The work of preparing International Standards is normally carried out through ISO technical co
22、mmittees. 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 th
23、e International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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 least75% of the mem
24、ber bodies casting a vote. International Standard ISO105-B04was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. This fourth edition cancels and replaces the third edition (ISO 105-B04:1988), of which it constitutes a technical revisio
25、n. ISO105was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication dates between1978and 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 secti
26、ons 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.

27、 1 1 Scope This part of ISO105specifies a method intended for determining the resistance of the colour of textiles of all kinds, except loose fibres, to the action of weather as determined by exposure to simulated weathering conditions in a cabinet equipped with a xenon arc lamp. This method can be
28、used to determine if a textile is wet light-sensitive. NOTE 1General information on colour fastness to light is given in Annex A. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 105. At the time of pub
29、lication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO105are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of
30、currently valid International Standards. ISO 105-A01:1994, Textiles Tests for colour fastness Part A01: General principles of testing. ISO 105-A02:1993, Textiles Tests for colour fastness Part A02: Grey scale for assessing change in colour. ISO 105-B01:1994, Textiles Tests for colour fastness Part B
31、01: Colour fastness to light: Daylight. ISO 105-B02:1994, Textiles Tests for colour fastness Part B02: Colour fastness to artificial light: Xenon arc fading lamp test. 3 Principle Specimens of the textile are exposed under specified conditions to light from a xenon arc lamp and to water spray. At th
32、e same time, eight dyed blue wool references are exposed to light but are protected from water spray by a sheet of window-glass. The fastness is assessed by comparing the change in colour of the specimen with that of the references. If the method is used to determine if a textile is wet light-sensit
33、ive (see 4.3.1), the simultaneous exposure of references is unnecessary. In this case the assessment is performed by comparison with the grey scale in accordance with ISO 105-A02. 4 Reference materials and apparatus 4.1 Blue wool references The reference materials used in this test are those blue wo
34、ol references specified in ISO 105-A01 and ISO 105-A02, and subclause 4.1.1 of ISO B01:1994. 4.2 Apparatus 4.2.1 Xenon arc lamp apparatus 4.2.1.1 Light source, in a well-ventilated exposure chamber. The light source is a xenon arc lamp of correlated colour temperature5500 K to6500 K. 4.2.1.2 Light f
35、ilter, placed between the light source and the specimens and references so that the ultraviolet spectrum is steadily reduced. The glass used shall have a transmission of0% between290nm and300nm, rising to at least90% between380nm and750nm. 4.2.1.3 Heat filters, placed between the light source and th
36、e specimens and references so that the amount of infrared radiation is steadily reduced. The spectrum of the xenon arc contains an appreciable amount of infrared radiation which should be minimized by the heat filters to satisfy the temperature conditions. The filters shall be cleaned regularly to a
37、void undesirable reduction in light intensity by dirt. 4.2.2 Radiometer (when available/specified), for measuring irradiance and radiant exposure. Since irradiance at the test specimen face can vary as a function of lamp intensity and lamp-to-specimen distance, a monitoring radiometer may be used to
38、 control uniformity of exposure. The radiometer permits exposure to an established level of irradiation (radiant energy flux per unit area) at a point in the plane of the specimen rack (see Annex B). 4.2.3 Opaque cardboard, or other thin opaque material, for example thin sheet aluminium or cardboard
39、 covered with aluminium foil, or, in the case of pile fabrics, a cover that avoids surface compression. 4.2.4 Grey scale for assessing change in colour, in accordance with ISO 105-A02. 4.3 Exposure conditions The test specimens and the blue wool references are exposed simultaneously in the apparatus
40、 (4.2.1), the specimens to both light and water spray, and the references to light only. The air temperature in the chamber shall be measured with a thermometer whose sensitive portion is shielded from the direct radiation of the arc. The temperature in the test chamber shall not exceed40 C during t
41、he drying period. The temperature of the black panel, which is measured in the centre and under the same illumination as the specimens, shall not exceed that of the test chamber by more than20 C at the maximum drying period (black panel temperature, see ISO 105-B02:1994, subclause 4.2.3).EN ISO 105-
42、B04:1997 2 BSI 09-1999 The variation in light intensity over the area covered by specimens and references shall not exceed 10% of the mean. 4.3.1 Exposure of test specimens The specimens shall be subjected to the following accurately adjusted, reproducible weathering cycle: duration of spraying: 1 m
43、in; duration of drying: 29 min. For spraying the specimens, only completely ion-free water shall be used. It should be especially noted that this water shall not contain any metal salts. Tubing, tanks and spray jets shall be of corrosion-resistant material. If the method is used to determine if a te
44、xtile is wet light-sensitive, the weathering cycle shall be repeated for a total of16h testing. The specimens shall be mounted on a suitable holder. The specimens shall completely enclose the holder and the side to be assessed shall not be in contact with metal plates, other specimens, or backing fa
45、bric. NOTE 2The holders described in Textil-Rundschau, 18 (1963) 2, 76, photo 2, left, may be used. The manufacturer of these holders also supplies a case to protect the references. 4.3.2 Exposure of colour fastness references The blue wool references (4.1) shall be protected from the water spray by
46、 a shield of glass whilst being exposed to light from the same xenon arc lamp as the specimens. The transmission of the glass shall be0% between310nm and320nm, rising to at least90% between380nm and750nm. The glass case shall be well ventilated, i.e. there shall be an opening at the top and another
47、at the bottom to allow good circulation of air. 5 Test specimens 5.1 If the textile to be tested is fabric, prepare two specimens, each of a suitable size, mounted on holders or other equipment which will fit the weathering test equipment. 5.2 If the textile to be tested is yarn, knit or weave it in
48、to fabric and treat it as described in 5.1. Loose fibres are not suitable for weathering tests. 5.3 Mount strips of blue wool references on cardboard, (4.2.3), cover one-third of each as described in ISO 105-B02:1994, 7.2.1.2 and fix the mounted references under glass according to 4.3.2. 5.4 Unexpos
49、ed samples of original fabric identical to those being tested are required as references for comparison with the specimens during weathering. 6 Procedure 6.1 Procedure common to methods 1, 2 and 3 6.1.1 Place the specimens mounted on the holders (see 4.3.1) in the apparatus and expose them continuously to weathering following method 1, 2 or3 (see 6.2 to 6.4). 6.1.2 At the same time, expose the mounted and partially covered blue wool references (see 4.1 and5.3) to light in the glass case of the same apparatus (see 4.3.
