Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb. This measures the deflection of the specimen and is used to calculate strain throughout the test.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.
Acceptable core material forms include material with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2.
