DIN EN ISO 20869:2010-10 EN ISO 20869:2010 (E) 1 Scope This International Standard specifies a method for the determination of the water soluble contents for outsoles, insoles, lining and insocks. 2 Normative references The following referen

19、ced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 17709, Footwear Sampling location, preparation and duration of con

20、ditioning of samples and test pieces ISO 18454, Footwear Standard atmospheres for conditioning and testing of footwear and components for footwear 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 water soluble matter quantity of all those subs

21、tances that, under certain conditions, are dissolved out of the material by water 3.2 water soluble inorganic substances sulfated ash of water soluble substances 3.3 water soluble organic substances difference between total water solubles and sulfated ash of water solubles 4 Apparatus The following

22、apparatus and material shall be used: 4.1 650 ml to 750 ml flask, with a wide neck and close-fitting glass or rubber stopper. 4.2 Fluted filter, 185 mm in diameter. 4.3 500 ml measuring vessel. DIN EN ISO 20869:2010-10 EN ISO 20869:2010 (E) 44.4 50 ml delivery pipette. 4.5 Quartz, platinum or porcel

23、ain evaporating basin, with flat bottom, to hold 50 ml, and suitable desiccators. 4.6 Funnel and 300 ml Erlenmeyer flask. 4.7 Appropriate shaker apparatus, capable of (50 10) rpm (0,867 0,167)s. 4.8 Thermometer. 4.9 Laboratory balance, with a sensitivity of 0,1 mg. 4.10 Analytical balance. 4.11 Suit

24、able oven, set to (102 2) C. 4.12 Water bath. 4.13 Muffle oven, set to (690 10) C. 5 Reagents 5.1 Distilled water. 5.2 1 mol/l sulfuric acid. 6 Sampling Test specimens shall be taken in accordance with ISO 17709. The material shall be ground and extracted with dichloromethane using a soxhlet apparat

25、us for a minimum of 30 refluxes of solvent. Condition the material for 24 h in accordance with ISO 18454. A minimum of two test pieces is necessary. 7 Test method 7.1 Shaking in water Shake mechanically at (50 10) rpm for 2 h, 10 g of conditioned ground and dichloromethane extracted material with 50

26、0 ml distilled water at (23 2) C in a wide-necked flask (4.1). 7.2 Filtrate Filter the contents of the flask through a fluted filter until clear. Discard the first 50 ml of the filtrate. Determine the soluble organic and inorganic substances in a further 50 ml of the subsequent filtrate. 7.3 Total w

27、ater solubles Evaporate on the water bath (4.12) until dry, exactly 50 ml of the filtrate in a previously weighed dish heated at (690 10) C, drying at (102 2) C for approximately 2 h; cool in the desiccator; and weigh quickly. Only one dish at a time shall be put into a small desiccator and at most

28、two into a large desiccator. Repeat drying until the reduction in mass amounts to less than 2 mg, but not for more than 8 h. DIN EN ISO 20869:2010-10 EN ISO 20869:2010 (E) 57.4 Sulfated ash of water solubles Thoroughly wet the residue obtained in accordance with 7.3 in the dish with a few drops of 1

29、 mol/l sulfuric acid (5.2), fume over a low flame until no sulfuric acid vapour is visible. Heat until red hot. Transfer to the muffle oven (4.13) at (690 10) C for 15 min. Cool in the desiccator and weigh as quickly as possible. Repeat the addition of acid, heating, cooling and weighing until the m

30、ass of the residue is constant. NOTE If the mass of water soluble inorganic matter is likely to be less than 2,0 %, a 100 ml or 200 ml aliquot portion should be used. 8 Expression of results 8.1 The total water solubles, mws, in per cent, is given by Equation (1) dwsc10 100rmm= (1) where rdis the ma

31、ss of dry residue, in grams; mcis the original mass of the component, in grams. 8.2 Sulfated ash of water solubles, msaws, in per cent, is given by Equation (2) sisawsc10 100rmm= (2) where rsiis the mass of sulfated residue from ignition, in grams. 8.3 Water soluble organic substances are the differ

32、ence between the total water soluble substances and the water soluble inorganic substances. The result is the average of the two values obtained for each test piece. All values are calculated on the basis of fat free conditional samples. 9 Test report The test report shall include, at least, the fol

33、lowing information: a) a reference to this International Standard, i.e. ISO 20869:2010; b) results, expressed in accordance with Clause 8, rounded up or down to one decimal place; c) full identification of the sample; d) reference to this method of test; e) date of testing.
