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 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 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 105-B02 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for
coloured textiles and colorants.
This fifth edition cancels and replaces the fourth edition (ISO 105-B02:1994), which has been technically
revised. It also incorporates ISO 105-B02:1994/Amd 1:1998 and ISO 105-B02:1994/Amd 2:2000.
ISO 105 was previously published in 13 “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 alpha-
numeric designations. A complete list of these parts is given in ISO 105-A01.

Colour fastness to artificial light: Xenon arc fading lamp test
1 Scope
This part of ISO 105 specifies a method intended for determining the effect on the colour of textiles of all
kinds and in all forms to the action of an artificial light source representative of natural daylight (D65).
The method is also applicable to white (bleached or optically brightened) textiles.
This method allows the use of two different sets of blue wool references. The results from the two
different sets of references may not be identical.

5.1 Reference materials
5.1.1 General
Either of two sets of blue wool reference may be used. The colour fastness ratings mentioned in this part
of ISO 105 are obtained by comparison with either blue wool references 1 to 8 (preferred in Europe) or
blue wool references L2 to L9 (preferred in America). The results from the two sets of references are not
interchangeable. Information on the relationship between the two sets of blue wool reference materials
can be found in ISO 105-B01:1994, 4.1.

5.1.2 Blue wool reference materials 1 to 8
Blue wool references developed and produced in Europe are identified by the numerical designation 1
to 8. These references are blue wool materials dyed with the dyes listed in Table 1. They range from 1
(very low colour fastness to light) to 8 (very high colour fastness to light) so that each higher-numbered
reference is approximately twice as fast as the preceding one.

Box 12215, Research Triangle Park, NC 27709-2215, USA.
5.1.3 Blue wool reference materials L2 to L9
Blue wool references developed and produced in America are identified by the letter L followed by the
numerical designation 2 to 9. These eight references are prepared by blending varying proportions of
wool dyed with CI Mordant Blue 1 (Colour Index, fourth edition, CI Constitution Number 43830) and
wool dyed with CI Solubilised Vat Blue 8 (Colour Index, fourth edition, CI Constitution Number 73801),
so that each higher-numbered reference is approximately twice as fast as the preceding reference.
Data in Annex C are presented to illustrate the relationship of each of the blue wool references on
exposure to fixed amounts of radiant energy.
5.1.4 Humidity-test control
The effective humidity can only be measured by determining the colour fastness to light of a specific
humidity-test control fabric (see 4.7).
5.2 Laboratory exposure devices
5.2.1 Light source
5.2.1.1 The exposure device shall provide for placement of specimens and any designated sensing
devices in positions that allow uniform irradiance from the light source
NOTE The spectral irradiance produced in an artificial accelerated light and weathering device is very
important. Ideally, the relative spectral irradiance produced by the device should be a very close match to that
of solar radiation, especially in the short wavelength UV region. Annex A provides information about important
benchmark solar spectra that can be used for comparing the spectral irradiance produced in the artificial
accelerated exposure to that for solar radiation.
5.2.1.2 Exposure devices shall be designed such that the variation in irradiance at any location in
the area used for specimen exposure shall not exceed ± 10 % of the mean. Procedures for measuring
irradiance uniformity are found in Annex B.

