ISO 10748:2011 PDF

Overview

ISO 10748:2011 is an international standard specifying a test method for determining the slider locking strength of slide fasteners used in footwear. This method applies to all types of slide fasteners equipped with a slider locking device, ensuring reliable performance and safety for footwear products. By defining a consistent testing procedure, the standard helps manufacturers assess the durability and locking effectiveness of the fasteners used in shoes, boots, and related products.

Key Topics

• Scope and Applicability The standard covers the test method to evaluate the strength of the slider locking mechanism, which prevents unintended movement of the slider during use or wear. It is relevant to any slide fastener slider equipped with a locking device.

• Terminology Important terms defined include:

  • Slide fastener: The zipper-like component securing two flexible materials.
  • Slider: The device moving along the fastener to interlock or disengage the teeth.
  • Locking device: A mechanism that locks the slider in place.
  • Puller: The manual grip attached to the slider.
  • End stops: Components preventing the slider from disengaging.

• Testing Principle The slider locking device is subjected to a tensile force applied at 180 degrees to the locking mechanism via the fastener chains. The force is increased until the locking device fails or slips.

• Test Setup and Procedure Key equipment and steps include:

  • Use of a tensile testing machine with jaws set approximately 50 mm apart.
  • Application of force at a rate of 100 ± 10 mm/min and measuring up to 2 kN with high accuracy.
  • Conditioning of test specimens at 23 °C and 50% relative humidity for 24 hours prior to testing.
  • Reporting the failure force (slider locking strength) and failure types such as slipping or specimen failure.

• Test Reporting Reports must include:

  • Reference to ISO 10748:2011.
  • Detailed description of the tested slide fastener.
  • Date and conditions of testing.
  • Failure results and average locking strength values.
  • Any deviations from the prescribed method.

Applications

ISO 10748:2011 is essential for footwear manufacturers, quality control laboratories, and product developers who require:

• Quality Assurance Ensuring the slide fasteners used in footwear maintain secure locking to prevent accidental opening and improve user safety.

• Product Development Designing and selecting slide fasteners that meet minimum locking strength requirements for various footwear styles and uses.

• Regulatory Compliance Meeting international standards necessary for market acceptance in regions requiring ISO-conformant footwear components.

• Material and Component Testing Verifying the performance of slider locking devices for durability, contributing to overall footwear robustness and longevity.

Related Standards

• ISO 7500-1 - Metallic materials: Verification and calibration of testing machines used during tensile testing, ensuring force measurement accuracy.

• ISO 19952 - Footwear Vocabulary: Provides terminology used in the footwear industry for clear communication and standardization.

• ISO 17709 - Footwear sampling and conditioning requirements, supporting standardized test specimen preparation.

• ISO 18454 - Standard atmospheres for conditioning and testing footwear and their components, ensuring consistent environmental conditions during testing.

By integrating ISO 10748:2011 testing with these related standards, organizations can maintain high product quality, enhance safety, and comply with global footwear manufacturing requirements.
