Designation:D6255/D6255M18Standard 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 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.Scope*1.1 This specification covers the material 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 performance 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 construction 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 comparative 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.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 this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2A109/A109M Specification for Steel,Strip,Carbon(0.25Maximum Percent),Cold-RolledA123/A123M Specification for Zinc(Hot-Dip Galvanized)Coatings on Iron and Steel ProductsA924/A924M Specification for General Requirements forSteel Sheet,Metallic-Coated by the Hot-Dip ProcessB209 Specification for Aluminum and Aluminum-AlloySheet and PlateB633 Specification for Electrodeposited Coatings of Zinc onIron and SteelD996 Terminology of Packaging and Distribution Environ-mentsD1990 Practice for Establishing Allowable Properties forVisually-Graded Dimension Lumber from In-Grade Testsof Full-Size SpecimensD3951 Practice for Commercial PackagingD3953 Specification for Strapping,Flat Steel and SealsD4169 Practice for Performance Testing of Shipping Con-tainers and SystemsD4727/D4727M Specification for Corrugated and Solid Fi-berboard Sheet Stock(Container Grade)and Cut ShapesD6199 Practice for Quality of Wood Members of Containersand PalletsD6253 Practice for Treatment and/or Marking of WoodPackaging MaterialsF1667 Specification for Driven Fasteners:Nails,Spikes,andStaples1This specification is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.12 on ShippingContainers,Crates,Pallets,Skids and Related Structures.Current edition approved March 1,2018.Published April 2018.Originallyapproved in 1998.Last previous edition approved in 2011 as D6255/D6255M 05(2011).DOI:10.1520/D6255_D6255M-18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 IEEE/ASTM SI 10 Standard for Use of the InternationalSystem of Units(SI):The Modern Metric System2.2 Federal Specifications:TT-W-572 Wood Preservative:Water-Repellent32.3 APA The Engineered Wood Association:APA PS 1 Structural Plywood(with Typical APA T
