4.1 Compressive resistance is one of the properties used to evaluate the ability of shipping containers, components, and unit loads to successfully survive the compressive forces they are subjected to during storage and distribution (see Note 1). Note 1: For constant load test refer to Test Method
D4577.
4.2 Compressive resistance may be determined with either fixed- or swiveled-platen-type testing machines. However, a fixed-head compression machine is required to perform edge-to-edge and corner-to-corner orientations on test specimens (see Note 2). Also, unit loads are generally tested only in the top-to-bottom orientation. Note 2: Fixed-platen machines generally cause corrugated box
specimens to fail at their strongest point, while swivel-platen
machines cause corrugated box specimens to fail at their weakest
point.1.1 This test method covers compression
tests on shipping containers (for example, boxes and drums) or
components, or both. Shipping containers may be tested with or
without contents. The procedure may be used for measuring the
ability of the container to resist external compressive loads
applied to its faces, to diagonally opposite edges, or to corners.
This test method covers testing of multiple containers or unit
loads, in addition to individual shipping containers, components,
materials, or combination thereof.
1.2 The test method of applying load may be used to compare the characteristics of a given design of container with a standard, or to compare the characteristics of containers differing in construction. 1.3 This test method is related to TAPPI T 804. This test method fulfills the requirements of International Organization for Standardization (ISO) Test Method 12048. The ISO standards may not meet the requirements for this test method. 1.4 The test may be conducted with the container loaded with contents and interior packaging in cases where the contents share the load. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