---------------------- Page: 13 ----------------------
SIST EN ISO 105-B02:2013
ISO 105-B02:2013(E)
NOTE The irradiance uniformity in exposure devices depends on several factors. The configuration of the
lamp with respect to the specimens on exposure, including the differences in distance between the lamp(s) and
the samples can affect uniformity of exposure. Deposits which can develop on the optical system and chamber
walls, and the type and number of specimens being exposed, can also have an affect on uniformity of exposure.
5.2.1.3 Periodic repositioning of the test specimens in the test chamber is recommended to ensure the
most consistent results.
5.2.1.4 Follow the apparatus manufacturer’s instructions for lamp and filter replacement.
5.2.1.4.1 Direct radiation from xenon burners contains considerable amounts of short-wavelength
ultraviolet radiation not present in daylight. Optical filters shall be fitted to minimize short-wavelength
light (less than 310 nm) in accordance with the requirements in Annex A. The xenon arc, when
appropriately filtered, produces radiation with a spectral power distribution that is a good simulation of
average daylight throughout the UV and visible region.
5.2.1.4.2 Infrared radiation levels can be attenuated by use of filters to allow some control of the
sample temperature.
5.2.1.5 It is preferred that the apparatus should be fitted with an irradiance sensing system. The
irradiance sensor (if fitted) shall be mounted so that it receives the same radiation as the specimen surface.
If it is not positioned in the specimen plane, it shall be calibrated for irradiance at the specimen distance.
5.2.1.5.1 The irradiance sensor (if fitted) shall be capable of measuring irradiance preferably in a specific
wavelength range (e.g. 300 nm to 400 nm), or in a narrow bandpass centred around a single wavelength
(e.g. 420 nm) and shall be calibrated at the wavelength range or single wavelength, as appropriate. The
measured wavelength or wavelength range shall be reported.
2
5.2.1.5.2 Where irradiance control is available, the irradiance shall be controlled at (42 ± 2) W/m in
2
the wavelength range 300 nm to 400 nm or (1,10 ± 0.02) W/(m .nm) at the wavelength 420 nm.
5.2.1.5.3 The irradiance sensor (if fitted) shall be calibrated in the emission region of the light
source used. Calibration shall be checked in accordance with the radiation-measuring and instrument
manufacturer’s instructions with compliance to ISO 9370.
5.2.1.6 The light source shall consist of a xenon arc lamp of correlated colour temperature 5500 K to
6500 K, the size of which will depend on the type of apparatus used.
5.2.1.7 The apparatus shall be fitted with a light filter placed between the light source and the specimens
so that the ultraviolet spectrum is steadily reduced. Annex A provides the transmission requirements for
the filter system used.
5.2.1.8 The apparatus shall be fitted with a heat filter placed between the light source and the specimens
so that the amount of infrared (IR) radiation contained in the xenon arc spectrum is steadily reduced.
5.2.2 Temperature (See A.3)
One of two types of black-coated temperature sensor shall be used, either a black-standard thermometer
or a black-panel thermometer (for more detail see A.3.) and the thermometer shall be mounted in the
same plane and orientation as the test specimen(s).
Note The preferred thermometer is the Black Standard Thermometer (BST).

5.2.3 Humidity
The presence of moisture can have a significant effect in accelerated laboratory exposure tests. The
apparatus shall have the means for providing and controlling moisture to specimens by humidification
of the chamber air. The quality of the water used to create the effective humidity shall be a minimum of
Grade 3 in accordance with ISO 3696.
5.2.4 Covers
Covers shall be made from thin opaque material, for example high-grade steel, thin sheet aluminium
or cardboard covered with aluminium foil, for partial covering of samples and references. The opaque
material shall neither react with the test specimens nor the test conditions and shall not itself produce
any change in colour of either the test specimen or the reference materials.
5.2.5 Colour matching lamps, in accordance with CIE Publication No. 51.
5.2.6 Assessment cabinet, complying with ISO 105-A01.
5.2.7 Sample mounting card, free of optical or fluorescent brightening agent.
5.2.8 Assessment mask, complying with ISO 105-A01. In order to obtain reliable test results using
ISO 105-A02, the test specimen(s) shall be masked with a material that is identical in colour to the sleeve
that is used to mask the grey scale (5.2.9).
5.2.9 Grey scale for assessing change in colour, complying with ISO 105-A02.
6 Preparation of test specimens
6.1 The size of the test specimen will depend on the number of specimens to be tested and on the shape
and dimensions of the specimen holders supplied with the apparatus.
Attention is drawn to the guidelines given in E.4.
6.2 The specimen may be a strip of cloth, yarn wound close together on a sample mounting card (5.2.7)
or laid parallel and fastened on a card, or a mat of fibres combed and compressed to give a uniform
surface and fastened on a card. Each exposed and unexposed area shall be not less than 10 mm × 8 mm.
6.3 To facilitate handling, the test specimen(s) to be tested and similar strips of the references may be
mounted on one or more cards as indicated in Figures 2, 3, 4 or 5.
6.4 The covers (5.2.4) shall make close contact with the surface of the unexposed areas of the specimens
and the references, in order to give a sharp line of demarcation between exposed and unexposed areas,
but shall not compress the specimen unnecessarily.
6.5 The specimens to be tested and the blue wool references shall be of equal size and shape in order to
avoid errors in assessment due to overrating the visual contrast between exposed and unexposed parts
on a larger pattern as against a narrower reference.
6.6 When testing specimens of appreciable thickness, the references shall be arranged so that they
are the same distance from the light source as the upper surface of the test specimens. Covers for the
unexposed portions shall avoid surface compression.
Textiles of appreciable thickness which have fibres that may shift position or texture which may make
evaluation of small areas difficult, shall be tested with an exposed area not less than 50 mm × 40 mm
and preferably larger.
