ASTM D5415-95(2007)

Standard Test Method for Evaluating Load Containment Performance of Stretch Wrap Films by Vibration Testing

SIGNIFICANCE AND USE
This test method is intended to be used mainly as a means of comparing the performance of stretch-wrap films. It can also be used to compare the effectiveness of different wrap cycles with the same wrapping materials. No direct correlation between these test results and actual field performance has been established.
This test method simulates the shipping of unitized loads by way of truck and rail, concentrating on the vibration element associated with these modes. Other elements of the distribution system, such as mechanical handling, are not addressed specifically in this test method.
This test method establishes a method for rating the performance of films, but it leaves open to the discretion of the user the establishment of an acceptable rating for the specific end-use intended.
SCOPE
1.1 This test method is used to evaluate and compare the ability of stretch-wrap films to contain unitized loads during shipping.
1.2 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.
