(Test Method)Standard Test Method for Evaluation of Mechanical Handling of Unitized Loads Secured with Stretch Wrap Films
Standard Test Method for Evaluation of Mechanical Handling of Unitized Loads Secured with Stretch Wrap Films
SIGNIFICANCE AND USE
This test method is intended for use primarily 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 test results and actual field performance has been established.
This test method simulates mechanical handling anticipated during all distribution phases.
This test method leaves open to the discretion of the user the establishment of test levels and numbers of cycles constituting the test, so that the user might tailor the test to simulate a particular distribution environment. The section on mechanical handling over 100 pounds (45 kg) in Practice D 4169 may provide some guidance in this regard.
SCOPE
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 D 6055 and Test Methods D 6179. 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 and health practices and determine the applicability of regulatory limitations prior to use.
