1、Designation: D 6039/D 6039M 02Standard Specification forCrates, Wood, Open and Covered1This standard is issued under the fixed designation D 6039/D 6039M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision. A

2、 number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers five types and two styles

3、ofopen and one type, and one style of covered wood cratesdesigned for net loads not exceeding 4000 lb 1814 kg. Opencrates are suitable for shipment of items, which are not readilysusceptible to damage from outside forces, and which requireonly limited protection against the elements.1.2 If environme

4、ntal protection is necessary, use of a shroudor a covered crate should be considered. With the exception ofType III, Style B crates, the crates included in this specificationare for use in domestic and overseas shipment of net loads notover 4000 lb 1814 kg. Use shall be confined to items fallingwith

5、in the dimensions and weight limitations of the types andgrades specified in Table 1.1.3 In general, Style A crates have heavier components andare to withstand rather severe handling and multiple shipments(heavy-duty), while Style B crates should be confined tohandling and shipping that impose only

6、light to moderatehazards on the container (light-duty). Types I, IV, and V cratesare general purpose types; Type II crates are designed for itemssuch as ladders, tubing, extrusions, or wallboard which do notrequire blocking, bracing, or cushioning; and Type III, Style Bcrates are designed for such s

7、elf-supporting material as chan-nels, angles, or other structural members where the containerserves only as a means for more convenient stacking andhandling.1.4 The values stated in either inch-pound or SI units shallbe regarded separately as standard. The values stated in eachsystem may not be exac

8、t equivalents; therefore, each systemmust be used independently of the other, without combiningvalues in any way.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 sa

9、fety and health practices and determine the applica-bility of regulatory limitations prior to use.1.6 If the use of other construction methods or techniques isacceptable and permitted (see 5.1.13), the resulting packagingsystems shall be of equal or better performance than wouldresult from the use o

10、f these specified materials and procedures.The appropriate distribution cycle specified in Practice D 4169can be used to develop comparative procedures and criteria.2.
