15、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 national standard, either by publication of an identical text or by endorsement, at the latest by October 1998, and conflicting national standards sh

16、all be withdrawn at the latest by October 1998.

These normative references are cited at the appropriate places in the text and the publications are listed

19、 hereafter. For dated references, subsequent amendments or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 1885, Feather and down Terms a

20、nd definitions. prEN 1883, Feather and down Sampling in view of tests. EN 20139, Textiles Standard atmospheres for conditioning and testing (ISO 139:1973). EN 20187, Paper board and pulps Standard atmosphere for conditioning and testing and procedure for monitoring the atmosphere and conditioning of

21、 samples (ISO 187:1990). 3 Definitions For the purposes of this standard, the definitions in EN 1885 apply. 4 Principle A known quantity of the filling material, sampled according to prEN 1883, is separated by hand into its elements: the elements are collected into separate containers which are suit

22、ably marked. The content of each container is weighed in order to determine the mass of the element concerned and therefore to calculate the relative percentages. 5 Apparatus 5.1 Box, for the manual separation constituted normally of: black and smooth base, about 450 mm in length and about 300 mm in

23、 width, having a perforated frame to suitably insert the containers; front part, about 150 mm high open or provided with two openings wide enough to permit the operators hands to enter the box; back part, about 300 mm high; two side parts, fit for front and back parts; cover, to avoid air draughts d

24、uring the execution of test, made of glass or other transparent material to permit the separation of the elements; lamp, allowing to illuminate the box. 5.2 Weighing containers with cover, made of aluminium or other light antistatic material fit to contain and weigh the different elements of the fil

25、ling, capacity up to 300 ml. 5.3 Tweezers, fit to pick the single elements. 5.4 Analytical balance, with an accuracy of 0,1 mg 5.5 Mixing container, whose base dimensions are 300 mm3 300 mm and 150 mm high. 6 Sampling, conditioning and preparation of the test specimens 6.1 Sampling is carried out ac

26、cording to prEN 1883. 6.2 Conditioning is carried out according to EN 20139 and the temperature and relative humidity are measured according to EN 20187. 6.3 Draw from the conditioned laboratory global sample, a sample of not less than 30 g, put it into the mixing container and mix by hand to make i

27、t as homogeneous as possible. From different places of this sample, draw three test specimens, each of them having a mass, weighed with an accuracy of 1 mg, of about 6 g for fillings with a expected down content equal to or less than 30 % and of about 4 g for fillings with an expected down content m

28、ore than 30 %. Each specimen is placed in a separate container. It is necessary to analyse at least two test specimens. If the means of the analysis of the components differ by more than 10 % relative, a third sample shall be analysed. The determinations shall be carried out by skilled operators. 7

29、Procedure 7.1 The separation procedure shall be carried out in a conditioned room in accordance with EN 20139 and the temperature and relative humidity are measured according to EN 20187. 7.2 First separation 7.2.1 Mark the weighing containers (5.2) with the indication A, B, C, D, E and Q; weigh the

30、m with their cover, accuracy 1 mg. Put one of the weighed test specimen (6.3) into the separation box (5.1). With tweezers, remove initially all feathers from the plumage; brush the feathers between thumb and index finger of one hand to remove any down fibre or residual matter caught therein. Identi

31、fy the single elements which are extracted from the test specimen and put them in the suitable weighing containers, as indicated in Table 1.Page 4 EN 12131:1998 BSI 1998 Table 1 First separation of elements and denomination of the corresponding containers Denomnation of containers Elements A Whole w

32、aterfowl feather B Whole landfowl feather C 1 Broken and damaged waterfowl feather C 2 Broken and damaged landfowl feather D Down, plumules, down fibres,feather fibres E Quill feathers Q Residual matter Weigh the contents of the weighing containers, indicating the mass in grams with an accuracy of 0

33、,1 mg. 7.2.2 Calculate the percentage of mass lost during the first separation by the following formula: (1) 100 M 1 -( A+B+C 1 +C 2 +D+E+Q ) M 1 where M 1 is the mass of the test specimen analysed in the first separation and A, B, C 1 , C 2 , D, E, Q represent the mass of the contents of the contai

34、ners. Should the calculation give a loss more than 2 % of M 1 , another test specimen should be analysed. 7.3 Second separation 7.3.1 Place the contents of weighing container D in the mixing container (5.5); mix the contents by hand to make it as homogeneous as possible. Take three test specimens fr

35、om different sections of the mixing container (sub-test specimens): the mass of the sub-test specimens should be at least 0,2 g; weigh it with accuracy 0,1 mg. 7.3.2 Mark the weighing containers (5.2) with the indication F, G, H, I and K; weigh them with their cover, accuracy 0,1 mg. Start the secon

36、d separation from the sub-test specimen with the extraction of the down clusters and plumules using twezeers. Remove from the cluster or from the plumule, the non-entwined down fibres and the entwined feather fibres. Shake each single cluster or plumule five times from an up position to a down posit

37、ion and up again; afterwards slightly flick the elements as you go down and up again. With the tweezers, carefully remove the entwined feather fibres taking care not to remove entwined down fibres. If a down fibre is pulled while removing the feather fibre, the down fibre shall be placed into the co

38、ntainer F, which contains down or plumules. When this operation is completed, place the elements down and plumule in the weighing container F and the other elements, after being identified in the suitable weighing containers, as reported in Table 2. Table 2 Second separation of elements and denomina

39、tion of the corresponding containers Denomination of containers Elements F Down and plumules G Down fibres H Waterfowl feather fibres I Landfowl feather fibres K Residual matter Weigh the contents of the weighing containers reporting the mass in grams with the accuracy of 0,1 mg. 7.3.3 Calculate the

40、 percentage of mass lost during the second separation by the following formula: (2) 100 M 2 -(F + G + H + I + K) M 2 where M 2 is the mass of the sub-test specimen analysed in the second separation and F, G, H, I and K represent the masses of the contents of the containers. If the result of the calc

41、ulation leads to a loss of more than 2 % of M 2 , another test specimen should be analysed.Page 5 EN 12131:1998 BSI 1998 8 Calculation and expression of results 8.1 Calculate the total percentage for each component, after both separations in relation to the total quantity analysed, as follows: 8.1.1

42、 Whole waterfowl feather 100 A M 1 (3) 8.1.2 Whole landfowl feather 100 B M 1 (4) 8.1.3 Broken and damaged waterfowl feather 100 C 1 M 1 (5) 8.1.4 Broken and damaged landfowl feather 100 C 1 M 1 (6) 8.1.5 Quill feathers 100 E M 1 (7) 8.1.6 Down clusters and plumules 100 3 D M 1 F M 2 (8) 8.1.7 Down

44、t specimen, rounded to the nearest integer. 9 Test report The test report shall include at least the following information: the reference to this standard; symbols, marks and other indications used to identify the tested material; the average of the results for each component, expressed as percentag
