10、educing shelf-life.Material response to penetration will varywith numerous factors,such as film thickness,elastic modulus,rate of penetration,temperature,shape and type of probe.Consequently,material responses from puncture to stretch maybe observed and quantified using this method.Althoughnumerous
11、combinations of experimental factors can be devisedand used to simulate specific end-use applications,the recom-mended conditions in this method should be followed forstandard comparisons of materials.5.Apparatus5.1 Universal Testing Apparatus,with a recording device.5.2 Compression Load Cell(s).5.3
