Devices intended to form the interface between the fall arrest system (harnesses, lanyards, retractable lanyards etc.) and the structure. These can be in the form of single bolts, slings, deadweight devices or anchor systems (rails or cables). EN 795 classifies anchor devices in the following manner:
- Type A – anchor device with one or more stationary anchor points, while in use, and with the need for a structural anchor(s) or fixing element(s) to fix to the structure
- Type B – anchor device with one or more stationary anchor points without the need for a structural anchor(s) or fixing element(s) to fix it to the structure
- Type C – anchor device employing a flexible anchor line which deviates from the horizontal by not more than 15° (when measured between the extremity and intermediate anchors at any point along its length)
- Type D – anchor device employing a rigid anchor line which deviates from the horizontal by not more than 15° (when measured between the extremity and intermediate anchors at any point along its length)
- Type E – anchor device for use on surfaces up to 5° from the horizontal where the performance relies solely on mass and friction between itself and the surface.
Anchor devices are subject to a series of drop tests carried out on the device fixed as intended, in every intended direction of use. This can often mean a series of tests with the device fitted to a number of different substrates. This can often mean testing on a very large scale, as devices need to be installed as it would be used (often fitted to sample roof surfaces or structures). The tests required are dependant on the class of the device.
Whole anchor products are subjected to tensile tests. These forces are usually between 12kN and 18kN depending on the type of anchor device. Tensile forces are applied and held for at least 3 minutes, to ensure the breaking strength of the product is in excess of the force specified by the standard.
Metallic components used in fall protection equipment are subjected to a neutral salt-spray test intended to prove a minimum resistance to environmental corrosion (specifically rust). Products are held within a sealed chamber, which is filled with a salt-water mist, which can induce rust in unprotected metals. Products are subjected to two periods each of 24 hours exposure, separated by a 1 hour drying period, and examined for rusting and function afterward.
