Overview
SIST EN 17900:2023 Leather - Standard Data for the Calculation of Leather Density is a European Standard published by CEN that specifies average density values for different types of leather based on animal origin and the thickness of the finished leather. This standard is designed primarily to support Life Cycle Assessment (LCA) in the leather supply chain, providing a sound basis for calculating environmental footprints, such as the carbon footprint, for bovine, ovine, and caprine leathers. SIST EN 17900:2023 does not apply to vegetable-tanned sole leather, which is typically traded by weight rather than surface area.
Key Topics
- Leather Density Determination: The standard establishes default density values for finished leather (grain), considering animal type (bovine, caprine, ovine) and specific thickness ranges.
- LCA Support: By providing standardized density data, SIST EN 17900:2023 facilitates the conversion of leather surface area (m²) into weight (kg), a crucial step for accurate environmental impact calculations.
- Scope of Application:
- Bovine leather (commonly used for upholstery, footwear, automotive interiors)
- Caprine leather (goat - favored for gloves and luxury goods)
- Ovine leather (sheep - often used in fashion apparel)
- Exclusions: Vegetable sole leather, which is traded and assessed by weight, is outside the scope of this document.
Applications
SIST EN 17900:2023 serves several key practical purposes in the leather industry:
Environmental Footprint Analysis: Ensures consistency and reliability in Life Cycle Assessment (LCA) studies by providing reference values for leather density, which are essential when calculating the carbon footprint of leather products and for eco-design.
Supply Chain Data Standardization: Enables tanneries, manufacturers, and downstream users to use the same default data in their sustainability reporting and internal product calculations, reducing variability and enhancing comparability between companies and products.
Product Development and Eco-Design: Assists manufacturers in estimating material inputs based on leather origin and thickness, improving design for recycling, minimization of environmental impact, and compliance with European environmental labeling requirements.
Regulatory Compliance and Communication: Supports accurate disclosure of product composition and environmental impact in line with European policies and regulations, especially for those exporting or selling in the EU market.
