ASTM D1912-00(2023) PDF

Overview

ASTM D1912-00(2023) - Standard Test Method for Cold-Crack Resistance of Upholstery Leather is an internationally recognized method developed by ASTM to assess how well upholstery leather withstands cracking when exposed to low temperatures. This test is especially valued in the automotive industry, where leather interiors must resist cold-induced damage. The standard offers a reproducible way to compare the cold-crack resistance of different leather types, excluding wet blue leather.

Key Topics

• Cold-Crack Resistance: This method evaluates the durability of upholstery leather under cold conditions by mechanically stressing a pre-conditioned leather specimen.
• Applicability: Relevant for all types of upholstery leather with particular significance in automotive applications.
• Test Conditions: The method uses specific machinery and environmental controls, such as the Greuel Rotary Cold-Fold Test Machine and a cold cabinet capable of maintaining temperatures from −50°F to +20°F (−45°C to −6°C).
• Test Procedure: Specimens are conditioned in a controlled humidity and temperature environment, then exposed to mechanical flexing in the cold. Cracks in the leather finish or substrate are assessed to determine failure.
• Reporting and Reproducibility: Results are considered reproducible and correlate well with other tests and real-world practice. Details such as the temperature at which failure occurs must be reported.

Applications

The cold-crack resistance test is vital for evaluating leathers used in:

• Automotive Upholstery: Ensuring vehicle interiors maintain durability and appearance even in harsh winter climates. High cold-crack resistance extends the service life of automotive seats and panels.
• Commercial and Residential Furniture: Specifying materials for sofas, chairs, and other furniture expected to perform in cooler environments.
• Quality Assurance and Compliance: Manufacturers and suppliers use this standard to certify products meet required performance specifications for cold environments.
• Research and Development: Assists in the development of innovative leather finish systems, such as urethane, vinyl, and water-based acrylics, that offer improved cold performance.

Related Standards

To comprehensively evaluate leather products for upholstery, consider these related ASTM standards:

• ASTM D3818 – Standard Test Method for Water Resistance of Upholstery Leather
