EN 1497: 2007 Rescue Harnesses

  EN 1497: 2007 Rescue harnesses   Rescue harnesses are used when it is required to lower or raise an individual, normally in the event of an emergency. A rescue attachment point may be incorporated into a full body harness used in a fall protection system allowing a user to be rescue following the event of a fall. Ergonomics To ensure a rescue harness has a relative degree of comfort, ergonomic trials are carried out on two users with differing weights and heights. This test requires each user to be suspended for 4 minutes and then assessed by visual inspection and questions to see if there was an acceptable level of comfort. Dynamic Performance Rescue harnesses are subjected to a drop test to generate a shock load on the product. A lesser force is applied to a rescue harness attachment point compared with fall arrest harness attachments as the possibility of a period of free-fall is significantly less in use. Rescue harnesses are subjected to a 1 metre drop using...

EN 354:2010 Lanyards

  EN 354:2010 Lanyards   Lanyards intended for use in connecting the attachment point of a harness to a suitable anchorage device. This type of lanyard is intended for use as a component of a larger system, which should include a shock absorbing element. Slippage Lanyards are subjected to a force of 6kN for 3 minutes, before then being assessed for slippage through the adjustment element which cannot be anymore than 50mm. This test is done following ambient conditioning and after being placed in water and a freezer at -4°C. There is also an optional test for extreme cold for any products claiming use in temperatures below -30°C. This test is only applicable for lanyards that include an adjustment element. Static Strength Metallic lanyards are subjected to a tensile force of 15kN and non-metallic lanyards are subjected to a tensile force of 22kN for a minimum period of 3 minutes. This test is done following ambient conditioning and after being placed in water and a ...

EN 813:2008-Sit Harnesses

  EN 813:2008-Sit harnesses Dynamic Performance Sit harnesses are subjected to a drop test to generate a shock load on the product. A lesser force is applied to the sit harness attachment point compared with fall arrest harness attachments as the possibility of a period of free-fall is significantly less in use. Sit harnesses are subjected to a 2 metre drop using the maximum rated load dummy and they are required to safely arrest the fall following the drop. Static Strength Sit harnesses are subjected to a force of 10 times the maximum rated load but at least a minimum of 15kN for 3 minutes. The harness is required to hold the load without failure of any component part. 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, which is filled with a salt-water mist, which can induce ...
