Loose Cargo Bounce Testing

Ingress Protection Testing

Testing the vibration of unsecured cargo is essential to ensure that it can withstand the shipping environment both physically and functionally. Vibration tests such as the military standard vibration test, the ISTA series 1 and 2, and the Keystone process are utilized to examine loose cargo. The vibration tests simulate the continuous impact environment that cargo traveling in these circumstances would experience, allowing the cargo to bounce, bump into other goods, and collide with them.

The military standard vibration test involves the use of restraints to prevent relative motions while ISTA series 1 and 2 are used for package testing. ISTA 1C, 1D, and 2 series cover even more diverse variables, including air, temperature, humidity, and compression testing.

Testing on loose cargo allows us to determine how well a material performs and can endure vibration exposure. This is important as vibrations may cause mechanical wear and fatigue, affect components and/or interrupt functioning, and lead to damaged wiring, loose parts, electrical contacts that come and go, mechanical or optical misalignment, particle migration, failing parts becoming stuck in circuits or systems, electrical mismatches, defective seals, and defective parts.
