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. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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.

This method is applicable to all materials which are used in intimate contact to adhesives which are used to bond them. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

NOTE The necessary mass depends of the area of the test specimen to get the same pressure. EXAMPLE Area of test specimen = 30 mm × 20 mm = 600 mm 2 Mass = pressure × area © ISO 2016 – All rights reserved 1BS EN ISO 17701:2016ISO 17701:2016(E) Mass = 5,2 kPa × 600 mm 2= 5 200 Pa × 600 mm 2= 5 200 kg × m −1× s −2× 6 × 10 −4m −2 Mass = 3,12 kg × m × s −2= 3,12 N A mass of 3,12 N (these are 0,318 kg) is necessary to get a pressure of 5,2 kPa. Please note that the mass of one glass plate has to be subtracted: mass = 318 g – 50 g = 268 g. If the area of the test specimen is 50 mm × 40 mm, a mass of 1,060 kg is necessary to get the same pressure. Please note that the mass of one glass plate has to be subtracted: mass = 1 060 g – 50 g = 1 010 g. 4.4 Oven, without a door or glass window, heated to 60 °C ± 2 °C. 4.5 Colorimeter to measure the colour of the test specimen and the reference specimen to convert the results in CIE colour values and to calculate automatically the CIELAB colour differences in accordance with CIE 15. The colorimeter has to be calibrated with a white standard (normal light D 65, normal observer 10°, measure geometry dl8°). 4.6 Grey scales with half step rating for assessing change in colour and degree of staining complying with ISO 105-A02 and ISO 105-A03, respectively. 4.7 Artificial lighting conditions as specified in ISO 105-A01 or north daylight. 5 Sampling and conditioning Store the test materials in a conditioned standard atmosphere as specified in ISO 18454 for a minimum of 24 h prior to testing. 5.1 Testing for colour migration between materials Cut two test specimens from each material, the dark-coloured material and the light-coloured material with a size of 30 mm× 20 mm (±2 mm) as minimum. One of each type of test specimen is the reference sample. If there are insufficient materials, smaller samples may be used and a proportionally lower mass than 1 000 g ± 10 g to maintain the same contact pressure. 5.2 Testing for the effect of adhesives Cut two samples of the test material with a size of (50 ± 2) mm × (50 ± 2) mm. One of the test specimens is the reference sample. Coat the centre of the surface, to which the adhesive would be applied in production with the adhesive under test, so that the coating covers approximately 75 % of the area of the test specimen. Use a quantity of adhesive that is judged to be representative of that to be used in production. Allow the adhesive to dry at room temperature. 5.3 Testing for the effect of adhesives in laminate Cut two samples from each material to be laminated together with a size of (50 ± 2) mm × (50 ± 2) mm, when testing for the effect of an adhesive within a laminate. One of each type of test specimen is the reference sample. 5.3.1 When testing for the effect of adhesives within a laminate, where a wet bond is used in production, place the two materials together and press by hand to form a bonded assembly and allow the adhesive to dry at room temperature.2 © ISO 2016 – All rights reservedBS EN ISO 17701:2016ISO 17701:2016(E) 5.3.2 When testing for the effect of adhesives within a laminate where the bond is formed with dry adhesive films, join the two materials using a technique similar to that used in production. 5.4 Testing components such as soling 5.4.1 Prepare by suitable means, a test specimen of uniform thickness from the sole or other component. 5.4.2 Cut a test specimen from the material and two pieces of the second test material (5.1, one as reference sample). NOTE Specimens can be taken either from materials likely to be used for uppers or from made up uppers or finished footwear. 6 Test method 6.1 Principle Either two dissimilar materials are placed in intimate contact, or a single piece of material, coated with a product such as an adhesive, or laminated materials are placed between glass plates. The assembly is stored in the dark for a prescribed period at an elevated temperature. The test specimens are then examined for any discolouration compared with unexposed reference samples. Discolouration indicates that the materials are likely to discolour under normal service conditions. 6.2 Procedure The CIE values of the colour of all test specimens have to be measured with the colorimeter (including the reference samples). Store the reference samples darkly in standard conditioned atmosphere as specified in ISO 18454. 6.2.1 For assemblies of two materials not joined together with adhesive. 6.2.1.1 Place the first test specimen centrally on a glass plate (see 4.2) with its contact face uppermost. 6.2.1.2 Place the other test specimen with its contact face lowermost on the first specimen. 6.2.1.3 Place the remaining glass plate (see 4.2) centrally on top of the specimens. 6.2.2 For adhesive coated single materials and laminates, place the test specimen between the two glass plates. 6.2.3 Place the mass (see 4.3) symmetrically on the top glass plate (see 4.2). 6.2.4 Place the assembly (see 6.2.1 or 6.2.2) in the dark test environment at (60 ± 2) °C (see 4.4). 6.2.5 After 24 h, remove the assembly from the test environment. 6.2.6 For assemblies of two not joined materials, separate the two materials and compare their contact faces to the reference samples. Assess in accordance with 6.2.8. 6.2.7 For adhesive coated single materials and laminates, remove the test specimen and compare the face not coated with adhesive to unexposed material. Assess in accordance with 6.2.8.© ISO 2016 – All rights reserved 3BS EN ISO 17701:2016ISO 17701:2016(E) 6.2.8 Measure the CIE values (in accordance with CIE 15) of the colour with the colorimeter (see 4.5). The use of the artificial lighting or north daylight is another method (4.7). Assess any loss of colour by comparing the contrast in colour between tested and non-tested material with the ratings on the grey scale. 6.2.8.1 Measure any loss of colour by comparing the colour between tested and non-tested material for assessing the change in colour. 6.2.8.2 Measure any transfer of colour by comparing the colour between tested and non-tested material for ass
