17、er and down for use as filling material should meet the requirements of the present standard in order to ensure a high level of hygienic and sanitary conditions in conformity with the provisions of Art. 100 A of the Treaty as asked for by the Consumer Policies Service of the EC Commission. The selec
18、tion of analyses has taken into account the existing information in literature and the requirements of the present European standard have taken into account the use of the finished feather andlor down material or as a filling material of a manufactured article. In this way the industry that processe
19、s feathers and down can verify the degree of efficiency of the processing itself. 1 Scope This European standard provides the requirements necessary to satisfy the hygiene and cleanliness of feather and/or down filling materials. This European standard applies to finished feather and/or down materia
20、ls used as a filling of a manufactured article. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For date

As far as the determination of the microbiologi
23、cal state is concerned, the sampling and packaging of the laboratory bulk sample should be performed to avoid inadvertent contamination and significant alterations to the numbers and nature of micro-organisms in the sample. 4 Requirements regarding the hygiene and cleanliness The mandatory requireme
24、nts for finished feather andlor down material are given in Table 1. For finished milled feather only microbiological state applies. Other optional impurity indicators are mentioned in Table A.1. NOTE down filling material has been thoroughly washed and suitably processed. The bacterial species and r

If the oxygen index number is below
28、or equal to 20 the filling material is considered as hygienically suitable and no further analysis of the microbiological state is necessary. If the oxygen index number is between 20 and 50 the required limits of acceptability of the microbiological state are to be met. If the oxygen index number is
29、 above 50 the filling material is not considered to be hygienically suitable and it has to be reprocessed. In case any of the limits for the microbiological state is exceeded, the filling material cannot be considered hygienically suitable. Marking .! I$ Each bag, bale or other package of feather an
