Overview

The prEN ISO 20867 standard, titled Footwear - Test methods for insoles - Heel pin holding strength (ISO/DIS 20867:2016), is a crucial international standard developed by CEN. It specifies a reliable and consistent test method to evaluate the heel pin holding strength of insoles used in footwear construction. The standard focuses on determining the ability of insole components to securely hold heel pins and prevent the pin head from being pulled through the insole material.

This method applies broadly to insoles positioned in footwear seats with inside attached heels, as well as seat components where outside heel attachments utilize clenched heel pins. The standard aims to ensure durability, performance, and user safety related to heel fastening in footwear manufacturing.

Key Topics

  • Heel Pin Holding Strength
    Defines the force required to push a simulated heel pin head through the insole material, reflecting the insole’s ability to retain heel attachment pins effectively.

  • Test Apparatus & Materials

    • Drill with 2.0 mm ± 0.1 mm diameter bit for creating test holes
    • Tensile-testing machine (dynamometer) compliant with ISO 5893 standards, capable of a constant traverse speed of 100 mm/min ± 20 mm/min
    • Special attachments for force application, simulating a heel pin with precise dimensions for realistic testing
    • Dial micrometer gauge to measure test piece thickness accurately
    • Conditioning materials such as distilled water for wet testing scenarios
  • Sampling and Conditioning
    Procedures specify how to cut test pieces from footwear insoles to sizes of 80 mm x 20 mm, with conditioning for dry and wet testing. Dry test samples are conditioned under standard atmospheres for at least 48 hours prior to testing, whereas wet tests involve soaking specimens in water at 23 ºC ± 2 ºC for 6 hours.

  • Test Procedures

    • Dry test: measuring thickness, drilling holes, inserting test rod simulating heel pin, and gradually applying force until failure occurs.
    • Wet test: similar procedure as the dry test but performed immediately after water soaking to ensure material behavior under moist conditions.
  • Results Expression and Test Reporting
    The standard requires the calculation and reporting of mean maximum forces from test repetitions, expressed in Newtons, representing the heel pin holding strength for both wet and dry samples. Detailed test reports must include sample identification, sampling methods, deviations if any, testing dates, and environmental conditions.

Applications

This standard is essential in the footwear industry, particularly for manufacturers and quality control professionals involved in:

  • Designing and producing insoles with strong heel pin attachment features to enhance durability and wear comfort.
  • Evaluating insoles for shoes featuring inside-attached or outside-attached heels to ensure reliable heel fixing.
  • Quality assurance laboratories to verify compliance of footwear components with international performance standards.
  • R&D departments aiming to innovate or improve materials and attachment methods to withstand forces that could lead to heel detachment.
  • Certification bodies assessing the safety and longevity of footwear products before market approval.

Implementing this standard ensures footwear products meet customer expectations for heel stability, are safe during wear, and maintain product integrity over time. This reduces returns and increases satisfaction.

Related Standards

  • ISO 18454: Footwear - Standard atmospheres for conditioning and testing
    Provides guidelines on atmospheric conditions for reproducible footwear testing.

  • ISO 17709: Footwear - Sampling location of components
    Details proper sampling methods for consistent representation of footwear components during tests.

  • ISO 5893: Rubber and plastic test equipment
    Specifies requirements for tensile testing equipment used in quality evaluation, ensuring accurate force measurements.

These standards complement prEN ISO 20867 by ensuring environmental control, representative sampling, and precise measurement in footwear component testing.
