1、Designation:D6255/D6255M05(Reapproved 2011)Standard Specification forSteel or Aluminum Slotted Angle Crates1This standard is issued under the fixed designation D6255/D6255M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of
2、last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers the material
3、 and fabrication ofnew reusable metal(slotted angle)crates intended for use ascontainers for domestic and overseas shipment of lightweightairframe components and lightweight bulky items,not exceed-ing 3000 lb 1361 kg for domestic or overseas air and surfaceshipments.1.2 Slotted angle crate performan
4、ce is dependent on itsfabricated components;therefore,a variety of types,classes,and styles reflecting varied performance are specified.Thisspecification,however,does not cover slotted angle crateperformance under all atmosphere,handling,shipping,andstorage conditions.1.3 If the use of other constru
5、ction methods or techniquesare acceptable and permitted(see 5.1.12),the resulting pack-aging systems shall be of equal or better performance thanwould result from the use of these specified materials andprocedures.The appropriate distribution cycle specified inPractice D4169 can be used to develop c
6、omparative proceduresand criteria.1.4 The values stated in either inch-pound or SI units are tobe regarded separately as standard.Within the text,the SI unitsare shown in brackets.The values stated in each system are notexact equivalents;therefore,each system must be used inde-pendently of the other
7、.Combining values from the two systemsmay result in nonconformance with the standard.See IEEE/ASTM SI 10 for conversion of units.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of the standard to establish app
