ASTM D5331 : 03(2024)

1.1 This test method covers evaluation and comparison of the ability of unitizing films to survive various methods of mechanical handling.

1.2 The test method described is applicable to common means of material handling, including the following: forklift, push/pull, clamp truck, crane, and spade lift-type handling systems.

1.3 The test levels may be varied to reflect known levels of intensity accurately for the specific unit load under testing.

1.4 The methodology of performing the mechanical handling tests is described in detail in Test Methods D6055 and Test Methods D6179. This test method will describe only sample preparation and evaluation in the special case of evaluating the performance of stretch film for load unitizing.

1.5 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.

1.6 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.

1.7 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.
