Gardner Impact Testing
Gardner Impact Testing
(OP)
My question is in regard to material testing, specifically Gardner Impact testing. I read ASTM D5420 (Gardner Impact) and it says that the results are in units of inch pounds. I have a document from a former vendor that states that the impact test on material furnished to us is in units of in-lb/mil. Can anyone explain this to me.
Thanks
Thanks

RE: Gardner Impact Testing
Gardner impact testing measures the energy needed to cause fracture, therefore the units need to be in terms of energy. Joules (J) are the preferred, SI notation for ASTM D 5420, with pound force-inch also being a unit of measure for energy. in-lb/mil is not appropriate.
