DOWN AND FEATHER DEFINITIONS

The definitions of down and feather components differ from country to country. The following are two of the most widely accepted definitions:

The International Down and Feather Bureau (IDFB) establishes testing methods and other standards for the international community. All national and regional down and feather associations belong to IDFB. Most countries use the IDFB standards as the base for their own standards. In the case where IDFB does not have a definition, we have used the USA/ABFLO definition. (ABFLO is the International Association of Bedding and Furniture Law Officials.)

The European EN 1885 is the most recent effort by the European Union to standardize definitions for all countries of Europe:

After Shaft

 

(2.10 After Shaft) Feather (2.3.1) that branches off from the same quill point (2.9) of a normal feather and that is smaller than this one; it is typical of chickens and turkeys.

Barb, Down

Soft filamentous structure emanating from the quill point of the down.

(2.20 Down barb and plumule barb) Filamentary structure furnished with barbules (2.21) with nodes (2.25), but generally without prongs (2.22), thorns (2.23) and clamp teeth (2.24). The down barb emanates directly from the down core (2.13), while the plumule barb emanates from the quill shaft (2.8) of the plumule.

Barb, Feather

A primary branch emanating from the quill shaft of feathers, plus its barbules, being coarse in structure and appearance when compared with down barbs.

(2.19 Feather Barb) Main structure of the vane (2.11), directly growing from the quill shaft (2.8) and bearing barbules (2.21), with prongs (2.22), thorns (2.23) and clamp teeth (2.24). It has normally no nodes (2.25).
