9、8:2015(E)ForewordISO (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 w
10、hich 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
11、 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. Thi
12、s document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

16、ess of textile floor coverings and yarns, loose fibres and tufts extracted from textile floor coverings, to the action of a reference shampoo solution.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applica
17、tion. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 2424, Textile floor coverings Vocabulary3 Terms and definitionsFor the purposes of this document, the terms and definitions given i
18、n ISO 2424 apply.4 PrincipleA specimen of a textile floor covering, yarn, loose fibre or tuft, in contact with specified adjacent fabrics, is immersed under pressure in a shampoo solution buffered to a pH of (7,5 0,2). The specimen and the adjacent fabric are dried separately. The change in colour o
19、f the specimen and the staining of the adjacent fabrics are assessed using the grey scales.5 Apparatus and reagents5.1 Testing frameThe device consists of a stainless steel frame into which a mass of 5 kg with a base of 60 mm 115 mm fits closely so that a pressure of 12,5 kPa can be applied on test
20、specimens (40 mm 100 mm), placed between glass or acrylic resin plates. If the mass is removed during the test, the testing device shall be constructed so that the pressure of 12,5 kPa remains unchanged.Other devices may be used provided that the same results are obtained as with the apparatus descr

22、poo solutionThis solution is prepared by dissolving 1 g dodecyl sodium sulfate (CAS-number 15-121-3) and 0,2 g lauric mono-isopropanolamide (CAS-number 142-54-1) or 0,2 g coconut diethanolamide (CAS-number 68603-42-9) in 500 ml of deionized or distilled water. If necessary the solution is heated to
23、ensure dissolution of the surfactant. Cool to a temperature of about 30 C.Prepare a buffer solution by adding 14 ml of citric acid 0,5 mol/l (CAS-number 77-92-9) to 372 ml of a disodium hydrogen phosphate 0,5 mol/l (CAS-number 7558-79-4) solution.Add the buffer solution to the surfactant solution an
24、d dilute to 1 l. If required; adjust the pH to (7,5 0,2) using citric acid or sodium hydroxide (CAS-number 1310-73-2), as appropriate.5.4 Adjacent fabrics5.4.1 Textile floor coveringsWhen the test specimen is a textile floor covering, two adjacent fabrics (50 mm 40 mm) shall be used, one made of the
25、 same fibre as in the specimen (or the predominant fibre in the case of blends) and the other one made of the fibre as indicated in the second column of Table 1. If the staining of further fibres is of interest, two or more specimens shall be tested separately.5.4.2 Yarns or loose fibresWhen the tes
26、t specimen is in the form of a yarn or loose fibre, two adjacent fabrics (100 mm 40 mm) shall be used, one made of the same fibre as in the specimen (or the predominant fibre in the case of blends) and the other one made of the fibre as indicated in in the second column of Table 1. If the staining o
27、f further fibres is of interest, two or more specimens shall be tested separately.5.4.3 TuftsWhen the test specimen is in the form of tufts extracted from a textile floor covering, two adjacent fabrics (50 mm 40 mm) shall be used, one made of cotton, to act solely as a support for the tufts, and the
28、 other one made of the same fibre as in the specimen (or the predominant fibre) in the case of blends, or any other fibre. If the staining of two or more fibres is of interest, two or more specimens shall be tested separately.Table 1 Adjacent fabricsFirst piece Second pieceCotton WoolWool CottonSilk

30、 specimens6.1 GeneralA test specimen is prepared in accordance with 6.2 to 6.4. A further original specimen is cut, kept and used as reference for comparison with the tested specimen.6.2 Textile floor coveringCut a specimen 100 mm 40 mm from which any integral foam underlay has been removed, and cov
31、er the use-surface with two pieces of adjacent fabric to form a composite specimen.6.3 YarnsSew a uniform layer of 0,4 g yarn in parallel 100 mm lengths to a side of one of the adjacent fabrics. Cover with the other piece and sew along the same edge to form a composite specimen.6.4 Loose fibres and
32、tuftsComb and compress 0,4 g of the loose fibre or tufts into a uniform layer of 100 mm 40 mm. Place this between the two pieces of adjacent and sew along two opposite sides to form a composite specimen.7 ProcedurePlace the composite specimen in the flat-bottomed dish. In the case of a tuft composit
33、e specimen, the composite specimen should be placed in the dish with the cotton fabric side facing downward on the inside bottom surface.Pour sufficient shampoo solution at a temperature of (37 2) C over the composite specimen to give a liquor-to-goods ratio of at least 10:1 ensuring thorough wettin
34、g of the composite specimen. Cover the composite specimen with a smooth glass or clear acrylic resin plate. Press the plate with the fingers to remove air bubbles and place the 5 kg mass on top of the plate.Allow the dish to stand in an oven at (37 2) C for 15 min. Remove the mass and pour off the s
35、hampoo solution, leaving the plate on the composite specimen intact in the dish.Proceed by eithera) placing an assembly consisting of the composite specimen between two glass or clear acrylic resin plates under a pressure of 12,5 kPa in the testing frame preheated to (37 2) C, and placing the appara
36、tus containing the assembly horizontally in the oven at (37 2) C for 1,5 h, orb) replacing the weight-piece and allow the dish to stand at (37 2) C for a further 1,5 h.Separate the specimen from the adjacent fabrics, hydro-extract them to remove excess liquor and dry them apart in air at a temperatu
37、re not exceeding 60 C.Assess the change in colour of the specimen and the staining of the adjacent fabrics with reference to the original specimen and the original adjacent fabrics, respectively, by comparison with the grey scale. When tufts are tested, the staining of the cotton support shall not b
38、e assessed.Before assessing the test specimen for change in colour, it is recommended that pile lay orientation of the test specimen be restored so that it resembles exactly that of the original specimen.
