Fall Protection-EN 795:2012 - CEN/TS 16415:2013
EN 795:2012 & CEN/TS 16415:2013
Anchor devices
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: 2012 (1 user) & CEN/TS
16415: 2013 (2+ users) 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.
Dynamic Performance
Anchor
devices are subject to a series of drop tests carried out on the device fixed
as intended, in every intended direction of use and for the number of users
claimed. This can mean a series of tests with the device fitted to a number of
different substrates, as devices need to be installed as it would be used
(often fitted to sample roof surfaces or structures). The tests required are
dependent on the class of the device.
Static Strength
Whole
anchor products are subjected to tensile tests. The test force is 12kN or 18kN
if there is any non-metallic load bearing element. This force is then increased
by 1kN for each additional user claimed. 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.
Corrosion Resistance
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 filled
with a salt-water mist, which can induce rust in unprotected metals. Products
are subjected to 48 hours exposure and examined for rusting and function
afterward.
