PERFORMANCE 24-48 REQUIREMENTS AND TEST METHODS FOR FULL BODY HARNESS

The EN 361 standard applies to full body harnesses that are meant to keep the user in place and distribute the load in the event of a fall (i.e., being brought to a stop following a period of free-fall).

THERE ARE 3 MAIN PERFORMANCE TESTS IN EN361

PERFORMANCE IN A DYNAMIC ENVIRONMENT
This test simulates the behaviour of the harness in a real-life situation by submitting it to a shock test with a load that is larger than what it would experience in use. The angle at which the user is held in the event of a fall is given special attention. A 100kg solid torso dummy is secured to a 2-metre length of 11mm mountaineering rope fastened to a solid anchorage point and dropped for 4 metres in free fall.

Each harness is tested twice, once from a heads-up position and once from a heads-down position (i.e., with the dummy upside down on release). To pass the test, the harness must retain the dummy in a position that is not more than 50 degrees from upright after both drops.

TENSILE TESTS (STRENGTH TESTS)
Pressure is typically applied for at least three minutes to determine that the product's breaking strength exceeds the force stipulated by the standard. These are calculated on a 6kN safety factor, where KN stands for Kilonewtons, a unit of force.

  • Harnesses are exposed to 15kN in an upward direction and 10kN in a downward direction when applied.
  • Depending on the materials used, lanyards are exposed to 22kN or 15kN applied between the attachment sites.
  • CORROSION RESISTANCE
    The aim of this test is to prove that metallic components used in fall protection equipment can withstand a minimal resistance to environmental corrosion (specifically rust). In order to prove this, metal components are placed in a sealed chamber for 24 to 48 hours and subjected to saltwater mist designed to induce rust in unprotected metals. They are then examined for rust and function afterwards
