38、paration5.1 Sample in accordance with ISO 2418. From the sample, cut three test pieces by applying the press knife (4.3) to the grain surface. Condition the test pieces in accordance with ISO 2419.If there is a requirement for more than two hides or skins to be tested in one batch, then only one sam
39、ple need be taken from each hide or skin, provided that the overall total is not less than three test pieces.5.2 Weigh the test piece to the nearest 0,001 g or determine its volume in accordance with ISO 2420.5.3 Carry out all further operations at a temperature of 20 C 2 C or 23 C 2 C. There is no
40、further need for humidity control.6 Procedure6.1 Ensure that the Kubelka apparatus (4.1) is clean and free of grease. Wet the interior surfaces with distilled or de-ionized water (4.5) and pour out the excess.6.2 Place the apparatus with the bulb (A) directly below the cylinder (B) and fill with suf
41、ficient distilled or de- ionized water (4.5) at 20 C 2 C or 23 C 2 C to give a water level between 0 ml and 1 ml on the graduated scale. Record the scale reading.6.3 Place the test piece in the cylinder (B) and pour the water from the bulb (A) into the cylinder. Close the cylinder with the stopper (
42、C) to prevent evaporation losses and place the apparatus on a level surface.6.4 After the test piece has been immersed for a specific time (see Note 1 to 6.5) turn the apparatus so that the water drains into the bulb. One min after drainage, note the scale reading at the water level and calculate th
43、e volume of water absorbed.6.5 If the water absorption is required at other time intervals, turn the apparatus immediately so that the water flows back into the cylinder (B) and again covers the test piece. Repeat the operation in 6.4.NOTE 1 For most purposes, measurements after two periods of immer
44、sion are sufficient. If possible, the periods are taken from the following, 15 min 0,2 min; 30 min 0,2 min; 60 min 0,5 min; 120 min 0,5 min; 24 h 0,1 h.NOTE 2 The periods of 1 min during which the water is being drained back are not to be considered as part of periods of immersion which precede them
45、, but are considered as parts of subsequent periods of immersion. For example, if the water absorptions during periods of immersion of 15 min and 60 min are to be measured on the same test piece, and the instant of first immersion is at time zero, subsequent actions will be as follows: at 15 min, be
46、gin draining, at 16 min, read off the residual volume and immediately re-immerse the test piece, at 60 min, begin draining, at 61 min, read off the residual volume.EN ISO 2417:2016 (E) 6DIN EN ISO 2417:2016-07 7 Expression of resultsCalculate the water absorption, Q, (%V/m) in millilitres per 100 g,

48、mass of the test piece in grams as determined in 5.2.NOTE ISO 2420 determines the volume in cubic millimetres. Thus it is divided by 1 000 to give the correct value of V2in millilitres.8 Test reportThe test report shall include the following:a) a reference to this International Standard, i.e. ISO 24
49、17;b) the mean water absorption (in millilitres per 100 g, Q, or in millilitres per 100 ml, P) for each period of immersion;c) the standard atmosphere used for conditioning and testing as given in ISO 2419;d) any deviations from the method specified in this International Standard;e) full details for identification of the sample and any deviation from ISO 2418 with respect to sampling.EN ISO 2417:2016 (E) 7DIN EN ISO 2417:2016-07
