Overview

EN ISO 24264:2020 is a standardized test method developed by ISO and adopted by CEN for assessing the attachment pull-out strength of top pieces on hollow and compact footwear heels. This international standard specifies practical procedures for determining how securely top pieces are fixed to various types of heels, ensuring footwear durability and safety.

It applies universally to all kinds of heels outfitted with top pieces, providing manufacturers, testers, and quality control professionals with a consistent approach to validating heel component strength. By following this method, stakeholders can guarantee performance reliability and improve overall footwear quality.

Key Topics

• Scope
  Specifies a detailed test methodology to determine the pull-out strength of heel top pieces, critical for evaluating heel attachment quality in footwear production.

• Equipment Requirements
  A tensile testing machine with:

  • Jaw separation rate of 100 ± 10 mm/min
  • Force measurement accuracy compliant with ISO 7500-1 Class 2
  • Specialized clamping devices to securely hold the heel and top piece without damage
    Additional tools include drills for hole preparation, knives or cutting tools for sample preparation, and steel cords for force application.

• Sample Conditioning and Preparation
  Samples must be conditioned 24 hours prior to testing at 23 ± 2 °C and 50 ± 5% relative humidity, complying with ISO 18454. The test-piece preparation involves drilling a hole in the top piece and securing it with a steel cord for tensile testing.

• Test Procedure
  The tensile machine applies force until the top piece detaches. The peak force at pull-out is recorded. For top pieces with multiple connection points (pivots), the first maximum force is considered, with repeated tests if tearing occurs.

• Result Expression and Reporting
  Results are expressed in Newtons (N), averaged over at least three specimens. Test reports must include footwear identification, reference to ISO 24264:2020, test date, measured force, and any deviations from the method.

Applications

• Footwear Manufacturing Quality Control
  Ensures heel top pieces are affixed securely, minimizing failures during wear and extending product life.

• Material and Component Testing
  Assesses new heel materials and attachment techniques for durability before mass production.

• Compliance and Certification
  Footwear brands can validate their products against recognized standards, facilitating market approval and customer confidence.

• Research and Development
  Supports innovation in heel design by quantifying the mechanical strength of attachment methods.

Related Standards

• ISO 7500-1 – Calibration and verification of force-measuring systems in testing machines, ensuring measurement accuracy during pull-out tests.
• ISO 18454 – Standard atmospheres for conditioning and testing footwear, critical for reproducible and reliable test outcomes.
• CEN/TC 309 Footwear Standards – European footwear standards under which EN ISO 24264:2020 is adopted, harmonizing footwear testing across EU member states.

---

By adhering to EN ISO 24264:2020, companies involved in footwear design, manufacturing, and testing can ensure the mechanical integrity of heel top pieces, improving user safety and product quality. This standard provides a clear, reliable assessment framework, supporting global consistency and innovation in the footwear industry.
