Overview

ASTM D2213-00(2020) - "Standard Test Method for Compressibility of Leather" - is an internationally recognized standard established by ASTM International. This standard outlines a systematic method for determining the compressibility of sole leather, which is a key factor influencing the material’s wear resistance. Adhering to standardized compressibility testing ensures consistent product quality and reliable comparison between leather samples in both industrial and research settings.

Key Topics

  • Purpose: The test method quantifies the compressibility of finished sole leather, guiding manufacturers in quality assurance and product development.
  • Applicability: Specifically covers finished sole leather, excluding wet blue leather.
  • Measurement Units: Inch-pound units are standard; SI units are included for informational purposes.
  • Testing Principle: Compressibility is measured as the percentage change in thickness when a leather specimen is subjected to a controlled pressure for a set duration.
  • Apparatus: Utilizes a press capable of delivering specified pressure and supporting instrumentation for accurate measurement.
  • Safety and Compliance: Users are responsible for following appropriate safety, health, and environmental practices when applying the standard test.

Applications

The ASTM D2213 standard is valuable across multiple sectors of the leather industry and research, such as:

  • Footwear Manufacturing: Evaluating and optimizing the compressibility of sole leather to enhance wear resistance and product longevity.
  • Quality Control: Ensuring batches of sole leather meet consistent physical characteristics, leading to product reliability and customer satisfaction.
  • Material Comparison: Allowing manufacturers to objectively compare the compressibility of various leather sources and processing techniques.
  • Leather Research and Development: Supporting innovation in tanning, finishing, and composite leather materials by providing a quantifiable metric for material performance.
  • Procurement and Specification: Assisting buyers in specifying and verifying compressibility requirements for supplied leather goods.

Related Standards

Manufacturers, researchers, and quality control professionals using ASTM D2213-00(2020) may also reference the following related standards:

  • ASTM D1610: Practice for Conditioning Leather and Leather Products for Testing - provides consistent environmental conditioning guidelines prior to testing.
  • ASTM D1813: Test Method for Measuring Thickness of Leather Test Specimens - supports precise measurement of leather thickness, an essential part of the compressibility test.
  • Leather Wear Resistance Standards: Several regional and international standards address broader aspects of leather durability, within which compressibility is a crucial parameter.

Summary

By implementing ASTM D2213-00(2020) for testing sole leather compressibility, organizations reinforce compliance with internationally accepted methods and support improved product performance. This directly benefits industries relying on durable leather, particularly in footwear and other high-wear applications, by providing a measurable basis for quality control and material selection.
