Significance and Use
In the distribution system, the packaged product may be stored for a period of time in a manner such that one or more containers are stacked on one another. The bottom package is thus continually subjected to a constant compression load.
This test method subjects an empty container to a predetermined static load and to specified atmospheric conditions, if required, over a short period of time using fixed platen compression testing equipment. Deflection is measured over time.
Deflection versus time data can be used to predict time to failure of corrugated shipping containers under constant load.
1.1 This test method covers determining the resistance of an empty paper corrugated shipping container to a vertically applied constant compression load for a specified time. The test method may also include palletized or unitized loads made of such containers. The boxes are tested in the orientation that they are most likely to be stacked in a unitized or palletized load.
1.2 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.
1.3 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.
