Mountaineering Harnesses
Harnesses intended to hold the user in place and spread the load in the case of a fall whilst at the same time being comfortable for use in mountaineering, climbing and abseiling. Mountaineering harnesses come in a number of different designs depending on the application required. These are Type A (Full body harness), Type B (Small body harness), Type C (Sit harness) and Type D (Chest harness).
General
All harnesses are required to have the following as standard:
Load transmitting parts to have a minimum width requirement depending on type and location on body
All threads to be contrasting colour or surface appearance to tape
No sharp edges or burrs on components or textiles.
Strength
Whole products are subjected to tensile tests on all applicable attachment points. Harnesses are subject to a 15/10kN tensile force applied in the upward direction, followed by a 10/7kN force applied downward (force dependant on harness type). Tensile forces are usually applied and held for between 1 and 3 minutes, to ensure the breaking strength of the product is in excess of the force specified by the standard. There is also a requirement that the slippage of buckles or adjusting devices does not exceed 20mm following the load being removed.
