25、ions For the purposes of this standard the following definition applies: oxygen index number (of feather and down) Quantity of oxidizable and soluble material present in the filtrate of the aqueous extract of the material. It provides an index of the cleanliness of the material being tested, and is

26、expressed as milligrams oxygen per 100 g of the individual sample. 4 Principle The aqueous extract obtained at room temperature is titrated with a 0,02 mol/l solution of potassium permanganate. 5 Reagents 5.1 Water Grade 3, in accordance with ISO 3696. 5.2 3 mol/l sulfuric acid. 5.3 0,02 mol/l potas

27、sium permanganate. 6 Apparatus 6.1 Analytical balance, (with sensitivity of 0,1 mg). 6.2 Tumbler jar, capacity 2000 ml. 6.3 Beaker, capacity 2000 ml (in accordance with ISO 3819). 6.4 Beaker, capacity 400 ml (in accordance with ISO 3819). 6.5 Shaking machine, with 150 shakes per min and with shaking

28、 swing of 40 mm or tumbling machine with 150 min 21 . 6.6 Sintered (fritted) filter, pore size index P 160 (equal to G-1) 10 cm diameter (in accordance with ISO 4793). 6.7 One-mark pipette, class A capacity 100 ml (in accordance with ISO 648). 6.8 Graduated pipette, capacity 5 ml (in accordance with

29、 ISO 835-3). 6.9 Microburette, graduated in 0,02 ml (in accordance with ISO 385-3) 6.10 Stopwatch. 7 Conditioning and testing Test specimens of a representative part of the laboratory bulk sample shall be conditioned for a minimum period of 24 h in accordance with EN 20139 and the temperature and re

30、lative humidity shall be measured in accordance with EN 20187. 8 Procedure 8.1 A conditioned test specimen of mass of (10 0,1) g shall be placed in the tumbler jar; after adding 1000 ml of water (5.1), the jar shall be tumbled at room temperature for at least 60 min. 8.2 The resulting suspension sha

31、ll be filtered through the P 160 sintered filter into the 2000 ml beaker (6.3); do not squeeze excess water from the feathers. 8.3 With the pipette transfer 100 ml of the filtrate into a 400 ml beaker, add 3 ml of 3 mol/l sulfuric acid and titrate with 0,02 mol/l potassium permanganate, adding appro

32、ximately 0,02 ml at a time until a pink colour persists for 60 s. 8.4 A bank test of 100 ml water (5.1) shall be mixed with 3 ml of 3 mol/l sulfuric acid and titrated with 0,02 mol/l potassium permanganate, adding approximately 0,02 ml at a time until a pink colour persists for 60 s. 8.5 Repeat the

33、test on another test specimen at least.Page 4 EN 1162 : 1996 BSI 1997 9 Expression of results The oxygen index number is calcuated as follows: l =8 03(A2B ) where: l is the oxygen index number; A is the quantity of 0,02 mol/l potassium permanganate used for the test specimen, in millilitres; B is th

34、e quantity of 0,02 mol/l potassium permanganate used for the blank test, in millilitres. Calculate the mean of the two determinations with the approximation to the nearest integer. 10 Test report The test report shall include at least the following information: the reference to this standard; date a

35、nd place of testing; identification mark of the individual sample tested; the arithmetic mean result to the nearest integer in accordance with clause 9; any departure from the procedure and any other circumstances (for example the presence of antistatic agent) that can have affected the result.
