1、Designation:D457719Standard Test Method forCompression Resistance of a Container Under ConstantLoad1This standard is issued under the fixed designation D4577;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A
2、 number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is designed to determine the resistanceof a shipping container to a vertically applied constant load foreither a specifie
3、d time or to failure.The test method may alsobe used for palletized or unitized load configurations.1.2 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and
4、environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific precautionary statements,see Section 6.1.3 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision
