ABSTRACT:
A method and apparatus for testing a pellet of resin to determine its age comprises preheating the pellet and subjecting it to a deformation force in a measurement fixture for a predetermined time period. At the expiration of the predetermined time period, the deformation of the pellet is measured and compared to an expected deformation of the resin as a function of the resin age to determine the age of the pellet.
