ASTM D642-00 pdf free.Standard Test Method for Determining Compressive Resistance of ShippingContainers, Components, and Unit Loads.
This test method covers compression tests on shippingcontainers (for example, boxes and drums) or components， orboth. Shipping containers may be tested with or withoutcontents.The procedure may be used for measuring the abilityof the container to resist external compressive loads applied toits faces, to diagonally opposite edges, or to corners (Fig. 1 andFig. 2).This test method covers testing of multiple containersor unit loads， in addition to individual shipping containers,components， materials， or combination thereof.The test method of applying load may be used tocompare the characteristics of a given design of container witha standard,or to compare the characteristics of containersdiffering in construction.This test method is related to TAPPI T804，which issimilar for fixed platen machines but does not recognize swivelplaten machines.This test method fulfills the requirements ofInternational Organization for Standardization (ISO)TestMethod 12048.The ISO standards may not meet the require-ments for this test method.
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 and health practices and determine the applicability of regulatory limitations prior to use.
Bring the platens into contact with the specimen apply-ing an initial pressure or pre-load.For singlewall corrugated containers, an initial forceor pre-load of 50 1bf(222 N)on the specimen is recommended.For double-wall and triple-wall boxes，pre-loads of 100 lbf(445N) and 500 1bf (2220 N) respectively are recommended.For other types of test specimens a suitable pre-load may ormay not be selected.Fixed platen machines must be used for tests where thecompressive loads are applied on test specimen edges， or ondiagonal corners (Fig.1). Either fixed-platen or swivelplatenmachines may be used for face-to-face compressive tests (Fig.2).If the testing machine is not fitted with a load-deformation recorder, record the test load for every 0.1 in. (2.5mm) of deformation of the container (see 9.4.1). Set theload-deformation recorder to display zero deformation. When testing full containers,and the load sensingdevice is located under the bottom platen, be sure to zero thetest machine with the product on it, or subtract the containerweight from peak load readings.ASTM D642 pdf download.
