ISO 17076-1:2020

Overview

ISO 17076-1:2020, titled Leather - Determination of abrasion resistance - Part 1: Taber® method, is an international standard developed by ISO in collaboration with IULTCS and CEN. This document specifies a precise method to measure the abrasion resistance of leather using a Taber® apparatus. It outlines a standardized testing procedure vital for ensuring leather quality and durability in various industries.

The standard provides comprehensive guidance on sample preparation, testing apparatus, abrasion testing procedure, and reporting results. It helps manufacturers, testers, and researchers evaluate leather's resistance to wear caused by rubbing or friction, which is crucial for maintaining product longevity and consumer satisfaction.

Key Topics

• Scope and Purpose
  Defines a standardized test to assess abrasion resistance using a Taber® apparatus, providing reliable and reproducible results.

• Test Principle
  The leather sample rotates against two abrasive wheels under specified forces-one wheel rubbing from the center outward, the other inward-simulating wear and observing the resulting damage.

• Apparatus Requirements

  • Motor-driven rotating platform (60 ± 5 rpm) with a circular test piece holder
  • Two pivoted arms holding abrasive wheels (tungsten carbide, rubber-based, or silicon carbide) pressed with controlled loads
  • Vacuum nozzle to remove debris during testing
  • Additional weights for variable loading conditions
  • Equipment for abrasive wheel conditioning and preparation
  • Magnifiers and grey scale for detailed damage and color change assessment

• Sample Preparation

  • Circular leather test pieces (diameter 106 ± 1 mm) mounted on rigid backing sheets
  • Conditioning according to ISO 2419 for standardized atmospheric conditions prior to testing

• Testing Procedure

  • Preparation and reconditioning of abrasive wheels to ensure consistent abrasion
  • Execution of abrasion cycles with set loads (2.5 N to 9.8 N) while recording damage and color changes
  • Visual evaluation supported by magnification and grey scale assessment

• Test Reporting
  Reports must include reference to ISO 17076-1:2020, number of cycles, type of abrasive wheel and loading, observations of damage or color change, testing atmosphere, and any procedural deviations.

Applications

The standard is widely applicable across industries where leather products face mechanical wear, including:

• Footwear Manufacturing
  Ensuring shoes meet durability standards for abrasion resistance, improving customer satisfaction and product lifespan.

• Leather Goods and Accessories
  Testing for handbags, belts, and furniture upholstery to predict wear performance under regular use.

• Automotive and Aviation Interiors
  Assessing leather upholstery resistance to abrasions caused by frequent contact, contributing to quality control and safety.

• Quality Control Laboratories
  Standardized abrasion testing for rawhide and finished leather, enabling supplier evaluation and compliance monitoring.

• Research and Development
  Developing new leather finishes or treatments aimed at enhancing abrasion resistance using consistent, repeatable testing methods.

Related Standards

• ISO 2418 – Leather sampling locations ensuring representative test samples
• ISO 2419 – Leather physical and mechanical testing, covering sample preparation and conditioning
• ISO 105-A02 – Grey scale for assessing color change, used in evaluating leather discoloration after abrasion
• ISO 6103 – Static testing and permissible unbalances for grinding wheels, relevant for abrasive wheel maintenance

Practical Value

Implementing ISO 17076-1:2020 ensures that:

• Leather abrasion resistance is tested under controlled, internationally recognized conditions, improving consistency and comparability of results
• Manufacturers can optimize leather treatment processes to enhance durability and meet market requirements
• Testers benefit from clear procedural guidance and standardized equipment specifications, reducing variability
• Product quality assurance is supported by accurate documentation of abrasion resistance performance
• Buyers and clients gain confidence in the durability claims of leather products based on rigorous testing protocols

By incorporating ISO 17076-1:2020 into quality control processes, organizations improve product reliability, reduce customer complaints related to wear, and align with global leather industry standards.
