2.2.4 Compression Testing<br />
Objective:<br />
Column crush tests provide information about the crushing properties of blown<br />
thermoplastic containers. Column crush properties include the crushing yield<br />
load, deflection at crushing yield load, crushing load at failure, and apparent<br />
crushing stiffness.<br />
Equipment:<br />
Lansmont Corporation Squeezer Compression Tester (0.1 lbs, 0.001 in)<br />
Mettler AE 160 Scale (0.0001g)<br />
Methods:<br />
Crush testing was performed in accordance with ASTM D 2659-95 Standard Test<br />
Method for Column Crush Properties of Blown Thermoplastic Containers (ASTM<br />
