Textiles - Tests for colour fastness - Part B06: Colour fastness and ageing to artificial light at high temperatures: Xenon arc fading lamp test (ISO 105-B06:2020)

This document specifies a method for determining the colour fastness and ageing properties of all kinds
and forms of dyed and printed textiles and/or other organic substrates under the action of an artificial
light source representative of natural daylight (D65), and under the simultaneous action of heat. Of the
five different sets of exposure conditions specified (see 7.1.1), four use D65, and the other one uses a
somewhat lower cut-off wavelength. The test method gives special consideration to the light and heat
conditions that occur in the interior of a motor vehicle.
The five different sets of conditions using the different optical filter systems specified can produce
different test results. Results from tests performed using different apparatus (instrument types) for the
same set of conditions and optical filter system are not comparable because comparable performance
has not been validated.

Textilien - Farbechtheitsprüfungen - Teil B06: Farbechtheit und Alterung gegen künstliches Licht bei hohen Temperaturen: Prüfung mit der Xenonbogenlampe (ISO 105-B06:2020)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Farbechtheit und des Alterungsverhaltens für alle Arten und Formen von gefärbten und bedruckten Textilien und/oder anderen organischen Substraten gegen die Einwirkung von künstlichem Licht, das dem natürlichen Tageslicht (D65) entspricht, und gegen die gleichzeitige Einwirkung von Wärme fest. Von den fünf verschiedenen beschriebenen Expositions¬bedingungsreihen (siehe 7.1.1) verwenden vier D65 und die andere arbeitet mit einer Filterkante bei etwas niedrigerer Wellenlänge. Das Prüfverfahren berücksichtigt insbesondere die Licht  und Wärmebedingungen, die im Innenraum eines Kraftfahrzeugs auftreten.
Die fünf verschiedenen festgelegten Expositionsbedingungen können unter Verwendung der verschiedenen optischen Filtersysteme zu unterschiedlichen Prüfergebnissen führen. Ergebnisse von Prüfungen, die mit unterschiedlichen Prüfgeräten (Gerätetypen) bei gleichen Expositionsbedingungen und mit dem gleichen optischen Filtersystem durchgeführt wurden, sind nicht vergleichbar, da die Vergleichbar¬keit der Ergebnisse bislang nicht bestätigt wurde.

Textiles - Essais de solidité des coloris - Partie B06: Solidité des coloris et vieillissement à la lumière artificielle à hautes températures: Essai avec lampe à arc au xénon (ISO 105-B06:2020)

Le présent document spécifie une méthode pour déterminer la solidité des coloris et les propriétés de vieillissement de tous les types et formes de textiles teints et imprimés et/ou autres supports organiques sous l'action d'une source de lumière artificielle représentative de la lumière naturelle du jour (D65) et sous l'action simultanée de la chaleur. Parmi les cinq différentes gammes de conditions d'exposition spécifiées (voir 7.1.1), quatre utilisent D65 et la cinquième, une transmission spectrale de longueur d'onde un peu inférieure. La méthode d'essai tient particulièrement compte des conditions d'éclairage et de chaleur de l'intérieur d'un véhicule à moteur.
Les cinq différentes gammes de conditions peuvent produire différents résultats d'essai à l'aide des différents dispositifs de filtration optique spécifiés. Les résultats obtenus pour des essais réalisés à l'aide d'appareillages (types d'instruments) différents pour une même gamme de conditions et un même dispositif de filtration optique ne sont pas comparables, car des performances comparables n'ont pas été validées.

Part B06:
Colour fastness and ageing to artificial light at high
temperatures: Xenon arc fading lamp test
1 Scope

This document specifies a method for determining the colour fastness and ageing properties of all kinds

and forms of dyed and printed textiles and/or other organic substrates under the action of an artificial

light source representative of natural daylight (D65), and under the simultaneous action of heat. Of the

five different sets of exposure conditions specified (see 7.1.1), four use D65, and the other one uses a

somewhat lower cut-off wavelength. The test method gives special consideration to the light and heat

conditions that occur in the interior of a motor vehicle.

The five different sets of conditions using the different optical filter systems specified can produce

different test results. Results from tests performed using different apparatus (instrument types) for the

same set of conditions and optical filter system are not comparable because comparable performance

has not been validated.

4 Principle
4.1 Light fastness test

A specimen to be tested is exposed to artificial light under prescribed conditions, along with a set of

blue wool references. The colour fastness shall be assessed by comparing the change in colour of the

test specimen with that of the references used, or with the grey scale in accordance with ISO 105-A02,

or by means of a colour measuring instrument in accordance with ISO 105-A05 after the specimen has

been exposed to a specified amount of radiant energy.
4.2 Ageing test

A specimen to be tested, together with blue wool reference 6 (see ISO 105-B02), is exposed to artificial

light under prescribed conditions. The change in colour of the specimen shall be evaluated on the grey

scale in accordance with ISO 105-A02, or by means of a colour-measuring instrument in accordance

with ISO 105-A05. Additional ageing criteria, such as mechanical properties, may also be evaluated.

