EN 12743:1999

Overview

EN 12743:1999 is a European standard developed by CEN that specifies a test method for determining the compression energy of footwear outsoles. This standard focuses on evaluating the energy absorption characteristics of outsoles under compression, an important factor in assessing the comfort, durability, and performance of shoes. By providing consistent testing procedures, EN 12743:1999 helps manufacturers, laboratories, and quality control professionals ensure that footwear meets specific energy absorption requirements.

Key Topics

• Compression Energy Measurement
  The standard outlines a precise method to measure the energy absorbed by outsoles when subjected to compressive forces. This measurement is crucial for understanding how outsoles respond to impacts and pressure during usage.

• Testing Procedure
  EN 12743:1999 defines detailed steps for preparing samples, applying compressive loads, and recording energy absorption data, ensuring repeatability and reliability in testing results.

• Scope of Application
  The standard applies to outrsoles made of various materials used in footwear manufacturing. It does not cover entire shoes but focuses specifically on outsole components.

• Energy Absorption Importance
  Compression energy data helps evaluate outsole cushioning, shock absorption, and potential wear resistance, impacting overall footwear comfort and lifespan.

Applications

• Footwear Manufacturing Quality Control
  Manufacturers use EN 12743:1999 to test outsole materials during production to maintain consistent energy absorption properties, contributing to product quality and customer satisfaction.

• Product Development and R&D
  Research and development teams apply this method to compare different outsole materials, designs, and technologies for enhanced shock absorption and comfort.

• Laboratory Testing and Certification
  Accredited testing laboratories rely on EN 12743:1999 for standardized evaluation of outsoles to support compliance with footwear performance standards.

• Procurement and Supplier Assessment
  Companies use compression energy results to select suitable outsole materials and suppliers that meet their technical requirements.

• Consumer Safety and Comfort
  By ensuring optimal energy absorption in outsoles, this standard indirectly contributes to the safety and ergonomic comfort of footwear users.
