Standard Test Method for Evaluation of Horizontal Impact Performance of Load Unitizing Stretch Wrap Films

Significance and Use:

This test method is intended to be used mainly as a means of comparing the performance of unitizing films. It can also be used to compare the effectiveness of different wrap cycles with the same wrapping materials. No direct correlation between these tests results and actual field performance has been established.

This test method simulates the horizontal impact elements of the distribution environment. Horizontal impacts are encountered in rail car switching and pallet marshalling procedures, both in the warehouse and during the loading and unloading of transport vehicles.

This test method leaves open to the discretion of the user the establishment of test levels and the number of impacts constituting the test so that one might tailor the test to simulate one's particular distribution environment. The section entitled Element HSimulated Rail Switching in Practice D4169 may provide some guidance in this regard.

Scope:

1.1 This test method is used to evaluate and compare the ability of stretch-wrap films to survive horizontal impacts in a laboratory simulation.

1.2 The test levels may be varied to represent the mode of shipping and handling used for the unit load under test.

1.3 The methodology of performing the controlled horizontal impacts is described in detail in Test Methods D4003. This test method will describe only sample preparation and evaluation in the special case of evaluating the performance of film for load unitizing.

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 and health practices and determine the applicability of regulatory limitations prior to use.
