The MXU-695/B ballonet consists of a welded tube assembly and a CCU-l3/B impulse cartridge. equally spaced longitudinal depressions each approximately 50 inches long. The depressions are packed
13、with lay-flat plastic tubes filled with a mixture of sulfur and silicon dioxide. The CCU-13/B impulse . cartridge contains the propellant and ignitor for expanding the depres- sions from the tubing during operation of the weapon. The tube contains three 3.2 Characteristics. 3.2.1 Performance. 3.2.1.
14、1 Solids load. There shall be no visual evidence of white and yell.ow separation areas or lumps, and the angle of repose shall be not greater than 45 degrees (deg). 3.2.1.2 Lay-flat tubing seal. There shall be no evidence of leaks from the lay-flat tbing surface or adhesive interface (see 4.4.2). 3.
15、2.1.3 Adhesive system peel strength. The peel strength shall be not less than 75 ounces (see 4.4.3). c 3 .

Unless otherwise specified in the con- tract or purchase order (see 6.2.1), the number of sampl
29、e units to be submitted for preproduction testing shall be 10 ballonets, and one waterproof container of excess blend (10-pound minimum) prepsred for each lot of sulfur used in the 10 sample ballonet units. The prepro- duction sample shall be manufactured using the same methods, materials, processes
30、, and procedures proposed for production. Any production prior to acceptance of the preproduction sample shall be at the risk of the contractor. 3.4.2 Preproduction verification. At the discretion of the procuring activity.(see 6.2.1), preproduction verification shall be repeated under any:of the fo
31、llowing conditions: a. The manufacturer has modified his product (such as a change of raw materials, the process, production procedures, or methods). It shall be the responsibility of the contractor to notify the procuring activity prior to the incorporation of any such changes, and to provide quant
32、itative evidence of the effect of.such changes on the performance or character- istics of the product.

Where there is evidence that the quality of the product has not been maintained, this evidence may be in the form of accumulated failure reports of the product, of system fail- ures attributable to the product, or failure of the product to pass any of the tests for
34、production lot acceptance that may be conducted by or for the procuring activity. c. Applicable documents have been amended or revised suffi- ciently so that continued validity of the previous prepro- duction testing is questionable. d.

Failure of the materials to meet any of the requirem
42、ents shall be cause for rejection of the lot of material and all ballonets loaded with that lot of material. Any failure attributable to the ballonets shall cause rejection of the entire preproduction sample and preproduction lot. 4.1.2.2 ombined testing. Preproduction inspections of the ballonet an
