Box Compression Strength Tester - U500/1000-S by PackTest.com

A corrugated shipper / carton’s primary purpose is to protect the unit packaging inside and prevent any undue stress to reach the product. The carton has to withstand the stress of stack load in warehousing and transportation. If the carton is stronger than the stack load, the products will survive. If the carton is weak, the carton will collapse and pass on the load to the inner packs.
Carton Compression Specification = Stacking Load x Safety Factor.
Safety factor is usually between 3-7 and depends on a lot of factors including product fragility, product cost, distribution cycle, transit period, transportation methods, etc.
This test is a typical “Performance Test” and a good compression strength directly signifies a good carton.
Test Method :
The test specimen is placed between 2 parallel platens of a compression tester and pressed. The max load it can bear before the carton collapses is recorded as the Compression Strength.
Test Standard : TAPPI T-804 / ASTM D 642 / ISO 12048 / IS 7028

Very useful

What is the threshold value? How can we guess at which pressure the test has passed?

[@PackTestMachinesInc]

You dont have to guess anything. Initially the load starts to increase on the carton. When the carton cannot withstand the load anymore, it starts to collapse / buckle. The force starts to reduce. Threshold Value is the percentage of force reduction you want to allow before the machine auto stops. So basically if the peak force of a carton is 500 kgf and the reading falls by 10% (50 kgf), the machine will stop and the test is completed. Now if we set the threshold to 20%, the machine will wait for a reduction of 20% from 500. i.e. 100 kgf before stopping. This doesnot change the Peak or Result. It only defines when to stop "After" the peak is achieved. Hope we were able to help today.

@@PackTestMachinesInc Got it, thank you

Is that double, triple or single layer cardboard

[@PackTest]

I think the sample was a 7 ply (Double Wall) Corrugated board. But the machine is common for all types.
