What is BS EN ISO 23529:2012?

BS EN ISO 23529:2012, also known as the "Footwear - Test methods for outsoles - Determination of abrasion resistance," is an international standard that provides guidelines and procedures for evaluating the abrasion resistance of footwear outsoles.

Importance of Abrasion Resistance

Abrasion resistance is a crucial factor in determining the durability and lifespan of footwear outsoles. A high level of abrasion resistance ensures that the material can withstand repeated frictional forces encountered during everyday use. Without proper abrasion resistance, outsoles may wear out quickly, compromising comfort, grip, and safety.

Footwear manufacturers, retailers, and consumers all benefit from an objective assessment of abrasion resistance provided by BS EN ISO 23529. The standard sets forth reliable testing methods that enable comparison and validation of different outsole materials and designs.

Testing Methods

BS EN ISO 23529 specifies two primary test methods: the Taber test and the Martindale test.

The Taber test involves mounting a rotating cylindrical drum with abrasive wheels onto which the outsole is placed. This drum is then subjected to a specific number of cycles under constant load and speed. After testing, the wear resistance is determined by measuring the weight loss or thickness reduction of the outsole material.

The Martindale test employs a circular fabric sample, known as the abradant, which is rubbed against the outsole surface under a fixed pressure and movement. Similarly, the wear resistance is evaluated by measuring the weight loss or visible damage to the outsole material after a certain number of rubs.

Standard Compliance and Benefits

Footwear manufacturers often rely on BS EN ISO 23529 to assess the performance and quality of different outsole materials. Compliance with this standard ensures that the products meet industry benchmarks and consumer expectations.

From a consumer perspective, understanding the abrasion resistance rating of a shoe can help determine its suitability for specific activities or environments. Footwear designed for sports or outdoor use, for instance, typically requires higher levels of abrasion resistance to withstand rugged terrains and extended wear.

In conclusion, BS EN ISO 23529:2012 plays a vital role in ensuring the durability and performance of footwear outsoles. By providing standardized test methods and evaluating abrasion resistance, this international standard offers valuable insights to manufacturers and consumers alike.
