SIST EN 18152:2026

• Abstract:

  This standard specifies the dimensions and characteristics of the interfaces, requirements, test methods and marking of ski mountaineering boots and clip-on binding crampons which are fixed together with attachment at the boot toe and boot heel, the proper fixed function of which depends on the dimensions and design of the interfaces.

SIST EN 18152:2026 is the Slovenian national adoption of EN 18152:2026 from CEN for mountaineering equipment - Interfaces between ski mountaineering boots and clip-on binding crampons - Requirements and test methods. It specifies the interface dimensions, functional requirements, test methods, marking and user information for ski mountaineering boots and clip-on binding crampons that lock together at the boot toe and heel. Manufacturers, test laboratories, ski shops and buyers use it to check whether a boot and crampon are designed to work as a compatible system.

What does SIST EN 18152:2026 specify?

SIST EN 18152:2026 specifies the dimensions and characteristics of the interfaces between ski mountaineering boots and clip-on binding crampons, plus the related requirements, test methods and marking. It applies to the boot-to-crampon connection at the toe and heel, where proper retention depends on interface shape and size.

The standard is organized into seven clauses and one informative annex:

Annex	What it covers
Annex A	Standards on mountaineering equipment

Clauses 1 to 3 cover scope, normative references, and terms and definitions. Clause 4 gives the general requirements, Clause 5 gives the test methods, Clause 6 covers marking, and Clause 7 covers manufacturer’s instructions and information.

What are the key requirements of SIST EN 18152:2026?

Interface design and geometry

• Clause 4.1.1 requires the toe interface and heel interface to be free of sharp edges and burrs that could injure the user or cause cutting or abrasion. In practice, this is a basic safety check on the boot’s contact areas.
• Clause 4.1.2 requires the ski mountaineering boot toe dimensions to match Figure 2, and Clause 5.2 verifies this with the toe test body defined in the CAD file Test bodies.stp. This gives manufacturers and labs a fixed geometry check for the front attachment.
• Clause 4.1.3 requires the heel interface dimensions to match Figure 3, and Clause 5.3 checks this with the heel test body from the same CAD file. The heel shape is critical because the rear clip-on binding depends on it.

Performance, fit and material properties

• Clause 4.2.1 requires that, in walking mode, no part of the cuff touches the heel test body. Clause 5.4 sets out the walking-mode setup, including removal of the liner and positioning of the cuff. This matters because the boot must move without unwanted contact at the rear.
• Clause 4.2.2 requires the hardness of the toe and heel interface areas to be at least Shore D 50 at (23 ± 2) °C, tested according to EN ISO 868:2003. In practice, this controls the stiffness of the interface areas so they keep their shape in use.
• Clause 4.2.3 requires the crampon to fit the boot 3D dummy, and Clause 5.6 describes fitting it according to the crampon manufacturer’s instructions. This checks real compatibility, not only nominal dimensions.

Marking and user information

• Clause 6 requires clear, indelible and durable marking with the manufacturer name, model identification if relevant, and the reference to EN 18152 on the ski mountaineering boot. This helps users and inspectors identify compatible products.
• Clause 7 requires an explanatory leaflet with compatibility and inspection information, including the need to check that the boot is marked EN 18152 and to verify boot-crampon size compatibility in a safe place before use. That supports correct selection and safer first use.

What terms does SIST EN 18152:2026 define?

• ski mountaineering boots - Ski boots intended for ski mountaineering and compatible with suitable ski bindings; the definition gives examples such as pin-tech inserts, touring ski-boots ISO 9523:2023, and alpine boots with improved walking soles ISO 23223:2025.
• clip-on binding crampons - Crampons conforming to EN 893:2019 that use both the toe interface and the heel interface to attach to ski mountaineering boots.
• toe interface - The front part of the boot intended to fit with the front clip-on binding.
• heel interface - The rear part of the boot intended to fit with the rear clip-on binding.
• rigid sole - A boot sole that does not flex when walking.

Who uses SIST EN 18152:2026?

Manufacturers of ski mountaineering boots and clip-on binding crampons use this standard when designing the interface shape, choosing materials and writing product instructions. Test laboratories use it when checking geometry, hardness and fit with the specified test bodies and dummy.

Quality managers, buyers and technical reviewers use it to verify compatibility claims and to confirm that markings and user information are present. Ski shops and trained technicians can also use it when checking whether a boot and crampon are the right match before use.

Which standards are used with SIST EN 18152:2026?

• EN ISO 868:2003 - Used in Clause 5.5 for Shore hardness testing of the toe and heel interface areas.
• EN 893:2019 - Named in the definition of clip-on binding crampons as the crampon standard they conform to.
• ISO 9523:2023 - Named in the definition of ski mountaineering boots as an example of a compatible touring ski-boot interface standard.
• ISO 23223:2025 - Named in the definition of ski mountaineering boots as an example of an alpine ski boot with improved walking soles.

Annex A also points readers to the wider mountaineering equipment standards family.

What does the SIST EN 18152:2026 document contain?

SIST EN 18152:2026 includes figures for the toe and heel interface dimensions, the walking-mode cuff clearance check, and the boot 3D dummy fitting check. It also specifies test bodies defined by the CAD files Test bodies.stp and boot 3D dummy.stp, which are used to verify geometry and crampon fit.

The document contains the marking rules and the leaflet content that manufacturers must supply with the boots and crampons. Annex A contains Table A.1, a list of related mountaineering equipment standards. The bibliography names EN 893:2019, ISO 9523:2023 and ISO 23223:2025.
