Can ECT board be used for UN tested cartons

Randy asks,

I asked this question a number of years ago but I was wondering if ECT Board can be used for UN Tested cartons or is Mullen tested board still the only thing that can be used?

That’s probably a yes and no answer. ECT is allowed as long as the packaging can pass an UL testing protocol and the liner weights do not vary by more than 5%. A wider 10% range has been approved and included in the most recent version of the 49CFR.

Don’t forget about the maximum Cobb test.
