Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.

6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1 Intended use. Wood, wirebound, ammunition packing boxes covered by this specification are intended for shipment of ammunition, components, bombs accessories, rockets grenades, pyrotechnics, mines, jatos, guided missiles, demolition materials, special weapons components, and cartridge activated devices.

6.1.1 Grade A boxes are preservative and heat treated boxes for unrestricted overseas shipment or long term storage and handling of ammunition or explosive ammunition components.

6.1.2 Grade B boxes are heat treated non-preservative treated boxes for overseas shipment and short term storage and handling of ammunition or explosive ammunition components.

6.1.3 Grade C boxes are boxes without preservative or heat treatment. For interplant shipment and for storage and handling under controlled conditions of ammunition or explosive ammunition or explosive ammunition components, for domestic shipment only.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a. Title, number and date of this specification and all reference documentation cited in this specification (see 2.2.1). Note, reference documents will be those current at the time of solicitation or contract.

b. Requirements for submission of first article sample (if applicable).

c. Type, class and grade of box according to the title and number specified in this specification and applicable drawing.

d. Inside dimension in inches to the nearest 1/16 inch in order of length, by width and by depth.

e. Net weight of intended contents unless referenced on applicable drawing.

f. Requirements for acceptance inspection equipment designs (see 6.7).

6.3. Definitions.

6.3.1 Decay. Decay is disintegration of wood due to action of fungi. In the shop, decay can be best detected and differentiated from harmless stains and discoloration by use of the pick test. The pick test is performed with a knife or chisel by lifting some of the grain fibers in suspicious-looking areas. If the material is punky or more brash (breaks without splintering) than healthy wood of the same species, it is probably decayed. Suspicious areas are usually abnormally brown, bleached looking or mottled and indicated by the absence of luster that is present in normal wood.

6.3.2 Wane. Wane is bark or de-barked areas which may appear at the edge of the board.

6.4 Repair loops. Wire loops may be repaired as shown in Figure 10 and 10A if they are broken in service.

6.5 Assembly and closure. Maximum performance will not be obtained from boxes made in accordance with this specification unless they are correctly assembled and closed. The correct methods are illustrated in Figures 8A and 9. If other tools than the Sallee Closer are used, it should be determined that the closure obtained is similar in all respects, i.e., tightness of wire, foldover of loops, radius of bends of the wire.

6.6 Other fastenings. One type of fastener that has been found satisfactory is formed by a machine from a roll of knurled wire. The machine cuts the wire to the desired length, drives it through the pieces to be fastened, and makes a clinch and small head. In most instances, it will be found necessary to use 1-1/2 times as many of these fasteners as nails to be equivalent to the requirements of 3.13.1.

6.7 Submission of contractor inspection designs for approval. Contractor should submit copies of designs as required to:Commander,US Army ARDEC,ATTN: RDAR-EIQ-M, Picatinny, NJ, 07806-5000.

6.8 Submission of test methods for approval. Submit copies of test methods for approval to:

Commander, US Army ARDEC, ATTN: RDAR-EIQ-M, Picatinny, NJ, 07806-5000. These methods should include but not be limited to the accuracy and precision of the method, test data demonstrating the accuracy and precision and drawings of any special equipment required.

6.9 Heat treatment. The box manufacturer should be affiliated with an inspection agency accredited by the United States Department of Agriculture.

6.10 Deleted.

6.11 Submission of safety, health and environmental data. Submission of all available safety, health and environmental data such as Hazard Data Sheets and OSHA Safety Data Sheet is required. Of specific interest is the acute, subchronic and chronic toxicity data. Also submission of special safety, health and environmental information (apparatus and procedures) to be used throughout the treated box duty life and disposal is required.

6.12 Rope breaking force test method. The following should be used to determine the breaking force of a rope.

6.12.1 Apparatus.

a. Tensile testing machine meeting the following requirements:

a.1 The rate of travel of the pulling cross head during the breaking force test may be such that, after precycling the rope as described in 6.12.2.2, the rope is loaded to 20% of its estimated breaking force in not less than 20 seconds nor more than 200 seconds. The rate of travel of the pulling head may be adjusted during the precycling to achieve this rate.

a.2 The stroke and bed length of the testing machine may be long enough to extend the rope specimen to rupture in one continuous pull without interruption. With prior agreement of the purchaser and supplier, the splice procedure and splice eye size may be modified, if this will allow the test machine to accommodate the prescribed length of rope between splices.

a.3 The holding and pulling ends of the testing machine should have pins or posts whose diameters are no less than one and one half times the diameter of the rope being tested when using eye splice terminations.

a.4 The stroke of the testing machine (the total distance the cross head will move) must be long enough to extend the rope specimen to rupture in one continuous pull.

a.5 The testing machine should be equipped with a force indicating device such as a dial, digital read-out, or digital recorder; so that the maximum force required to rupture the specimen will remain on the indicator.

a.6 The testing machine should be calibrated at least once a year.

b. Fids of appropriate design and size to aid in eye splicing of the rope specimen.

6.12.2 Procedure.

a. The length of undisturbed rope between the splices or other terminations may be a minimum of

1500 millimeters (5 feet) for ropes up to 125 millimeters (5 inches) circumference and a minimum of at least 12 times the rope circumference for larger ropes.

a.1 For splicable ropes, the test specimens should be terminated with splices. For three-strand laid ropes, the minimum number of tucks for each splice should of four full tucks, one 2/3 tuck and one 1/3 tuck. For eight –strand plaited ropes, the minimum number of tucks for each splice should consist of two double and two single tucks. For braided ropes and any special rope constructions, consult with the rope manufacturer or the Cordage Institute for the necessary splicing instructions. Note: poor splicing can result in poor test results which do not reflect the actual breaking force of the rope. It is essential that the person preparing the specimen for test be trained properly and be experienced in the art of splicing rope so that the splicing is done properly and with good workmanship.

a.2 The inside length of each eye splice, measured with the insides of the eyes in contact, should be at least twice the pin diameter around which the eye will be placed on the test machine. The results of a rope break which occurs in the tucked portion of the rope specimen may be disregarded and another rope tested.

a.3 If agreed to in advance, blocks, clamps, grips or any other suitable means may be used in the above procedure instead of eye splices and pins to hold the test specimen while subjecting the rope to the test break. If a dispute arises concerning the test results using blocks, grips or any other holding mechanism, make the test with eye spliced rope.

b.1 Cycle the rope ten times to 20% of the estimated breaking force. During this precycling, the rate of travel of the testing machine moving cross head may be adjusted to achieve the required rate of travel prescribed in 6.12.1.1.1.

b.2 At the beginning of cycling, during the tenth cycle, after the tenth cycle and after the 30 minutes waiting period, measure the elongation and extension distances.

b.3 Increase the force in the rope until it breaks, at the rate of moving cross head travel prescribed in 6.12.1.1.1. Record the force at which the rope breaks and the maximum force applied to the rope, if higher than this breaking force.

b.4 Calculate the non-elastic elongation, residual elongation, recoverable elongation, total elongation, working elongation, and extension all to the nearest 0.1%.

6.12.3 Report. Report the following information:

a. State that the break test was made as directed. Describe the rope tested and the method of sampling used.

b. The specific method used for holding the specimen in the testing machine, the type of straining mechanism used and the rate of travel of the cross head.

c. The purchase order or contract number.

d. The number of cycles, applied load, elongations and extensions.

e. The breaking force of the specimen in kilonewtons or pound force.

f. The ambient temperature and per cent relative humidity prevalent during testing
