This European Standard shall be given the status of
14、a national standard, either by publication of an identical text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
15、countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
16、 Spain, Sweden, Switzerland and the United Kingdom. Endorsement notice The text of ISO 105-X18:2007 has been approved by CEN as a EN ISO 105-X18:2007 without any modification. 2 EN ISO 105-X18:2007 (E) 1 Scope This part of ISO 105 specifies a method intended for assessment of the potential to phenol
17、ic yellowing of textile materials. The method 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 in
18、tended as a screening test which, in practice, 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 indispe
19、nsable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、 terms and definitions apply. 3.1 phenolic 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 3 EN ISO 105
22、-X18:2007 (E) 4 Principle A test package is prepared, 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
23、, specimens and control fabric is then wrapped 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 i
24、ncubator/oven and test device, it is allowed to 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
25、parties. 5.2 If yarn or fibre is to be tested, 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
26、 cleaner that does not leave a residue (e.g. alcohol). 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 we
27、ight is removed during the test, the pressure applied 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
28、. 2/3, 2, etc.) on the control fabric. Use new 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 following sources: James H Heal b) identification of the test sample and sampling procedure, if required; c) the numerical grey scale rating for staining to express the potential of phenolic yellowness of materials. 6 EN ISO 105-X18:2007 (E)
