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. 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.

International 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. Publication 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 rights.

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 being 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 parts is given in ISO 105‑A01.

This European Standard was approved by CEN on 27 August 2007.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and 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.

1 Scope

This part of ISO 105 specifies a method intended for assessment of the potential to phenolic 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 intended 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.
