22、 lot taken to be representative of the whole, and which is available to the laboratory The size and nature of the laboratory bulk sample should be sufficient to overcome adequately the variability of the bulk source and to facilitate ease of handling in the laboratory. 3.7 test specimen manufactured

24、he united packages; these packages are taken at random from a lot. The samples form a laboratmy bulk sample to provide the test specimens required for various tests. 5 Apparatus 5.1 Contaiw, of suitable dimensions in which to mix the laboratory bulk sample. 5.2 Square box, of about (50 X 50) cm in s

25、ize and 15 cm high. 6.3 Wooh cross, for dividing the square box diagonally 6 Procedure 6.1 The representative laboratory bulk sample is conditioned in accordance with EN 20139 and the temperature and relative humidity are measured in accordance with EN 20187. The test specimen for analysis (excludin

26、g determination of moisture content) shall be taken from the conditioned laboratory sample. 6.2 Feather material 6.2.1 If only a single package (bag, bale or manufactured article) is to be tested, three individual samples shall be collected using gloves, at three different places in the contents, i.

27、e. the upper, middle and lower part. The quantity of individual samples taken shall be in accordance with annex A.

28、andom from different items of the lot and at different places. The number of package samples is governed by annex A, as weii as the quantity of material to be extracted from each package. The individual samples together form the laboratory bulk sample. NOTE The packages selected should be intact and

29、 in good exteniai condition. 6.2.3 The laboratory bulk sample is placed in a suitable container (6.1) and carefully mixed. 6.2.4 If the laboratory bulk sample is greater than the one necessary to cany out all the requested analyses, the mixture (6.3) is transferred to the square box (6.2) and equall

30、y spread. The content of the square box is divided with the cross. The content of two opposite triangles is coiiected and equally spread again and the procedure is repeated until there remains the quantity of the laboratory bulk sample necessary for the determination prescribed. 6.3 Manufactured pro

31、duct The quantity of individual samples taken shall be in accordance with Table A2 (first two columns), if not otherwise specified in the standard relevant to the test to be carried out. 7 Rst report The test report sha include at least the following information: - a reference to this stan-, - date

32、and place of sampling; - identification mark of the sample tested; - name and address of the buyer; - name and address of the seller; - the reference to the lot; - the conditions of the lot; - the size of the lot; - the number of drawn unie - the reference to the article on which the elementary draw
