Climbing Ropes vs. Sleeping Bags
Comparing 2 standards across 18 specifications. 18 key differences identified.
Dynamic mountaineering ropes are certified under European standard EN 892 and UIAA 101. Standard classifications include Single Ropes (8.5–10.2 mm diameter, tested with an 80 kg mass to withstand ≥ 5 UIAA factor-1.77 falls with maximum impact force ≤ 12.0 kN), Half Ropes (7.1–9.0 mm, tested with 55 kg mass, ≥ 5 falls, max impact force ≤ 8.0 kN), and Twin Ropes (6.9–8.0 mm, tested paired with 80 kg, ≥ 12 falls, max impact force ≤ 12.0 kN). Static ropes are certified under EN 1891 Type A/B for caving and rescue.
Sleeping bag temperature ratings are standardized internationally under ISO 23537-1 (which superseded European standard EN 13537).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).
