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

Abstract

5.1 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. 5.2 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. 5.3 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 H—Simulated Rail Switching” in Practice D4169 may provide some guidance in this regard.
