24、to verify the denominations reported on the label. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

27、Principle A known quantity of the filling material, sampled according to EN 1883, is separated by hand into its elements. The elements are collected into separate containers, which are suitably marked. The content of each container is weighed in order to determine the mass of the element concerned a

28、nd therefore to calculate the relative percentages. 5 Apparatus 5.1 Box for the manual separation (separation box), usually consisting of the following parts: black and smooth base about 450 mm in length and about 300 mm in width, having a suitable fixture or area to insert the containers into; fron

29、t 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 during the execution of the test, made of glass or other transparent material

30、 to permit the separation of the elements; lamp to allow the illumination of the box. BS EN 12131:2018EN 12131:2018 (E) 5 5.2 Weighing containers with cover, made of aluminium or other light antistatic material fit to contain and weigh the different elements of the filling, with a capacity up to 300

31、 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 with base dimensions of 300 mm 300 mm and 150 mm high. 6 Sampling, conditioning and preparation of the test specimens 6.1 Sampling is carried out according to EN 1883. 6.2 Co

32、nditioning of the samples is carried out according to EN ISO 139. 6.3 Draw a sample of no less than 30 g from the conditioned laboratory global sample. Put the sample into the mixing container (5.5) and mix carefully by hand to make it as homogeneous as possible. From different places of this sample

33、, draw at least three test specimens, each of them having a mass of about 5 g, weighed with an accuracy of 1 mg, of about 5 g for fillings with an expected down content less than 60 % and of about 3 g for fillings with an expected down content of 60 % or more. Each specimen is placed in a separate c

34、ontainer. NOTE For setting the final result it is necessary to have validated analysis of at least two test specimens while sometimes replacement or additional specimens are to be used. Therefore, a preparation of spares over the three specimens is suggested. 7 Procedure 7.1 General The separation p

35、rocedure shall be carried out in a conditioned room in accordance with EN ISO 139. 7.2 First separation 7.2.1 Mark the weighing containers (5.2) with the indication A, B, C, D, E and Q; weigh them with their cover, with an accuracy of 0,1 mg. Put one of the weighed test specimens (6.3) into the sepa

36、ration box (5.1). With tweezers, remove initially all feathers from the plumage; brush the feathers gently between thumb and index finger of one hand to remove any down fibre or residual matter caught therein. Identify the single elements which are extracted from the test specimen and put them in th

37、e suitable weighing containers, as indicated in Table 1.

39、ing the first separation by the following formula: = 1111100Ew RwVEwmmmm(1) where 1Vm is the mass lost after the first separation in percent (%); 1Ewm is the mass of the test specimen analysed in the first separation (weighed portion); 1Rwm is the masses of the contents of the containers A+B+C1+C2+D

40、+E+Q after being weighed again subsequent to the analysis (control scale). If the calculation gives a loss of mass of more than 2% or a mass gain of more than 0,5 % another test specimen shall be analyzed. To validate the first separation and to continue the process, at least two test specimens shal

41、l meet the criteria of mass loss and mass gain above. For the calculation of the results, see Clause 8. 7.3 Second separation 7.3.1 Place the contents of weighing container D in a clean mixing container (5.5); mix the contents by hand carefully to make it as homogeneous as possible. Take three test

42、specimens, each one is at least 0,1 g. 7.3.2 Mark the weighing containers (5.2) with the indication F, G, H, I,K and L; weigh them with their cover, accuracy 0,1 mg . During the second separation of the sub-test specimen, down, plumules and nestling down are separated from the non-entwined down fibr

43、es and the entwined feather fibres. First, remove a down, plumule or nestling down with tweezers, and slightly shake it five times from an up position to a down position and up again with a short and fast shaking movements of the wrist. BS EN 12131:2018EN 12131:2018 (E) 7 Figure 1 Shaking of down, p

44、lumule or nestling down five times With the tweezers, carefully take off the entwined feather fibres from the down, plumule or nestling down. If a down fibre is pulled while removing the feather fibre, the down fibre shall be placed into the container F, which contains down and plumules. The other e

45、lements are placed, after being identified as reported in Table 2, in the suitable weighing containers. If whole and fractured waterfowl feathers are found in the second separation place them in container L. Table 2 Second separation of elements and denomination of the corresponding containers Denom

48、asses of the contents of the containers F+G+H+I+K after being weighed again subsequent to the analysis (control scale). If the calculation gives a loss of mass of more than 2% or a mass gain of more than 0,5 % another test specimen shall be analyzed. To validate the first separation and to continue

49、the process, at least two test specimens shall meet the criteria of mass loss and mass gain above. 7.4 Milled Feathers Milled feathers consist of chopped and/or curled feathers (see EN 1885). Curled or chopped feathers have multiple fractures along the length of the quill. Milled feathers can be identified from visual examination of the feathers, the broken and the damaged waterfowl and landfowl feathers. 8 Calculation and expression of results 8.1 Calculation of the component portions Calculate the total percentage for each component
