EN 1162:1996

Overview

EN 1162:1996 (CEN) specifies a titration-based test method for measuring the oxygen index number of feathers and down. The standard is intended for laboratories and manufacturers involved in feather and down processing, quality control and textile auxiliary materials testing. By defining a repeatable determination procedure, EN 1162:1996 supports consistent evaluation of feather and down materials across production, research and conformity assessment activities.

Key Topics

• Scope and purpose: Clarifies the application to feathers and down and the objective of determining the oxygen index number by titration.
• Method type: Describes a chemical titration method rather than instrumental or physical measurements. The standard focuses on method reproducibility and comparability.
• Quality assurance: Emphasises steps to ensure repeatable results suitable for quality control in manufacturing and laboratory environments.
• Terminology: Defines terms relevant to oxygen index testing in the context of feather and down materials.

Applications

EN 1162:1996 is practical for multiple stakeholders and use cases:

• Manufacturers and processors: Use the method for incoming raw material checks and production monitoring to maintain consistent product characteristics.
• Quality control laboratories: Implement the titration procedure as part of routine testing to verify material properties and support batch traceability.
• Product safety and compliance teams: Employ oxygen index data to inform assessments related to material behaviour and safety considerations in downstream textile applications.
• Research and development: Apply the method to compare treatments, cleaning processes or auxiliary materials that may affect feather and down chemistry.

Benefits of adopting EN 1162:1996 include improved comparability between test results, clearer communication of material properties, and stronger basis for supplier and product specifications.

Related Standards

• Other CEN standards covering feathers, down and related textile auxiliary materials and testing methods. These may address labelling, filling power, cleanliness or hygiene requirements for down-filled products.
• National or regional equivalents that transpose EN 1162:1996 into local standards or guidance documents.

Implementing EN 1162:1996 helps laboratories and manufacturers align on a standardized titration approach for the oxygen index number of feathers and down, supporting reliable quality control and consistent reporting across the textile supply chain.
