour change, depth comparison and colouring effectiveness. In practice, they help users describe dyeing behaviour and compare coloured materials on a uniform basis.
- Clause 2.16 to 2.18 and 2.28 to 2.29 - IR radiation, perfect reflecting diffuser, visible radiation and whiteness: These terms set the measurement ranges and reference conditions used in colour work. In practice, they support calibration, lighting conditions and interpretation of near-white materials.
What terms does SIST EN ISO 105-A08:2002 define?
SIST EN ISO 105-A08:2002 defines the core vocabulary for colour measurement in ISO 105.
- chroma - the attribute that shows how far a colour departs from a grey of the same lightness.
- CIE 1976, L, a, b* colour space (CIELAB)** - a three-dimensional colour space based on CIE tristimulus values.
- CIE tristimulus values - the three reference colour amounts used to match a colour stimulus under defined conditions.
- colorimeter - an instrument that measures colour directly in tristimulus values.
- fluorescent whitening agent (FWA) - a colourant that absorbs near-ultraviolet radiation and emits violet-blue radiation.
- grey scale - a series of neutral chip pairs used to assign visual ratings in fastness testing.
- spectral power distribution (SPD) - the wavelength distribution of radiation from a source or illuminant.
Who uses SIST EN ISO 105-A08:2002?
SIST EN ISO 105-A08:2002 is used by textile testing laboratories, colour measurement specialists, dyehouses, quality managers and buyers who need a shared vocabulary for colour-fastness work. It is useful whenever a report, specification or test result needs to describe colour change, staining, instrument readings or visual assessment in ISO 105 terms.
Which standards are used with SIST EN ISO 105-A08:2002?
| Standard | Contribution |
|---|---|
| ISO 105-A01 | General principles of testing and the complete list of ISO 105 parts |
| ISO 105-A02 | Grey scale for assessing change in colour |
| ISO 105-A03 | Grey scale for assessing staining |
What does the SIST EN ISO 105-A08:2002 document contain?
SIST EN ISO 105-A08:2002 contains a vocabulary list of 29 colour-measurement terms, each with a definition and, where helpful, a note on usage. The notes explain CIE observer data, standard illuminants such as A, C and D, and the F series of recommended illuminants.
The document also defines measurement concepts such as spectral reflectance, spectral transmittance, visible radiation, UV radiation and IR radiation, which helps users state the measurement basis clearly. It includes terms for colour perception, such as lightness, hue, whiteness and depth, which are commonly used when comparing textile specimens.
For instrument work, the standard describes the role of colorimeters and spectrophotometers, and for visual assessment it explains the grey scale used in fastness testing. The bibliography points readers to ISO 105-A01, ISO 105-A02 and ISO 105-A03 for related ISO 105 guidance.

Foreword
ISO (the International Organization for Standardization) 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 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 Standards 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 casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 105 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 105-A08 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee
SC 1, Tests for coloured textiles and colorants.
ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication
dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the respective part
letter and by a two-digit serial number (e.g. “Section A01”). These sections are now being republished as separate
documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete list of
these parts is given in ISO 105-A01.
