ISO 105-B04: 1994(E) 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. Esch 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. 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. International Standard ISO 105-B04 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and coloran ts. This fourth edition cancels and replaces the third edition (ISO 105-B04:1988), of which it constitutes a technical revision. ISO 105 was previously published in thirteen “Parts”, each designated by a letter (e.g. “Part A”), with publication dates between 1978 and 1985. Esch part contained a series of “sections”, each designated by the re- spective part letter and by a two-digit serial number (e.g. “Section AO1 “). These sections are now being republished as separate documents, them- selves designated “Parts” but retaining their earlier alphanumeric desig- nations. A complete list of these Parts is given in ISO 105-AOI . Annexes A and B of this part of ISO 105 are for information only. 0 ISO 1994 All rights reserved.

At the same time, eight dyed blue wool refer- ences 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-sensitive (see 4.3.1), the simultaneous exposure of references is unnecessary. In this case the as- sessment 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 wool references specified in ISO 105-AO1 and ISO 105-A02, and subclause 4.1 .l of ISO BOI :1994. 4.2 Apparatus 4.2.1 Xenon arc lamp apparatus. 4.2.1.1 Light Source, in a weil-ventilated exposure chamber. The light Source is a Xenon arc lamp of cor- related colour temperature 5 500 K to 6 500 K. 1 SIST EN ISO 105-B04:1999
ISO 105-B04:1994(E) 0 ISO 4.2.1.2 Light filter, placed between the light Source and the specimens and references so that the ultra- violet spectrum is steadily reduced. The glass used shall have a transmission of 0 % between 290 nm and 300 nm, rising to at least 90 % between 380 nm and 750 nm. 4.2.1.3 Heat filters, placed between the light Source and the specimens and references so that the amount of infrared radiation is steadily reduced. The spectrum of the Xenon arc contains an appreci- able amount of infrared radiation which should be minimized by the heat filters to satisfy the tempera- ture conditions. The filters shall be cleaned regularly to avoid 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 tan vary as a function of lamp intensity and lamp-to-specimen distance, a monitoring radiometer may be used to control uniformity of exposure. The radiometer per- mits 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 ma- terial, for example thin sheet aluminium or cardboard 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 (4.2.1), the specimens to both light and water Spray, and the ref- erences 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 exceed 40 “C during the drying period. The temperature of the black Panel, which is meas- ured in the centre and under the same illumination as the specimens, shall not exceed that of the test chamber by more than 20 “C at the maximum drying period (black Panel temperature, see ISO 105-B02: 1994, subclause 4.2.3). The Variation in light intensity over the area covered by specimens and references shall not exceed +lO % 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 min; - duration of drying: 29 min. For spraying the specimens, only completely ion-free water shall be used. lt 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 textile is wet light-sensitive, the weathering cycle shall be repeated for a total of 16 h 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 fabric. NOTE 2 The holders described in ~exM?undschau, 18 (1963) 2, 76, Photo 2, left, may be used. The manufacturer of these holders also supplies a case to protect the refer- ences. 4.3.2 Exposure of colour fastness references The blue wool references (4.1) shall be protected from the water Spray by a shield of glass whilst being ex- posed to light from the same Xenon arc lamp as the specimens. The transmission of the glass shall be 0 % between 310 nm and 320 nm, rising to at least 90 % between 380 nm and 750 nm. The glass case shall be weil ventilated, i.e. there shall be an opening at the top and another 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 hold- ers or other equipment which will fit the weathering test equipment. 5.2 If the textile to be tested is yarn, knit or weave it into fabric and treat it as described in 5.1. Loose fibres are not suitable for weathering tests. 2 SIST EN ISO 105-B04:1999
Q ISO ISO 105-B04:1994(E) 5.3 Mount Strips of blue wo01 references on card- board, (4.2.3), cover one-third of each as described in ISO 105-B02:1994, 7.2.1.2 and fix the mounted refer- ences under glass according to 4.3.2. 5.4 Unexposed 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 con- tinuously to weathering following method 1, 2 or 3 (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 and 5.3) to light in the glass case of the Same apparatus (see 4.3.2). 6.1.3 Only one side of the test specimen shall be exposed to weathering and light. 6.1.4 Whilst the specimens are drying, the air in the test chamber shall not be moistened. NOTE 3 The actual conditions of the weathering test de- pend on the kind of test apparatus used. 6.1.5 Contrary to stipulations for the outdoor expo- Sure test, the speciments shall not be washed after the weathering test. 6.2 Method 1 6.2.1 This method is considered most satisfactory and is mandatory in cases of dispute over the nu- merical rating. The basic feature is the control of the exposure periods by inspection of the specimen and, therefore, one set of blue wool references is required for each specimen under test. lt is therefore imprac- ticable when large numbers of specimens have to be tested concurrently; in such cases, method 2 (see 6.3) shall be used. 6.2.2 Expose the specimens and the blue wo01 ref- erences under the conditions described in 6.1 until the contrast between the exposed specimens and a por- tion of the original fabric (5.4) is equal to grey scale grade 3. Remove one of the specimens and cover a second one-third of the references with an additional opaque cover. 6.2.3 Continue the exposure until the contrast be- tween the remaining specimen and a portion of the unexposed original fabric is equal to grey scale grade 2. If blue wool reference 7 fades to a contrast equal to grey scale grade 4 before the contrast be- tween the specimen and the Portion of the original fabric is equal to grey scale grade 2, the exposure may be concluded at this Stage and the remaining specimen and the reference removed. 6.2.4 Prepare both specimens, and a Portion of the original fabric for assessment (see 6.4 and 6.5). 6.2.5 If textiles are to be examined for wet light- sensitivity, a 16 h testing period shall be used Prior to assessment. 6.2.6 Assess the colour fastness to weathering in accordance with the method given in 7.1 to 7.3. 6.3 Method 2 6.3.1 This method should be used when the number of specimens to be tested simultaneously is so large that method 1 is impracticable. The basic feature of this method is the control of the exposure period by inspection of the blue wool references, which allows a number of specimens differing in weathering fast- ness to be tested against only one set of references, thus conserving supplies of the latter. 6.3.2 Expose the specimens and the blue wool ref- erences under the conditions described in 6.1 until the contrast between the exposed and unexposed portions of reference 6 is equal to grey scale grade 4. At this Stage, remove one specimen from each pair and cover a second one-third of the blue wool references with an additional opaque cover. 6.3.3 Continue the exposure until the contrast be- tween the fully exposed and unexposed portions of reference 7 is equal to grey scale grade 4. Remove the remaining specimens and the references. 6.3.4 Prepare the exposed specimens and a Portion of the original fabric (5.4) from each specimen for as- sessment (see 6.5 and 6.6). 6.3.5 Assess the colour fastness to weathering of each specimen in accordance with the method given in 7.1 to 7.3.

The specimens should undergo weathering for the time required for exposure to the specified level of radiant energy, then removed together with the blue wool references and evaluated in accordance with clause 7. 6.5 Drying Before mounting the tested specimens for assess- ment, dry them in air at a temperature not exceeding 60 “C. 6.6 Mounting for assessment Trim and mount the tested specimens so that they measure at least 15 mm x 30 mm, one on each side of a Portion of the original fabric (5.4) which has been trimmed to the Same size and shape as the speci- mens.
