MIL-DTL-2427 Box, Ammunition Packing: Wood, NailedThis specification covers three types and nine classes of basic box designs having two exterior vertical cleats on each end as shown in figure 1. Also, it covers the closing and strapping requirements for filled boxes \(see Appendix A\), and prescribe the criteria to be utilized to determine the serviceability of Government furnished boxes \(see Appendix B\). The box may or may not have hinge and hasp hardware, rope handles and double end construction.

4.3.4 Inspection equipment. The government reserves the right to inspect the

contractor's equipment and determine that he has available and utilizes correctly,

measuring and test equipment of the required accuracy and precision and that the

instruments are of the proper type and range to make measurements of the required

accuracy. Commercial inspection equipment shall be employed where applicable for all

tests and examinations specified in 4.3 and 4.4. The contractor is responsible for assuring

that proper calibration procedures are followed. Government approval of all inspection

equipment is required prior to its use for acceptance purposes (see 6.9).

4.3.4.1 Certification. Certification shall be provided to ensure preservative

treatment used is in full conformance to the requirements of 3.10. Certification shall be

provided to ensure wood material used is in full conformance with the requirements of

3.2.1

4.4 Methods of inspection. (see 6.10).

4.4.1 Load test of rope handles. The box shall be packed with any suitable

material until its gross weight is twice as great as its gross weight packed with the item

for which it was intended. If the resulting weight of the packed box is 250 pounds (lbs.)

or less, 4.4.1.1 shall be followed. If the resulting weight is greater than 250 lbs. and not

greater than 500 lbs., 4.4.1.2 shall be followed.

4.4.1.1 Rope handles load test (Boxes that weigh 250 lbs. or less). The box shall

suspend freely for one minute, minimum, from each rope handle in turn. Test to be

performed at max weight. In the event that one or both handles fail the requirement, the

box shall be classified defective.

4.4.1.2 Rope handle load test (Boxes that weigh between 250 lbs. and 500 lbs.

maximum). The box shall suspend freely for one minute, minimum, from both rope

handles (at once). Test to be performed at max weight. In the event that one or both

handles fail the requirement, the box shall be classed defective.

4.4.2 Moisture content. The ammunition box shall be tested in accordance with

ASTM-D4442 except that three readings (e.g., side and end cleat) shall be taken on each

box selected.

4.4.3 Rope weight. To measure length of polyethylene or polypropylene rope for

the purpose of determining rope weight per foot, the sample of rope submitted shall be

stretched with a load equal to 200 pounds multiplied by the diameter in inches squared.

While the rope is under load, a 30 foot length shall be marked off, length measurement

determined under load. Weight in pounds per foot shall be computed.

4.4.4 Rope breaking strength. The breaking strength of the five samples of

polyethylene or polypropylene rope shall be determined in accordance with CI 1500-02.

The average breaking strength shall be computed.
