TS EN 1885+A1

TS EN 1885+A1 is a vocabulary standard that brings together the principal terms and definitions used for feather and down. It is intended to support a common technical language in the feather and down field, so that product descriptions, material names, structural features and related process terms are understood consistently across different professional settings.

Why feather and down terminology matters

Feather and down are widely used in insulation and filling applications. In general technical terms, feather refers to the outer plumage with a shaft, while down denotes the softer, lighter clusters with high lofting ability and little or no central quill. That distinction matters because it helps describe bulk, resilience, fill behaviour and intended use. Vocabulary standards do not prescribe test methods; instead, they reduce ambiguity by aligning how the same concepts are named in trade, manufacturing and quality-related communication.

What this standard covers

According to the supplied scope, this document defines the principal terms used in the field of feather and down. It therefore provides a shared terminology framework for source material, forms of plumage, filling use and other core concepts. It is a terminology document, not a product-performance or test-method standard, so it organizes names and definitions rather than specifying how products are made or measured.

• Harmonised terminology and definitions
• Technical distinction between feather and down
• Shared names for materials, products and processes
• Clearer communication in trade, production and quality control
