ASTM D6039 / D6039M - 11 Standard Specification for Open and Covered Wood Crates

0

Source: ASTM International

This specification covers five types and two styles of open and one type, and one style of covered wood crates designed for net loads not exceeding 4000 lb [1814 kg]. Open crates are suitable for shipment of items, which are not readily susceptible to damage from outside forces, and which require only limited protection against the elements. In general, style A crates have heavier components and are to withstand rather severe handling and multiple shipments (heavy-duty), while style B crates should be confined to handling and shipping that impose only light to moderate hazards on the container (light-duty). Types I, IV, and V crates are general purpose types; type II crates are designed for items such as ladders, tubing, extrusions, or wallboard which do not require blocking, bracing, or cushioning; and type III, style B crates are designed for such self-supporting material as channels, angles, or other structural members where the container serves only as a means for more convenient stacking and handling. The construction and assembly method for open and covered wood crates are presented in details. A crate shall be completely assembled to ensure achievement of a container which can be properly and easily assembled which is square, and is of the proper size. Evaluate the clarity and logic of the assembly instructions.

This abstract is a brief summary of the referenced standard.

1. Scope

1.1 This specification covers five types and two styles of open and one type, and one style of covered wood crates designed for net loads not exceeding 4000 lb [1814 kg]. Open crates are suitable for shipment of items, which are not readily susceptible to damage from outside forces, and which require only limited protection against the elements.

1.2 If environmental protection is necessary, use of a shroud or a covered crate should be considered. With the exception of Type III, Style B crates, the crates included in this specification are for use in domestic and overseas shipment of net loads not over 4000 lb [1814 kg]. Use shall be confined to items falling within the dimensions and weight limitations of the types and grades specified in Table 1.

1.3 In general, Style A crates have heavier components and are to withstand rather severe handling and multiple shipments (heavy-duty), while Style B crates should be confined to handling and shipping that impose only light to moderate hazards on the container (light-duty). Types I, IV, and V crates are general purpose types; Type II crates are designed for items such as ladders, tubing, extrusions, or wallboard which do not require blocking, bracing, or cushioning; and Type III, Style B crates are designed for such self-supporting material as channels, angles, or other structural members where the container serves only as a means for more convenient stacking and handling.

1.4 If the use of other construction methods or techniques is acceptable and permitted (see 5.1.13), 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.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.6 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.
