Scope

1.1  This test method2 covers the determination of the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started, using an Elmendorf-type tearing tester. Two specimens are cited, a rectangular type, and one with a constant radius testing length. The latter shall be the preferred or referee specimen. 1.2  Because of (1 ) difficulties in selecting uniformly identical specimens, (2 ) the varying degree of orientation in some plastic films, and (3 ) the difficulty found in testing highly extensible or highly oriented materials, or both, the reproducibility of the test results may be variable and, in some cases, not good or misleading. Provisions are made in the test method to address oblique directional tearing which may be found with some materials. 1.3  The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.4  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 13.1 . Note 1:  Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.). Note 2:  This standard is equivalent to ISO 6383-2. 1.5  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
