Footwear - Ageing conditioning

This draft standard specifies laboratory procedures which are intended to imitate the effects of naturally occurring reactions. The physical properties of interest are measured before and after the application of the specified treatments. The effect of the ageing procedures on any of the physical properties of the material may be examined.

Schuhe - Konditionierung für die Alterungsprüfung

Dieser Normentwurf legt Laborarbeitsabläufe fest, mit denen die Einflüsse natürlich auftretender Reaktionen imitiert werden können. Die zu prüfenden physikalischen Eigenschaften werden vor und nach der Anwendung der festgelegten Behandlungen gemessen. Der Einfluß der Alterungsprozesse auf die physikalischen Eigenschaften des Werkstoffs kann geprüft werden.

Chaussures - Conditionnement en vue du vieillissement

La présente norme européenne prescrit des modes opératoires d'essai en laboratoire destinés à imiter les effets induits par des réactions qui se produisent naturellement. Les propriétés physiques considérées sont mesurées avant et après l'application des traitements spécifiés. L'effet des modes de vieillissement sur les propriétés physiques du matériau peut être étudié.

Overview

EN 12749:1999 is a European Standard developed by CEN that defines laboratory procedures for ageing conditioning of footwear materials. This standard outlines methods designed to simulate the natural ageing processes that footwear materials undergo over time. By subjecting materials to controlled ageing treatments, the standard enables the measurement and evaluation of changes in their physical properties. The focus is on replicating real-world conditions to understand how different factors affect the durability and performance of footwear components.

Key Topics

• Ageing Simulation Procedures
  Specifies laboratory methods to imitate natural ageing effects such as exposure to heat, moisture, and other environmental factors that degrade footwear materials.

• Material Testing Pre- and Post-Ageing
  Emphasizes the measurement of physical properties before and after conditioning to assess how ageing impacts strength, flexibility, and appearance.

• Effect on Physical Properties
  Facilitates examination of changes in tensile strength, tear resistance, elongation, and other critical physical characteristics important for footwear quality.

• Standardized Conditioning Environment
  Defines controlled parameters ensuring repeatability and consistency in ageing tests across different laboratories and manufacturers.

Applications

• Footwear Manufacturing Quality Control
  Helps manufacturers evaluate how materials will perform and degrade over time, informing selection of materials that ensure longer product life cycles.

• Materials Research and Development
  Assists researchers in developing improved polymers, leathers, and composites by testing their resistance to ageing factors under standardized conditions.

• Compliance and Certification
  Supports compliance with regulatory and industry requirements by providing recognized test methods for footwear ageing behavior.

• Product Performance Validation
  Enables end-users and brands to validate that footwear meets durability expectations, enhancing customer confidence and brand reputation.
