This document specifies a method for determining the tensile strength, elongation at a specified load and elongation at maximum force of leather. It is applicable to all types of leather.

Abstract

Overview

ISO 3376:2020 specifies standardized methods for testing the physical and mechanical properties of leather, focusing specifically on the . This international standard provides a reliable procedure applicable to all types of leather, ensuring consistent quality assessment for manufacturers, laboratories, and quality control professionals worldwide.

Key Topics

Scope and Applicability
ISO 3376:2020 covers methods for measuring the tensile strength and elongation of leather, applicable to every leather type, from soft flexible leathers to stiff variations.
Test Principle
Specimens are uniformly stretched using a tensile testing machine until reaching a specified force or the point of rupture, while carefully recording force and elongation.
Test Apparatus and Setup
The standard mandates precise equipment specifications, including:
- A tensile testing machine with accurate force measurement (±2%) as per ISO 7500-1
- Specific clamping jaws to prevent specimen slippage (less than 1% relative movement)
- Devices to measure specimen elongation accurately, via jaw displacement or sensors
- Thickness gauges (ISO 2589) and standardized cutting tools for specimen preparation
Specimen Preparation and Sampling
Specimens must be conditioned and cut to precise dimensions, with six samples per leather piece tested in directions both parallel and perpendicular to the backbone. Conditioning follows ISO 2419, and sampling aligns with ISO 2418.
Measurement Procedures
Detailed steps are provided to:
- Measure specimen width and thickness in multiple locations for accuracy
- Apply a preload before tensioning to eliminate slack
- Record maximum tensile force (F_max) and elongation at specified loads
- Calculate tensile strength (MPa) and percentage elongation with formulae based on force, specimen dimensions, and elongation distances
Data Reporting
Test reports must include measured tensile strength, elongation at specified force, elongation at maximum force, specimen details, test conditions, and equipment calibration information.

Applications

The ISO 3376 standard is essential for leather producers, product manufacturers, testing laboratories, and quality assurance teams aiming to:

Validate leather strength for applications in footwear, upholstery, automotive interiors, apparel, and accessories
Assess leather flexibility and stretch properties to ensure comfort, durability, and performance in end-use products
Compare different leather types or tanning methods systematically, supporting material selection and product development
Adhere to international quality benchmarks, enhancing customer confidence and market acceptance
Comply with contractual and regulatory requirements related to leather specifications and certifications

By applying ISO 3376:2020, stakeholders can ensure accurate, reproducible measurements that reflect the true mechanical behavior of leather materials under tensile loading.
