CONTRACT TESTING PROGRAM

The Center assists pallet and container manufacturers and their customers to develop new, more efficient pallet, packaging, and equipment designs. Under the Contract Testing Program, research results will be proprietary. Investments of the testing sponsors are protected.

Pallet Component Tests: Bending Strength, Stiffness

Component tests evaluate the bending strength and stiffness of pallet parts. These properties can be used to predict the performance of a pallet. Testing follows ASTM D198.

Pallet Tests: Strength/Stiffness, Durability

Pallet tests are divided into two categories: strength/stiffness and durability. The test protocol is described in ASTM D1185 or ISO 8611. The strength/stiffness evaluation is dependend on the pallet support condiditons. Typical supports include warehouse floor stacking, racking across length, racking across width, and conveyor chain. The load is applied using a uniform, flexible airbag as a genral purpose load. Specific loads can also be used during testing. Pallet durability is determined using the incline impact tester to impact the end board or stringer/post with a fork tine. The corner drop test is also used.

Package Tests: Compression, Distribution

Pallet tests are divided into two categories: strength/stiffness and durability. The test protocol is described in ASTM D1185 or ISO 8611.

Pallet durability is determined using the incline impact tester to impact the end board or stringer/post with a fork tine. The corner drop test is also used.

Unit Load Testing

Testing of full unit loads often falls under the same ASTM and ISTA protocol listed above. Another area of unit load testing is load stability. Unit loads are tested using vibration and simulated warehouse handling. Stability tests ensure that the unit load will remain intact throughout the distribution cycle.

Fastener Tests

Testing of full unit loads often falls under the same ASTM and ISTA protocol listed above. Another area of unit load testing is load stability. Unit loads are tested using vibration and simulated warehouse handling. Stability tests ensure that the unit load will remain intact throughout the distribution cycle.
