1、Designation:D6653/D6653M13Standard Test Methods forDetermining the Effects of High Altitude on PackagingSystems by Vacuum Method1This standard is issued under the fixed designation D6653/D6653M;the number immediately following the designation indicates theyear of original adoption or,in the case of
2、revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods determine the effects of pressuredifferential when packaged products are transporte
3、d via certainmodes of transport,such as feeder aircraft or ground over highmountain passes.The results of these tests are intended to beused for qualitative purposes.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system
4、may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibilit
