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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

The committee responsible for this document is ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. This third edition cancels and replaces the second edition (ISO 105-G01:1993), which has been technically revised. It also incorporates the Technical Corrigendum ISO 105-G01:1993/Cor 1:1995. The main technical changes are the following: a) the test-control fabric dyed with Disperse Blue 3 was deleted; b) the test-control fabric dyed with Disperse Violet 1 and the test-control fabric dyed with Disperse Blue 56 were added. ISO 105 consists of many parts designated by a part letter and a two-digit serial number (e.g. A01), under the general title Textiles — Tests for colour fastness. A complete list of these is given in ISO 105-A01.iv © ISO 2016 – All rights reservedBS EN ISO 105-G01:2016INTERNATIONAL ST ANDARD ISO 105-G01:2016(E) Textiles — Tests for colour fastness — Part G01: Colour fastness to nitrogen oxides 1 Scope This part of ISO 105 specifies two methods for determining the resistance of the colour of textiles of all kinds and in all forms to the action of nitrogen oxides produced during combustion of gas, coal, oil, etc., and when air is passed over heated filaments. The two tests differ in severity; one or both of them are used, depending on the result obtained (7.2.4). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 105-A02, Textiles — Tests for colour fastness — Part A02: Grey scale for assessing change in colour ISO 105-F02, Textiles — Tests for colour fastness — Part F02: Specification for cotton and viscose adjacent fabrics ISO 139, Textiles — Standard atmospheres for conditioning and testing ISO 3696, Water for analytical laboratory use — Specification and test methods 3 Principle Specimens of textiles are exposed to nitrogen oxides in a closed container until either one or three test-control fabrics exposed simultaneously with the test specimens have changed in colour to a predetermined extent. The change in colour of each specimen is assessed with the grey scale. 4 Apparatus and materials 4.1 Exposure chamber, see Annex A. 4.2 Nitric oxide, from a commercially supplied cylinder or a generator (see Annex B). WARNING — Nitric oxide is toxic. The maximum concentration in a working room should not exceed 6,7 mg/m 3 . 4.3 Sulfuric acid, containing 1 100 g/l of H 2 SO 4(relative density 1,603). 4.4 Sodium nitrite (NaNO 2 ), saturated solution in grade 3 water (4.13). 4.5 Sodium hydroxide, dilute solution (approximately 100 g/l of NaOH). © ISO 2016 – All rights reserved 1BS EN ISO 105-G01:2016ISO 105-G01:2016(E) 4.6 Urea solution, containing 10 g/l of urea (NH 2 CONH 2 ), buffered to pH 7 by the addition of 0,4 g/l of sodium dihydrogen orthophosphate dihydrate (NaH 2 PO 4 ·2H 2 O) and 2,5 g/l of disodium hydrogen orthophosphate dodecahydrate (Na 2 HPO 4 ·12H 2 O), and containing 0,1 g/l or less of a rapid-wetting surface-active agent, for example, sodium dioctyl sulfosuccinate. 4.7 Test-control fabric 4.7.1 Test-control fabric dyed with Disperse Violet 1 A woven filament acetate is uniformly dyed in an open-width dyeing machine with 0,4 % (on mass of fabric) Cl Disperse Violet 1 (Colour Index, Third Edition) in a dye-bath containing 1 g/l of a dispersing agent at a liquor ratio of 10:1. The fabric construction has both a taffeta and a satin side; for this test procedure, only the taffeta side will be considered. The resistance of the test-control fabric to the action of nitric oxide should not be varied between the new lots. The supplier should confirm the performance of the new lot. 1) 4.7.2 Test-control fabric dyed with Disperse Blue 56 A woven filament acetate is uniformly dyed in an open-width dyeing machine with 0,8 % (on mass of fabric) CI Disperse Blue 56 (Colour Index, Third Edition) in a dye-bath containing 0,5 ml/l of a dispersing agent at a liquor ratio of 42:1. The fabric construction has both a taffeta and a satin side; for this test procedure, only the taffeta side will be considered. The resistance of the test-control fabric to the action of nitric oxide should not be varied between the new lots. The supplier should confirm the performance of the new lot. 2) 4.8 Standard of fading 4.8.1 Standard fading fabric for test-control fabric dyed with Disperse Violet 1 The regenerated cellulose woven taffeta is a fabric of similar appearance to the test-control fabric (4.7.1), dyed to match an average of faded test-control fabric. 3)4.8.2 Standard of fading for test-control fabric dyed with Disperse Blue 56 It is considered that the standard of fading is completed when a faded test-control fabric (4.7.2) is observed to have a contrast equal to grade 3-4 on the grey scale. 4.9 Syringe, for injecting oxide into the exposure chamber (4.1). A medical syringe is best suited to the injection of the nitric oxide. For a larger exposure chamber, the gas can also be measured and transferred from the nitric oxide reservoir to the exposure chamber by means of a gas burette. 4.10 Undyed fabric, of the same kind(s) of fibre as the test specimen. 1) Test-control fabric dyed with Disperse Violet 1 is commercially available from Testfabrics, Inc.

When an adhesive is used, this shall be allowed to dry properly. 7.1.2 Up to 12 test specimens, each measuring 40 mm × 100 mm, may be mounted in this way for one test. If fewer test specimens are to be tested, fill up with cuttings of undyed fabric of the same kind to the total number of 12. The test-control fabric is fastened to the holder. Condition the test specimens and test-control fabric for at least 12 h in the atmosphere specified in Clause 5. 7.1.3 Place the frame with the test specimens inside the glass cylinder and then place the bell-jar on top; put the holder with the test-control fabric through the top plug-hole. 7.1.4 Adjust the rotational fre
