Foreword

I S 0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

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 YO of the member bodies casting a vote.

International Standard IS0 105-E13 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coioufed textiles and colorants.

This third edition cancels and replaces the second edition (IS0 105-E13:1987), of which it constitutes a technical revision.

IS0 105 was previously published in thirteen “parts”, each designated by a letter (e.g. ”Part A”), with publication dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the re- spective part letter and by a twodigit serial number (e.g. “Section AO1 ”). These sections are now being republished as separate documents, them- selves designated “parts” but retaining their earlier alphanumeric desig- nations. A complete list of these parts is given in IS0 1 05-AO1.

Descriptors: textiles, dyes, tests, chemical tests, acid resistance tests, determination, colour fastness.

IS0 1 05-F: 1 985, Textiles - Tests for colour fastness - Part F: Standard adjacent fabrics.

3 Principle

A specimen of the textile in contact with adjacent fabrics is milled in solutions of acetic acid and/or sulfuric acid, rinsed and dried. The change in colour

of the specimen and the staining of the adjacent fab- rics are assessed by comparison with the grey scales.

4 Apparatus and reagents

4.1 Suitable open container and glass rod, flat- tened at one end, or appropriate mechanical device (see 6.2).

4.2 Sulfuric acid, aqueous solution containing 1 ml of concentrated sulfuric acid (g 1.84 gfml) per litre.

4.3 Acetic acid, aqueous solution containing 5 ml of acetic acid (300 glrnl) per litre.

4.4 Two adjacent fabrics, in accordance with the appropriate section Fol to F08 of IS0 105-F:1985, each measuring 40 mm x 100 mm, one piece made of woof and the other made of wool or of another fi- bre, as desired, to be assessed for staining.

4.5 Grey scale for assessing change in colour, complying with IS0 105A02, and grey scale for as- sessing staining, complying with I S 0 105-A03.

5 Test specimen

5.1 If the textile to be tested is fabric, attach a specimen measuring 40 mm x 100 mm between the two adjacent fabrics (4.41, also measuring 40 mm x 100 mm, by sewing along one of the shorter sides.

5.2 If the textile to be tested is yarn, knit it into fabric and treat it as in 5.1, or form a layer of parallel lengths of it between the two adjacent fabrics (4.41,

the amount of yarn taken being approximately equal to half the combined mass of the adjacent fabrics. Sew along all four sides to hold the yarn in place and to form a composite specimen.

5.3 If the textile to be tested is loose fibre, comb and compress an amount approximately equal to half the combined mass of the adjacent fabrics (4.4) into a sheet 40 mm x 100 mm. Place the sheet between the two adjacent fabrics and sew along all four sides to hold the fibres in place and to form a composite specimen.

6 Procedure

6.1 Test the composite specimen in accordance with 6.2 to 6.4 inclusive, using sulfuric acid solution (4.2) and acetic acid solution (4.3) in separate tests, or using only one of these reagents, as required. The liquor ratio in both cases shall be 40:l.

6.2 If possible, use a mechanical milling device set to give results identical with those obtained in a manual milling test.

NOTE 1 test provided that equivalent results are obtained.

Other meCh8niCd devices may be used for the

6.3 Bring the test solution to 90 O C & 2 "C in the container, and immerse the composite specimen in the solution for 30 min, maintaining this temperature.

6.4 When milling by hand, move the composite specimen about continuously with the glass rod while it is in the rnilling-bath, and press it with the rOd every 2 min, without removing it from the bath.

6.5 Rinse the milled composite specimen for 10 min in cold, running tapwater and drain it. Open out the composite specimen (by breaking the stitch- ing on all sides except one of the shorter sides if necessary) and dry it by hanging it in air at a tem- perature not exceeding 60 O C , with the parts in con- tact only at the iine of stitching.

6.6 Assess the change in colour of the specimen and the staining of the adjacent fabrics by comparison with the grey scales (4.51.

7 Test report

The test report shall include the following information:

the number and year of publication of this part of IS0 105, ;.e. IS0 105-E13:1994;

all details necessary for the identification of the sample tested;

for each reagent used, the numerical grey scale rating for change in colour of the test specimen;

for each reagent used, the numerical grey scale rating for staining of the adjacent fabrics, and the type of adjacent fabric used.
