FprEN 18152 - Mountaineering equipment - Interfaces between ski mountaineering boots and clip-on binding crampons - Requirements and test methods

Overview

The European standard oSIST prEN 18152:2025:2025 defines the interfaces between ski mountaineering boots and clip-on binding crampons, setting out indispensable requirements and test methods to ensure compatibility, safety, and performance. Developed by CEN Technical Committee CEN/TC 136 and based on prior standards including ISMF 104:2018, this updated draft standard addresses the dimensions, characteristics, and mechanical features essential for reliable attachment between mountaineering boots and clip-on crampons. The standard enables manufacturers and users to verify the interface design, ensuring secure fit and functionality.

Adherence to oSIST prEN 18152:2025 supports manufacturers in producing ski mountaineering equipment that meets rigorous safety and functional expectations. It covers design requirements, test procedures, and marking guidelines to assure product consistency throughout the industry.

Key Topics

  • Scope and Definitions
    Specifies the physical dimensions and interface characteristics at the boot toe and heel critical for clip-on crampons attachment. Defines key terms such as ski mountaineering boots, touring ski boots, alpine ski boots with improved walking soles, clip-on binding crampons, toe and heel interfaces, and rigid soles.

  • Design Requirements

    • Innocuousness: Interfaces must be free from sharp edges or burrs to prevent user injury and equipment damage.
    • Dimensional Specifications: Exact measurements for toe and heel interface areas are provided, including defined tolerances to ensure universal compatibility.
    • Performance Features: Cuff movement in walking mode must maintain clearance from the heel interface; hardness of interface materials is standardized (minimum Shore D 50) to guarantee durability and rigidity needed for safe operation.

  • Test Methods
    Practical tests include tactile and visual checks for surface safety, dimensional verification using standardized 3D test bodies, cuff clearance tests to ensure free cuff movement, hardness testing per ISO 868, and crampon fitting assessment using a 3D boot dummy. These methods empower manufacturers and testers to objectively validate product compliance.

  • Marking and Documentation
    Products must be clearly labeled with manufacturer name, model identification, and a pictogram indicating compatibility with the clip-on binding system. Manufacturers are also required to provide detailed user instructions explaining compatibility, safety warnings related to aging and wear of boots and crampons, and guidance on component selection.

Applications

  • Industry Use
    This standard applies directly to manufacturers producing ski mountaineering boots and clip-on crampons, especially for products requiring precision attachment interfaces for safety and performance in alpine terrain.

  • Quality Assurance
    Product developers and testing laboratories use oSIST prEN 18152:2025 to certify their equipment meets consistent standards across design and materials, reducing risks related to improper fit or interface failure.

  • Consumer Safety
    Enhances user confidence by setting a harmonized framework for equipment compatibility, reducing the likelihood of accidents due to interface malfunction or misfit during technical mountaineering and ski touring activities.

  • Market Harmonization
    Facilitates cross-border trade by providing a clear benchmark that CEN member countries adhere to, allowing standardized labeling and reliable interchangeability between boots and crampons from various manufacturers.

Related Standards

oSIST prEN 18152:2025 is part of a comprehensive group of mountaineering standards maintaining high safety and performance levels across climbing and skiing gear:

  • EN 893:2019 – Mountaineering equipment - Crampons – Safety requirements and test methods
  • ISO 9523:2019 – Touring ski boots
  • ISO 23223:2021 – Alpine ski boots with improved walking soles
  • EN 564:2023 to EN 13089:2011 – Various standards covering slings, ropes, ice anchors, helmets, ice-tools, harnesses, and braking devices for mountaineering use

Together, these standards establish a robust framework for safe and compatible alpine sports equipment, with oSIST prEN 18152:2025 focusing specifically on the critical interface between ski mountaineering boots and clip-on crampons.

By implementing and complying with oSIST prEN 18152:2025, manufacturers, retailers, and end users benefit from enhanced safety protocols, seamless equipment compatibility, and reproducible testing methods that promote confidence and innovation in the ski mountaineering community. This standard serves as an essential reference guiding equipment design, quality control, and product information for optimized mountaineering experiences.
