1 Scope
This document describes the test methods for fine‑washed down and feather and rough‑washed down and feather, and defines the relevant terms.
This document applies to testing of fine‑washed down and feather for the composition analysis, species identification, filling power, cleanliness, oxygen demand, residual fat content, odour, pH and moisture content, as well as the testing of rough‑washed down and feather for the composition analysis, cleanliness and morphological appearance. It is also applies to the testing of fillings in various down and feather products, except where other test methods are specified in relevant standards.
This document does not apply to the testing of blended products of down and feather with other fibres.
