16、on 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 ha
17、s 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. Inte
18、rnational 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. Publica
19、tion 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 rig
20、hts. ISO 105-X18 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105-X18 is part of a series of standards which were originally published as 13 “parts”, under the general title Textiles Tests for colour fastness, each part be
21、ing designated by a letter (for example “Part A”), the publication dates being between 1978 and 1985. Each part included a series of “sections”, each designated by the letter corresponding to the part and by a series number with two figures (for example, “Section A01”). A complete list of these part
22、s is given in ISO 105-A01. EN ISO 105-X18:2007blank1Textiles Tests for colour fastness Part X18: Assessment of the potential to phenolic yellowing of materials 1 Scope This part of ISO 105 specifies a method intended for assessment of the potential to phenolic yellowing of textile materials. The met
23、hod is specific to phenolic yellowing and does not cover the many other possible causes of yellow discolouration found on textile materials. NOTE Use of the method does not guarantee that the materials tested will not exhibit yellowing in some form. It is intended as a screening test which, in pract
24、ice, has been found to significantly reduce the number of complaints of phenolic yellowing by enabling corrective action to be taken with materials which, after testing, exhibit yellowing. 2 Normative references The following referenced documents are indispensable for the application of this documen

27、 yellowing discolouration of textile materials caused by the action of oxides of nitrogen and phenolic compounds, which lead to the production of a yellow colour 3.2 potential to phenolic yellowing possibility or capability of phenolic yellowing EN ISO 105-X18:20072 4 Principle A test package is pre
28、pared, consisting of test papers, test specimens and one control fabric. Each specimen and the control fabric are individually placed between a folded test paper placed between two glass plates in a horizontal formation. The stack of plates, test papers, specimens and control fabric is then wrapped
29、firmly in BHT (butyl hydroxytoluene) free polyethylene film to create an airtight package. The package is loaded in a test device, which is placed in an incubator/oven, for a specified time at a specific temperature. On removal of the package from the incubator/oven and test device, it is allowed to
30、 cool. The package is opened, and the control fabric and specimens are assessed immediately by comparison with the grey scale for assessing staining. 5 Test specimens 5.1 Select the specimens to represent the sample, or as agreed between the interested parties. 5.2 If yarn or fibre is to be tested,
31、then take a mass of the yarn or loose fibre that is sufficient to form by hand a mat of material approximately 100 mm 30 mm. 6 Apparatus 6.1 Glass plates, each (100 1) mm (40 1) mm (3 0,5) mm. Clean the glass plates thoroughly between each test, using a cleaner that does not leave a residue (e.g. al
32、cohol). 6.2 Incubator or oven, to maintain (50 3) C. 6.3 Test device, consisting of a stainless-steel frame into which a weight of mass (5 0,1) kg and base of minimum (60 115) mm is closely fitted. The test device shall be constructed so that, if the weight is removed during the test, the pressure a
33、pplied to the specimens remains unchanged. 7 Materials 7.1 Test papers1), (100 2) mm (75 2) mm, density (88 7) g/m2at 20 C, of 98 % pure cellulose treated with 0,1 % 2,6-di-tert-butyl-4-nitrophenol to give a Grey Scale for Staining Grade 3 or worse (i.e. 2/3, 2, etc.) on the control fabric. Use new
34、test papers for each test. Store the test papers in resealable aluminium foil packaging in a cool dry environment or conditioned laboratory. Use within 6 months of opening. NOTE It is advisable to wear protective gloves when handling. 1) Test papers and control fabrics may be purchased from the foll
