Standard Test Method for Compression Resistance of a Container Under Constant Load

SCOPE
1.1 This test method is designed to determine the resistance of a shipping container to a vertically applied constant load for either a specified time or to failure. The test method may also, include, for example, a package of a shipping container, palletized or unitized loads.
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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6.
