3、ethod permits flexible barrier films andlaminates to be characterized for slow rate penetration resis-tance to a driven probe. The test is performed at roomtemperature, by applying a biaxial stress at a single testvelocity on the material until perforation occurs. The force,energy, and elongation to
4、 perforation are determined.1.2 The values stated in SI units are to be regarded asstandard. The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.3 This standard does not purport to address all of th
5、esafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

9、n probe.4. Significance and Use4.1 Penetration resistance is an important end-use perfor-mance of thin flexible materials where a sharp-edged productcan destroy the integrity of a barrier wrap. This will permitpackage entry/exit of gases, odors, and unwanted contami-nates, causing potential harm to
10、the product and reducingshelf-life. Material response to penetration will vary withnumerous factors, such as film thickness, elastic modulus, rateof penetration, temperature, shape and type of probe. Conse-quently, material responses from puncture to stretch may beobserved and quantified using this
11、method.Although numerouscombinations of experimental factors can be devised and usedto simulate specific end-use applications, the recommendedconditions in this method should be followed for standardcomparisons of materials.5.
