6、mmended Practice for Choice of Sample Size to Estimate the Average Quality of a Lot or Process3 3.Significance and Use 3.1 This test method is used to provide an indication of the ability of a box to withstand the damage which can be caused by the sudden shock induced by dropping a package.It simula
7、tes those shocks that are likely to occur in the handling of packages through a variety o(distributions cycles and the ability of the box to protect the contents against these shocks.The test may also permit observation of progressive failure of the box and damage to the contents.3.2 Drop tests are
8、performed with either of the two following objectives(see Annex AI),either objective being of value for comparing the characteristics of a package design to a standard or for comparing differences in package construc-tion:3.2.1 Objective A-To measure the ability of the shipping container to withstan
9、d rough handling.I This test method is under the jurisdiction of ASTM Committee 0-10 on Packaging and is the direct responsibility of Subcommittee D I 0.22 on Handling and Transportation.Current edition approved March 3,1980.Published May 1980.Originally published as D 775-44 T.Last previous edition
10、 D 775-61(1973).2 Annual Book 0/ASTM Standards,Vol 15.09.3 Annual Book 0/ASTM Standards,Vol 14.02.121 3.2.2 Objective B-To measure the ability of the package(shipping container and interior packing materials)to protect its contents.3.3 These procedures are also particularly suitable for boxes that a
11、re normally handled manually.Boxes of such bulk or mass that they cannot be handled manually may be more satisfactorily tested in accordance with Methods D 880 and D 1083.4.Apparatus 4.1 Drop Test Apparatus-The drop test equipment shall conform to the following requirements:4.1.1 Permit the box to b
12、e placed in a position,prior to release,that will assure correct orientation,within 2 for flat-face drops and 10 for edge and comer drops upon impact.4.1.2 Permit accurate control of the drop from specified heights.4.1.3 Utilize lifting devices that will not damage the test member.4.1.4 Provide a re
13、lease mechanism that does not impart rotational or side-wise forces to the test package.If drop leaves are used,the apparatus shall provide a spring or other mechanism so that the leaves do not interfere with a free,unobstructed fall.4.1.5 Provide a rigid and level dropping surface that is integral
14、with a mass that shall be at least 50 times the weight of the dropping container.Neither the depth nor width of the mass shall be less than half the length.The dropping surface,firmly anchored to the mass,shall be a steel plate not less than 1/2 in.(13 mm)thick.4.1.6 A test unit for calibration purp
15、oses should be constructed.It shall be of the same general size and mass as maximum size and mass packages to be tested,and shall be dropped from heights in the expected range.The center or gravity of the unit shall be at its geometric center.When this unit is dropped,it must strike the impact surfa
16、ce within the specified limits.Compliance with the specifications may conveniently be determined with a camera.4.1.7 For very large packages it may be necessary to use a hoist,sling,and tripping devices or solenoid operated drop test mechanism and suspension devices shown in Figs.A I-A4 of Method D 997.4.2 Conditioning Apparatus-Adequate facilities shall be provided for conditioning test specimens at proper humidity and temperature prior to test in accordance with the specifi-cations covering th
