Carabiners vs. Sleeping Bags
Comparing 2 standards across 18 specifications. 18 key differences identified.
Climbing carabiners and connectors are certified under European standard EN 12275 and UIAA 121. Major certifications specify minimum breaking strength across three loading axes: Major Axis Closed (standard Type B ≥ 20 kN / Type H HMS ≥ 20 kN / Type K Via Ferrata ≥ 25 kN), Minor (Cross) Axis (≥ 7 kN), and Open Gate (≥ 7 kN for Type B/H, ≥ 8 kN for Type K). Locking mechanisms include Screw-Lock, Auto-Lock (twist-lock 2-stage), and Triple-Lock (lift-twist-open 3-stage).
Sleeping bag temperature ratings are standardized internationally under ISO 23537-1 (which superseded European standard EN 13537). Using a calibrated thermal manikin in a climate chamber, tests establish four standardized temperature metrics: Comfort Temperature (T_comf, where a standard woman sleeps comfortably in a relaxed posture), Limit Temperature (T_lim, where a standard man sleeps in a curled posture without shivering), Extreme Temperature (T_ext, minimum survival threshold for women against hypothermia for 6 hours), and Maximum Temperature (T_max).
