4.1 This guide is for user selection, specification, and application of stretch film materials. It may be used between the buyer and seller to arrive at purchase specifications.1.1 This guide covers recommended guidelines for the selection, specification, and use of stretch films for unitizing, reinforcing, and palletizing for indoor environments. This can include storage or transport, or both, in warehouses, closed containers such as truck trailers or rail boxcars, and associated transfer terminals. This guide does not cover the performance issues associated with outdoor exposure.1.1.1 Performance characteristics of stretch film may be negatively affected by extreme temperatures.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 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.1.4 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.

5.1 This guide is for testing the performance applied stretch wrapping film and stretch wrapping equipment during and after the film has been applied to a unit load or structure. These tests are not written with the intention for them to be applied to agricultural stretch wrapping films and its application.1.1 This guide covers testing of mechanical properties of stretch wrapping films as they have been applied by a stretch wrapper to a unit load or test structure. This guide may be applied to hand-wrapping or to machine-wrapping applications. These tests may be applied to real-world or “field” testing or may be applied to theoretical or “laboratory” testing. This testing does not cover the testing of mechanical properties independent of application by stretch wrapper.1.2 No statement is made about either precision or bias of any of these test methods since results merely state whether this is in conformation to the criteria for success specified by the user of the test method.1.2.1 The user is encouraged to establish the precision and bias for their own application.1.3 The units used in this standard are SI units (metric) with their English equivalents included following them in parentheses.1.4 These tests are not intended to be applied to agricultural stretch wrapping films and its application.1.5 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.1.6 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.
