JPB SYSTEME - The Best Way For Self Locking Devices

Test and Validation

All of our products have been extensively tested and validated for several thousand cycles to meet the customer’s needs.

Shock resistance

Vibration endurance

Leak and pollution test

Tear off test

Torque test

High temp cycle endurance

…

Furthermore, JPB Système’s Lockwire Anti-rotational Devices have been industry proven and in service for over 10 years...

Here is an abstract of testing process:

SHACKING TABLE TEST:

Sinus test 3Hz to 4000Hz
Level 1G to 100g cc
Sweep : 2oct /min

	On the right: a classic plug (without JPB Système’s Lockwire Anti-rotational Device) torqued by hand.
	On the left: a JPB Système’s Lockwire Anti-rotational Device NOT torqued, Locking Tabs just engaged (WORST CONDITION).

RESULTS:

Vibration Loosening of classic Bolts after 1Hour of testing.

IMPOSSIBLE to loose the JPB Système’s under Vibration (test duration: 48H)

Abstract of ELS and ELS Light shacking table test.
Simulation of Fan Blade Off event (FBO).
Test under presure : 5080 psi -350 Bar

Test of Self-Locking. The plug will automatically lock on the 2nd turn if the first one failed.

This is the most critical frequency. We run the shacking table at 525Hz with acceleration 50g cc.

Note: The resonance phenomenon is visible with the stroboscope light.

RESULT: More that 3 million of cycles passed with success.

Endurance test: resonance frequency of the spring.
