18、ked. 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 width,

19、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 duri

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 expec

24、ted down content more than Each specimen is placed in a separate container. It is necessary to analyse at least two test specimens.

Should the calculation give a loSS more than 2% of MI, 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 fro

31、m 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,l 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,l mg .

Remove from the cluster or from the plumule the non entwined down fibres and the entwined feather fibres. Shake each single clust

33、er or plumule five times from an up position to a down position 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 th

34、e feather fibre, the down fibre shall be placed into the container 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
