Overview - prEN 15151: Mountaineering equipment - Descenders
prEN 15151 (draft CEN standard) specifies safety requirements and test methods for descenders (braking devices) used in mountaineering and climbing. Prepared by CEN/TC 136, the document sets design, braking performance and strength criteria, plus marking and information that manufacturers, test laboratories and conformity assessors should provide. Keywords: prEN 15151, descenders, mountaineering equipment, braking devices, safety requirements, test methods, CEN.
Key topics and technical requirements
- Design requirements
- Attachment opening minimum: 13 mm (measured with a 13.0 +0.1 mm bar).
- Edges in contact with fingers must be free of burrs; specified edge geometry illustrated in the standard.
- Braking capacity
- Performance test requires a force multiplier k > 7, calculated from recorded maximum force.
- Test setup: rope entry/exit angle (30 ± 5)°, jack speed (1000 ± 300) mm/min, applied mass (10 ± 0.1) kg, and rope knotability K between 0.6 and 0.8.
- Strength requirements
- Attachment opening must resist (12 ± 0.1) kN applied via a 10 mm pin without breaking.
- Braking part must withstand (5 ± 0.1) kN with no deformation impairing function.
- Test conditions
- Conditioning temperature: (23 ± 5) °C.
- Tests performed with the minimum rope diameter marked on the device (single or two-strand configurations as applicable).
- Information and marking
- Manufacturers must supply name/trademark, standard reference (EN 00136079), meaning of markings, intended use, maintenance/service instructions, and product lifespan.
- Devices must be marked with manufacturer and minimum rope diameter using the ∅ symbol (e.g., min. 1x ∅ 10.5).
Practical applications and users
- Manufacturers of descenders use prEN 15151 to design products that meet European safety expectations and to prepare technical documentation and marking.
- Test laboratories and certification bodies apply the specified test methods (braking capacity, strength, conditioning) to verify compliance.
- Retailers, safety officers and purchasing agents rely on the standard’s marking and information requirements when selecting equipment for climbing, mountaineering courses, guided expeditions and professional rope access.
- Climbers and instructors benefit indirectly through clearer product labels (minimum rope diameters, maintenance guidance, lifespan).
Related standards
- Referenced standards: EN 892 (dynamic ropes), EN 1891 (low-stretch ropes), EN 12275 (connectors). See Annex A for a wider list of mountaineering equipment standards.
- prEN 15151 supports conformity to EU Directive 89/686/EEC (personal protective equipment) as noted in Annex ZA.
This standard is essential for ensuring safe descender design and consistent testing across manufacturers and certifiers in Europe.
