Overview
ISO 2419:2024, titled Leather - Physical and mechanical tests - Specimen and test piece conditioning, is an international standard developed by ISO in collaboration with the International Union of Leather Technologists and Chemists Societies (IULTCS) and the European Committee for Standardization (CEN). This fifth edition supersedes the previous 2012 version and standardizes the conditioning process for leather specimens and test pieces prior to physical and mechanical testing. The standard applies to all types of dry leather and aims to ensure consistent, reliable test results by specifying controlled atmospheric conditions during specimen preparation and testing.
Key Topics
Specimen and Test Piece Definitions
- Specimen: A portion of leather from which test pieces are cut.
- Test piece: A precisely cut sample from a specimen designed for testing.
Standard Atmospheres for Conditioning
- Reference standard atmosphere: 23.0 °C, 50% relative humidity (RH).
- Alternative standard atmospheres, used upon agreement:
- Specific: 20.0 °C, 65% RH.
- Tropical: 27.0 °C, 65% RH.
- Permissible tolerance: ±2.0 °C temperature, ±5.0 % RH.
Conditioning Procedure
- Leather specimens/test pieces must be conditioned for a minimum of 24 hours in an atmosphere that meets these standards.
- Specimens must be supported to allow free air circulation on all surfaces, with air kept in motion.
- High moisture-content leather should be dried prior to conditioning to meet dry leather criteria.
Testing Environment
- Tests should be conducted in the same standard atmosphere in which the specimen was conditioned, when specified by the test method.
Reporting Requirements
- Test reports must reference ISO 2419:2024 and include details on conditioning climate conditions, any alternative atmospheres used, deviations from standard procedures, and test dates.
Applications
ISO 2419:2024 is crucial for manufacturers, testing laboratories, and quality assurance professionals involved in the leather industry. Proper conditioning of leather specimens directly influences the reproducibility and comparability of physical and mechanical test results such as tensile strength, elongation, and flexibility. Key applications include:
- Quality control during leather production and processing.
- Research and development assessing leather material properties.
- Compliance with client and regulatory testing requirements.
- Supporting international trade by providing standardized test protocols recognized worldwide.
By following ISO 2419:2024, stakeholders can minimize variability caused by environmental factors, ensuring test outcomes accurately reflect the material’s properties under controlled conditions.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