Attention shall be paid to the principles for specifying and carrying out the tests, and for evaluating the

test results according to ISO 105-A01.
5 Reference materials and apparatus
5.1 Reference materials
5.1.1 General

Two different sets of blue wool references may be used. The two sets of references are not

interchangeable.
5.1.2 References 1 to 8

Blue wool references developed and produced in Europe are identified by the numerical designations

1 to 8. These references are blue wool cloths dyed with the dyes listed in Table 1. They range from 1

(very low colour fastness) to 8 (very high colour fastness) so that each higher-numbered reference is

approximately twice as fast as the preceding one (see Table 1).

5 CI acid blue 47
6 CI acid blue 23
7 CI solubilized vat blue 5
8 CI solubilized vat blue 8
NOTE References 1 to 4 are not applicable to this test.
5.1.3 References L2 and L4

Two blue wool references developed and produced in the United States are part of a series of eight

references identified by the letter L followed by the numerical designation. These references are for

the purpose of determining whether the xenon arc apparatus is operating within the desired range

concerning set of conditions No. 5 (see D.4).

5.2 Apparatus
5.2.1 Exposure apparatus

The exposure apparatus consists essentially of a climatic test chamber made of a corrosion-resistant

material and containing the optical light source, a filter system and holders for the test specimens.

5.2.2 Optical light source and filter system

One or more xenon arc lamps serve as the optical light source. The light for determining the hot

light fastness shall be filtered. Optical light filter systems are used for this purpose. Both absorption

filters and combinations of absorption and reflection filters shall be used according to Annex B and C,

depending on the test instrument being used. Irrespective of the type of filtration, the conditions listed

in Table 2 on the spectral energy distribution at the surface of the specimen shall be met.

As a percentage of the total irradiance in the wavelength range up to 800 nm.

The radiant power shall be chosen to ensure that the conditions given in 7.1.1 are fulfilled.

The irradiance shall not deviate by more than 10 % from the average over the entire area occupied by

the specimens and references.

Ageing causes the spectral energy distribution and irradiance to change during the service life of

the xenon arc lamps and optical filters. Replacement of the lamps and filters in accordance with the

manufacturers' instructions, allows the energy distribution and irradiance to be maintained. The

irradiance can also be adjusted to keep it constant. Manufacturers who supply an exposure apparatus

for use with this document should ensure that the conditions specified in 5.2 and 7.1.1 are met.

5.2.3 Radiometer for monitoring the exposure conditions

Since the irradiance at the surface of the specimen is affected by lamp intensity, lamp geometry and

the specimen rack (lamp to specimen distance), repeatability and reproducibility of exposure shall be

ensured by a monitoring radiometer which permits exposure to specified levels of irradiance (radiant

flux per unit area) at a point in the plane of the specimen rack (see B.3 and C.3).

5.2.4 Temperature sensors
5.2.4.1 Black-standard thermometer (BST) (for sets of conditions 1 to 3)

The black-standard thermometer shall consist of a plain stainless-steel plate, measuring about

70 mm × 40 mm and with a thickness of about 0,5 mm, whose temperature is measured by a thermal

resistor, with good heat-conducting properties fitted to the reverse side. The metal plate is fixed to a

plastic plate so that it is thermally insulated. It is coated with a black layer which has an absorption of at

least 95 %, even in the infrared region.
5.2.4.2 Black-panel thermometer (BPT) (for sets of conditions 5 and 6)

The black-panel thermometer shall consist of a metal plate approximately 70 mm wide, 150 mm

long, and 1 mm thick to which is fastened a thermal resistor whose sensitive portion is centred both

horizontally and vertically on the panel, the entire system being covered with a non-selective, infrared

absorbing black finish. The black finish shall have at least 95 % absorbance. The side of the panel not

facing the light source shall not be thermally insulated.
5.2.5 Opaque cardboard

This shall be of low sulfur content and free from fluorescent brightening agents, or other thin opaque

material, partially covering the specimens and references.
5.2.6 Grey scale for assessing change in colour
This shall be in accordance with ISO 105-A02.
5.2.7 Computerized spectral colour-measuring instrument
This is for evaluating the change in colour according to ISO 105-A05.
5.2.8 Polyester (PES) nonwoven fabric
2 2

This shall be at least 5 mm thick, with a mass per unit area of 100 g/m ± 5 g/m , for placing under the

specimens.
6 Preparation of specimens and exposure card

6.1 Test the specimens either with their own backing material or on a layer of polyester nonwoven

fabric (see 5.2.8). Unless agreed otherwise, the thickness of the underlying material shall be at least

5 mm. The limit specified in 6.4 shall be observed. The blue wool references shall be placed on white card

that does not contain fluorescent brightening agents.

6.2 Cut sections of at least 40 mm × 20 mm from flat materials and if necessary, attach them by their

narrow edges to white card that does not contain fluorescent brightening agents. For pile goods, carpets

and prints, cut the section to an appropriate size to include all colour components.

Wind yarns closely on to a card or mount on it in parallel lengths.

Form loose fibres into a nonwoven fabric or a fibrous web, of uniform thickness and surface and then

mount on the white card.

To facilitate handling, the specimens to be tested and the references may be mounted on one or more

cards as indicated in Figure 1.

6.3 The specimens and 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 the larger

pattern as against the narrower references (see 8.1).

6.4 For thick specimens or those with an underlay, the distances from the light source to the surface

of the specimens, the references and the black-standard thermometer or black-panel thermometer shall

not differ by more than about 5 mm.
