17、Foreword This European Standard has been prepared by the Technical Committee CEN/TC 222, Feather and down as filling material for any article, as well as finished articles filled with feather and down, the Secretariat of which is held by UNI. This European Standard shall be given the status of a nat
18、ional standard, either by publication of an identical text or by endorsement, at the latest by February 1997, and conflicting national standards shall be withdrawn at the latest by February 1997. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

The extract is filtered and its chloride ion concentration is determined by a titration technique with standard silver nitrate. To the aqueous extract at ambient temperature is added a small quantity of potassi
27、um chromate as an indicator. 5 Reagents 5.1 Water, grade 2, conforming with ISO 3696. 5.2 Nitric acid, 0,1 mol/l. 5.3 Silver nitrate, 0,01 mol/l, to be stored in a brown bottle. 5.4 Phenolphthalein indicator, solution 1,0% of mass. 5.5 Potassium chromate solution, 3,9 g/l. 5.6 Sodium carbonate solut
28、ion, 10,6 g/l. 6 Apparatus Glassware and other apparatus shall be clean. Boil flasks, beakers and funnels shall be cleaned in distilled water. Forceps and scissors for individual sample preparation shall be kept clean in the same way. 6.1 Analytical balance (with sensitivity of 0,1 mg). 6.2 Tumbler
29、jar, capacity 2000 ml. 6.3 Beaker, capacity 2000 ml (in accordance with ISO 3819). 6.4 Shaking machine, with 150 shakes per minute and with shaking swing of 40 mm or tumbling machine with 150 min -1 . 6.5 One-mark pipette, capacity 25 ml (in accordance with ISO 648). 6.6 Microburette, capacity 10 ml
30、, graduated in 0,01 ml (in accordance with ISO 385-3). 6.7 Sintered (fritted) filter, pore size index P 100 (in accordance with ISO 4793) or chloride-free medium paper filter. 6.8 Glass funnel. 6.9 Conical flasks, capacity 250 ml or 300 ml. 6.10 Latex gloves or equivalent. 6.11 Light source with wav
31、elength of 400600 mm or yellow glasses.Page 4 EN 1165 : 1996 BSI 1997 7 Preparation of the test specimen 7.1 Condition the laboratory bulk sample in accordance with EN 20139 and measure the temperature and relative humidity in accordance with EN 20187. 7.2 Clean protective gloves should be worn at a
32、ll times when handling the individual sample and the test specimens prepared from it. 7.3 Cut the individual sample into pieces approximately 5 mm to 10 mm in size, and mix them thoroughly. Prepare two test specimens at least. 8 Procedure 8.1 For filling containing less than 150 mg/kg of chlorides,
33、use a test specimen of 10 g or more. For filling containing more than 150 mg/kg use a test specimen of such mass that the chloride content concerned is not greater than 1,50 mg. The conditioned test specimens shall be weighed to an accuracy of 10 mg. 8.2 Place the individual sample in a tumbler jar,
34、 add 1 l of water (5.1) and tumble the jar at room temperature for at least 60 min. 8.3 The resulting suspension shall be filtered into the beaker; do not squeeze excess water from down and feather. 8.4 To 200 ml of the filtrate shall be added one drop of phenolphthalein indicator solution (5.4) and
35、 then add 0,1 mol/l nitric acid (5.2) from a measuring pipette until acid, then add sodium carbonate solution (5.6) until alkaline, plus three drops in excess. 8.5 Dropwise add nitric acid (5.2) to just discharge the pink colour. 8.6 Add 0,5 ml potassium chromate solution (5.5) and titrate with 0,01
36、 mol/l silver nitrate (5.3) using a microburette. Add silver nitrate solution (5.3) until a reddish-brown tint is observed under a light source (6.11) or through yellow glasses. 8.7 Determine the amount of silver nitrate solution (5.3) necessary to titrate a blank to the same end point. 8.8 Repeat t
37、he procedure on a second test specimen. 9 Expression of results The chloride content expressed as mass content in mg/kg is calculated as follows: C = 3 1000 AB W where: C is the chloride content, in milligrams per kilogram; A is the volume, in millilitres, of silver nitrate solution (5.3) consumed i
38、n the titration of the test solution, corrected for the blank; B is the chloride equivalent of the silver nitrate solution (5.3); W is the mass in grams of the conditioned test specimen. NOTE. 1 ml 0,01 mol/l AgNO 3 is equivalent to 0,355 mg of chloride. Calculate the mean of the two determinations
39、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 and place of testing; identification mark of the individual sample tested; the arithmetic mean result of the content of water-soluble c
40、hlorides in milligrams per kilogram, and round off the result to the nearest integer; any deviations from the procedure and any other circumstances that can have affected the result.
