1 Scope
This European Standard specifies a method for the determination of the composition of feather and/or
down fit for or constituting filled manufactured articles in order to label and/or mark it or 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. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
EN 1883, Feather and down - Sampling in view of tests
EN 1885, Feather and down - Terms and definitions
EN ISO 139, Textiles - Standard atmospheres for conditioning and testing (ISO 139)
3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1885 apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
4 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 and
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;
— 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 during the execution of the test, made of glass or other transparent
material to permit the separation of the elements;
— lamp to allow the illumination of the box.

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 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 Conditioning of the samples is carried out according to EN ISO 139.
