20、(E) 3 “1 ScopeThis International Standard specifies a method of determining the dimensional change (shrinkage) of leathers caused by ageing. It is applicable to all leathers.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indisp
21、ensable 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-B06, Textiles Tests for colour fastness Part B06: Colour fastness and ageing to artificial light at high

23、rincipleA conditioned test piece is aged using the conditions defined in ISO 17228. The shrinkage is determined after reconditioning.4 Apparatus and materials4.1 Oven, as specified in ISO 17228.4.2 Climate chamber, as specified in ISO 17228.4.3 Vernier calliper, reading to 0,1 mm.4.4 Support, glass
24、plate covered with a polyester nonwoven fabric (as specified in ISO 105-B06).NOTE The glass plate support keeps the test piece flat and the polyester fabric stops the test piece from sticking to the glass.4.5 Press knife, square, as specified in ISO 2419 with inner walls measuring 150 mm 1 mm.4.6 In
25、delible marker.5 Sampling and sample preparation5.1 Sample in accordance with ISO 2418. Cut at least two test pieces (150 150) mm for each of the ageing conditions required, by applying the press knife (4.5) to the grain surface, if distinguishable.DIN EN ISO 17130:2013-08 EN ISO 17130:2013 (E) 4 NO
26、TE For some applications, it can be necessary to use larger test pieces e.g. (300 300) mm to enhance the accuracy, especially in the case of low shrinkage.5.2 Using an indelible marker (4.6), mark the lines and measurement reference points A, B, C and D on the test pieces. Mark a square with a lengt
27、h of (100 1) mm (Figure 1).Dimensions in millimetres 1 mmFigure 1 Location of lines and measurement reference points on a test pieceIf test pieces with another dimension, e.g. (300 300) mm, are used, a square should be marked with a distance to each edge of (25 1) mm.5.3 Condition the test pieces in
28、 accordance with ISO 2419 for at least 48 h.6 Procedure6.1 Measure the distances AB, CD, AC and BD on each test piece using the vernier calliper (4.3).6.2 Preheat the oven (4.1) to the test temperature or adjust the climate chamber (4.2) to the starting conditions. Place the test pieces with the gra
29、in side, top side or coated side downward on the support (4.4) in the centre of the oven or climate chamber.To allow a fast exchange of humidity, it is necessary to place the leather in such a way that an intensive contact of the air in the oven or climate chamber with the flesh side of the leather
30、is guaranteed.6.3 Age the test pieces as described in ISO 17228.6.4 If required, measure the distances between the measurement points following the description in 6.1 immediately after ageing (not later than 5 min). In this case, report that the measurement was made immediately.DIN EN ISO 17130:2013
31、-08 EN ISO 17130:2013 (E) 5 6.5 Recondition the test pieces for at least 48 h in accordance with ISO 2419.6.6 Measure the distances between the measurement points following the description in 6.1.6.7 Note any visual changes of the test piece, such as distortion and any changes in flexibility and sof
32、tness manually.7 Expression of results7.1 The shrinkage may be expressed as linear shrinkage (see 7.2) or loss of area (area shrinkage)(see 7.3).7.2 The linear shrinkage is calculated using Formulae (1), (2) and (3).Calculate the mean of original length, L1, bounded by the points ABCD on the test pi
33、ece, as follows:Lacbd111114=+ () (1)where a1, b1, c1, and d1are the values of the dimensions AB, BD, CD, AC respectively (see Figure 1), measured before the test.Calculate the mean of length after the test, L2, bounded by the points ABCD on the test piece, as follows:Lacbd222224=+ () (2)where a2, b2
34、, c2and d2are the values of the dimensions AB, BD, CD, AC respectively (see Figure 1), measured after the test.Calculate the percentage linear shrinkage SLusing the Formula (3):SLLLL=121100 (3)whereL1is the mean of original length, calculated from Formula (1);L2is the mean of length after the test,
35、calculated from Formula (2).7.3 For the calculation of loss of area (area shrinkage) SAproceed as follows:Calculate the original area, A1, bounded by the points ABCD on the test piece, as follows:Aacbd1111122=+(4)where a1, b1, c1and d1are the values of the dimensions AB, BD, CD, AC respectively (see
