JSP height safety harnesses undergo strict testing procedures to ensure they meet the highest safety standards. Each harness is tested twice—once during production and again before being shipped to the customer. These tests assess both dynamic and static performance to ensure the harness will function correctly in real-life fall scenarios.
Dynamic Testing
The dynamic test simulates a fall and confirms the harness can securely hold a person without failure:
A 100kg test dummy is fitted with the harness.
A 2m length of dynamic rope is attached and anchored to a fixed point.
The dummy is initially lifted 2m off the ground, then raised an additional 2m—creating a fall factor of 2.
The dummy is dropped feet first from a height of 4m.
The harness passes if it keeps the dummy securely held and shows no damage to webbing or buckles.
The same harness is then subjected to a second test:
This time, the dummy is dropped head first, replicating another potential fall position.
Static Testing
This test ensures the harness can handle significant, sustained force:
The harness is subjected to a static force of 15kN (approximately 1,530kg).
It must withstand this force for 3 minutes without breaking.
Post-test inspection ensures there is no failure or damage.
Context for Safety:
During an actual fall, a fall arrest lanyard limits the force to approximately 600kg. JSP harnesses are therefore tested to more than 2.5 times this level to ensure absolute reliability under extreme conditions.
Key points:
JSP harnesses are tested both during production and before delivery.
Dynamic testing simulates a 4m fall in both feet-first and head-first orientations.
Static testing subjects harnesses to 15kN of force for 3 minutes.
Harnesses must show no damage or failure to pass testing.
Testing exceeds the forces encountered during real-world falls for maximum safety.
