1 Scope
This European Standard specifies a method for obtaining a representative laboratory bulk sample of a lot of feather and down and of feather and down in a manufactured product or of a manufactured product.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
EN ISO 139, Textiles – Standard atmospheres for conditioning and testing (ISO 139)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 lot
all containers of a feather material or of manufactured products of one defined type and quality delivered to one customer according to one consignment
3.2 container
units of packaging within the consignment (a carton, a case, a bale, etc.] the identification of which is quoted explicitly on the dispatch note
NOTE Containers can or cannot contain packages.
3.3 package
elementary unit (which can be unwound) within each container in the consignment
3.4 package sample
elementary unit selected at random from those of the lot, regarded as representative of it and from which individual samples are drawn
3.5 individual sample
manufactured article or portion of material drawn in order to prepare a laboratory bulk sample
3.6 laboratory bulk sample
manufactured article or portion of the lot taken to be representative of the whole, and which is available to the laboratory
NOTE The size and nature of the laboratory bulk sample is sufficient to overcome adequately the variability of the bulk source and to facilitate ease of handling in the laboratory.
3.7 test specimen
manufactured article or portion of material required to give an individual test result, and selected from the laboratory bulk sample
3.8 selected at random
taken in such a way that each part of the whole has an equal chance of being selected
6 Procedure
6.1 General
This representative laboratory bulk sample is conditioned according to EN ISO 139. The temperature and relative humidity are also measured according to EN ISO 139. The test specimen for analysis [excluding determination of moisture content) shall be taken from the conditioned laboratory sample.
6.2 Feather material
6.2.1 If only 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.e. the upper, middle, and lower part. The quantity of individual samples taken shall be in accordance with Annex A.
6.2.2 In the case of several packages belonging to one lot, the package sample will be selected at random from different items of the lot and at different places. The number of package samples is governed by Annex A, as well as the quantity of material to be extracted from each package.
The individual samples together form the laboratory bulk sample.
The selected packages should be intact and in good external condition.
