Standard Specification for Wood-Cleated Shipping Boxes and Skidded, Load-Bearing Bases

ABSTRACT
This specification covers the fabrication of wood-cleated shipping boxes with skidded. load-bearing bases designed for nonregulated domestic and overseas shipment of loads under a specified weight limit. Box performance under all atmospheres, handling, shipping, and storage conditions is not discussed here. The boxes are classified into two types according to base material, two classes according to shipment destination, two styles, and two treatments. It is recommended that the boxes be made from recycled materials, lumber, fiberboard, fasteners, and base components that meet the requirements of this specification. Each box side and joint should be assembled according to the recommended procedures.
SCOPE
1.1 This specification covers the fabrication of new wood-cleated boxes with skidded, load-bearing bases. Boxes covered by this specification are designed for nonregulated domestic and overseas shipment of loads less than 2500 lb [1134 kg] and not greater than 16 ft [4877 mm] in length (see 9.1). Regulated commodities shipments may require better boxes than those specified herein (see 9.2).
1.2 The performance of wood-cleated boxes with skidded, load-bearing bases is dependent on their fabricated components; therefore, a variety of types, styles, and classes reflecting varied performance are specified. This specification, however, does not cover box performance under all atmosphere, handling, shipping and storage conditions.
1.3 If the use of other construction methods or techniques are acceptable and permitted (see 5.1.18), the resulting packaging systems shall be of equal or better performance than would result from the use of these specified materials and procedures. The appropriate distribution cycle specified in Practice D 4169 can be used to develop comparative procedures and criteria.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may 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 the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
