15、ord ISO (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 which a techni
16、cal 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 matters of e
17、lectrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to
18、the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for i
19、dentifying any or all such patent rights. ISO 20869 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 309, Footwear, in collaboration with Technical Committee ISO/TC 216, Footwear, in accordance with the Agreement on technical cooperation between ISO and CEN

For da
22、ted references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

24、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 apparatus and material shall be used: 4.1 650 ml to 750 ml flask, with a wid
25、e neck and close-fitting glass or rubber stopper. 4.2 Fluted filter, 185 mm in diameter. 4.3 500 ml measuring vessel.

26、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 Suitable oven, set to (102 2) C. 4.12 Water bath. 4.13 Muffl
27、e 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 apparatus for a minimum of 30 refluxes of solvent. Condition th
28、e 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 500 ml distilled water at (23 2) C in a wide-necked flask
29、(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 water solubles Evaporate on the water bath (4.12) until d
30、ry, 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 two into a large desiccator. Repeat drying until the red
31、uction in mass amounts to less than 2 mg, but not for more than 8 h. BS EN ISO 20869:2010ISO 20869:2010(E) ISO 2010 All rights reserved 37.4 Sulfated ash of water solubles Thoroughly wet the residue obtained in accordance with 7.3 in the dish with a few drops of 1 mol/l sulfuric acid (5.2), fume ove
32、r 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 mass of the residue is constant. NOTE
33、 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 mass of dry residue, in grams; mcis th
34、e 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 difference between the total water soluble
35、 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 following information: a) a reference t
36、o 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.
