Specie Analysis

What Is It?

The species analysis identifies the species of a feather or a down cluster. Most samples are tested for duck and goose species but other species including landfowl can be identified.

How Is The Test Performed?

After completing the Content Analysis test, 1g of feathers and 0.1g of down clusters are magnified and categorized. The magnification lets the analyst see characteristic nodes that identify the piece as duck, goose, or landfowl.

What Do The Results Mean?

The report lists the percentage by weight of each species identified.

A sample report is listed below:

92% Goose Down
8% Duck Down
87% Goose Feathers
8% Duck Feathers
5% Landfowl

Why Do It?

Governments and buyers require species identification in labeling of down and feather products. The cost of different species of down and feathers can vary greatly. Proper identification and labeling of species help consumers and manufactures buy and sell the correct product.

Content Analysis

What Is It?

Content analysis identifies the components of a down and feather sample.

How Is The Test Performed?

A specific weight of material is hand separated into component categories. 

The test has two parts:

  1. The first separation classifies larger components into the following categories: down with fibers, feathers, broken and damaged feathers, landfowl, and residue.

  2. The second separation classifies smaller components from a sub-specimen of down and fibers category. The categories of the second separation are: down clusters, down fiber, feather fiber, landfowl fiber  and any additional residue  and tiny feathers.

What Do The Results Mean?

The content analysis report gives the percentages by weight of each component category. A sample report:

73.3% Down Cluster
7.2% Down Fiber
4.1% Feather Fiber
11.4% Waterfowl Feathers
1.5% Broken/Damaged Feathers
1.3% Landfowl Feathers / Fibers
1.2% Residue

What Is It?

Governments and buyers require labeling of finished products. The component percentages are the basis of the product label. The various systems for labeling help consumers and manufacturers buy and sell different quality products in a fair and level marketplace.

Color

What Is It?

Color separation tests the amount of white and dark material in a plumage sample.

How Is The Test Performed?

A sample is hand separated into white, dark, and borderline colors. How white a piece is depends on how it compares to a grayscale level. Depending on requirements, the borderline category can be re-classified into white or dark material according to specifications.

What Do The Results Mean?

Percentages of white, dark, and borderline are reported. The percentages are based on weights.

For example, 99% white mean that 99% of the weight of the sample was classified as white.

Why Do It?

Many companies request only white material. Dark material that shows through fabric can dissuade a consumer from purchasing a product. The test gives a quantitative value of how much white material is in the plumage sample.

Standards

IDFL tests down and feathers using the major global standards including EN (Europe), JIS (Japan), IDFB (International), GB (China), VSB (Switzerland), AS (Australia), USA 2000, KS (Korea), CAN (Canada) and CNS (Taiwan).
