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

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.

Precision and Bias313.1 Precision:13.1.1 Table 1
30、 and Table 2 are based on a round robinconducted in 198889 in accordance with Practice E691,involving six materials tested by six laboratories. For eachmaterial, all the samples were prepared at one source, but theindividual specimens were prepared at the laboratories whichtested them. Each test res
31、ult was the test value of an individualdetermination. Each laboratory obtained five test results foreach material. Each laboratory tested each material two ways,each of which is treated as a separate material.13.1.1.1 Table 3 and Table 4 are based on the same roundrobin discussed above, but the data
32、 is based on three and fourlaboratories respectively and should be used with caution dueto the small amount of data.NOTE 2The following explanations of r and R (13.1.2 through13.1.2.3) are only intended to present a meaningful way of considering theapproximate precision of this test method.

38、ial, obtained by the same operatorusing the same equipment on the same day.) The two testresults should be judged not equivalent if they differ by morethan the r value for that material.13.1.2.2 Reproducibility Limit, R(Comparing two testresults for the same material, obtained by different operators
39、using different equipment in different laboratories.) The twotest results should be judged not equivalent if they differ bymore than the R value for that material.13.1.2.3 Any judgment in accordance with 13.2.1 or 13.2.2would have an approximate 95 % (0.95) probability of beingcorrect.13.2 BiasThere
