Standard Guide for Performance Testing of Applied Stretch Films and Stretch Wrapping
NORMA vydaná dňa 1.10.2020
|Significance and Use|
5.1This 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.
1.1This 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.
1.2No 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.
1.2.1The user is encouraged to establish the precision and bias for their own application.
1.3The units used in this standard are SI units (metric) with their English equivalents included following them in parentheses.
1.4These tests are not intended to be applied to agricultural stretch wrapping films and its application.
1.5This 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.
1.6This 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.
