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 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 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 the standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.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 PalletsF1667 Specification for Driven Fasteners:Nails,Spikes,andStaplesIEEE/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 National Institute of Standards and Technology(NIST)PS1-95 Construction and Industrial Plywood41This 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 April 1,2011.Published April 2011.Originallyapproved in 1998.Last previous edition approved in 2005 as D6255/D6255M 05.DOI:10.1520/D6255_D6255M-05R11.2For 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.3Available from the Federal Supply Service Bureau,Specification Section,Suite8100,480 LEnfant Plaza,SW,Washington,DC 20408.4Available from National Institute of Standards and Technology(NIST),100Bureau Dr.,Stop 3460,Gaithersburg,MD 20899-3460.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.4 American Society of Mechanical Engineers(ASME)Standards:B18.2.1 Square and Hex Bolts and Screws(Inch Series)5B18.2.2 Square and Hex Nuts(Inch Series)5B18.2.3.5M Metric Hex Bolts5B18.2.4.1M Metric Hex Nuts,Style 15B18.2.4.2M Metric Hex Nuts,Style 25B18.5 Round Head Bolts(Inch Series)5B18.5.2.2M Metric Round Head Square Neck Bolts52.5 Hardwood Plywood and Veneer Association:HPVA HP-1-1994 Hardwood and Decorative Plywood62.6 National Motor Freight Traffc Association:National Motor Freight Classification72.7 U
