The user may use the following simple equation for making an approximate calculation: Number of falls 2 metres of climbing x 0.33 + metres of abseiling x 1.66 = metres of use 15 Standard falls 10 Standard falls 5 Standard falls 4 6 8 10 12 x 1000m Rope with 5 standard falls Rope with 10 standard falls Rope with 15 standard falls Formula for calculating Abseiling (m) x 1,66 Climbing (m) x 0,33 cumulated Metres of use Metres of use When documenting the metres of use cumulatively, the user may estimate the safety condition of the rope (safety reserve of the number of falls) from the number of metres of use of the rope since the first day of use. General values of safety condition (safety reserve) According to curves depicted in the graph for individual rope types: TENDON 11.4 mm Trust 20 standard falls on the day of production TENDON 11.0 mm Trust 16 standard falls on the day of production TENDON 10.5 mm Ambition 11 standard falls on the day of production The number of cumulated metres may be used to estimate the remaining safety condition/safety reserve (number of standard falls) of the rope. Estimated safety condition of ropes used with different intensity (TENDON 11 mm Trust): • Safety condition >/= 5 standard falls (up to approx. 6,000-8,000 metres of use) If the rope is in perfect condition, it may be used to secure any climbing situation up to a fall factor of 2. • Safety condition > 2 standard falls (up to approx. 12,000-14,000 metres of use) If the rope is in perfect condition, it may be used to secure any climbing situation up to a fall factor of 1. • Safety condition
especially in combination with heavy performance of the rope, result in abrasion of fine fibres of the core and the sheath. The particles act as abrasive sand and lead to reduction of the load-bearing cross section of the fibres, especially during frequent abseiling. • Loading by falls Due to the low dynamic elongation, loading by falls with a fall factor of 0.3 or greater must be essentially excluded. Because, unlike dynamic ropes, the main task of static ropes does not consist in safe arrest of falls but in a quasi-static loading with a minimum dynamic stress only, a macromolecular stretching occurs when the rope is used correctly which, however, has no adverse effects on the maximum tensile force and the elongation of the rope. In case of an alternating to repeated (cyclic) loading of up to 20% of the maximum tensile strength of the rope with approximately 10,000 loading cycles, a residual force at break of the rope of >75% may be expected. Example: TENDON 11 mm Static • maximum tensile force: 40.0 kN • residual force at break – knot: 16.5 kN • residual force at break after 10,000 cycles of repeated (cyclic) loading of up to 20%(= 6 kN): 30.0 kN The above parameters exceed the minimum requirements of EN 1891 for Type A static rope significantly. 2014 Occasional use (several times a year) with an intensity of use unworthy of notice, without considerable mechanical loading or fall arrest, without recognizable wear or contamination. Frequent use (several times a month) with low intensity of use, without considerable mechanical loading (suspension, occasional lowering or abseiling) or fall arrest. Signs of use: no signs of heavy wear, slight contamination, hardly recognizable hairiness. Occasional use (several times a year) with high intensity of use, mechanical loading (suspension, occasional lowering or abseiling), without fall arrest. Signs of use: slight wear, contamination, negligible hairiness. Very frequent use (several times a week) with low intensity of use, without considerable mechanical loading or fall arrest. Signs of use: signs of heavy wear, slight contamination, recognizable hairiness. Very frequent use (several times a week) with high intensity of use, mechanical loading (suspension), but without fall arrest. Signs of use: signs of wear, obvious hairiness, slight vitrification. Intensive use (every day) with normal intensity of use, without considerable mechanical loading or fall arrest. Signs of use: obvious wear, obvious hairiness, heavy contamination. Intensive use (every day) with high intensity of use, mechanical loading (suspension), but without fall arrest. Signs of use: heavy wear, vitrification, contamination and hairiness. 8 - 10 years 5 - 8 years 3 - 5 years 1 - 3 years
