ASTM D2099-14(2023) PDF

Overview

ASTM D2099-14(2023), titled Standard Test Method for Dynamic Water Resistance of Shoe Upper Leather by the Maeser Water Penetration Tester, is an internationally recognized standard developed by ASTM International. This test method provides a reliable procedure for measuring the dynamic water resistance of shoe upper leather using the Maeser water penetration tester. The testing simulates the repeated flexing that leather experiences in the vamp of a shoe during actual wear, making it valuable for estimating how well shoe upper leathers resist water ingress under real-world conditions.

The method applies to all types of shoe upper leather except "wet blue" and accommodates both visual and electronic detection methods for water penetration and absorption. This test is especially significant for manufacturers, quality controllers, and researchers focusing on footwear materials and performance.

Key Topics

• Scope of Applicability

  • Applicable to all shoe upper leather types except wet blue
  • Measures both initial water penetration and water absorption
  • Values are provided in inch-pound units as standard

• Testing Methodology

  • Utilizes the Maeser water penetration tester, which flexes the leather specimen in a manner comparable to actual shoe conditions
  • Detects initial water penetration via electronic or visual means
  • Calculates water absorption by comparing the specimen’s mass before and after testing

• Significance and Use

  • Simulates real-life flexing conditions to provide an accurate estimate of dynamic water resistance
  • Enables ranking and selection of leathers based on water resistance for footwear manufacturing
  • Supports research, product development, and quality control by providing actionable data on performance under dynamic conditions

• Safety and Compliance

  • Users must establish appropriate safety, health, and environmental practices relevant to their local regulations
  • Developed in alignment with internationally accepted principles for standardization

Applications

ASTM D2099-14(2023) has broad applications in the leather and footwear industries, contributing to the development, quality assurance, and regulatory compliance of shoe materials. Common applications include:

• Footwear Manufacturing

  • Ensures shoe upper leathers meet water resistance requirements for consumer durability and comfort
  • Supports product claims for water-resistant or waterproof shoes

• Material Selection and R&D

  • Helps in selecting suitable leathers for various footwear designs, especially for outdoor or sports shoes
  • Assists in benchmarking and improving the water resistance of leather via new tanning or finishing processes

• Quality Control

  • Serves as a basis for establishing and maintaining product specifications
  • Provides a pass/fail criterion and allows for comparative ranking of different leather lots or treatments

• Regulatory and Contractual Compliance

  • Aligns with procurement requirements and government agency specifications, including those of the U.S. Department of Defense

Related Standards

Several ASTM standards are referenced and related to the procedures in ASTM D2099-14(2023), including:

• ASTM D1610 - Practice for Conditioning Leather and Leather Products for Testing
• ASTM D2098 - Test Method for Dynamic Water Resistance of Shoe Upper Leather by the Dow Corning Leather Tester
