Abstract : This report details the scope of work and results obtained in a program to evaluate the performance characteristics of typical commercial elastomer coated fabrics used to fabricate inflatable boats, such as those currently cited in MIL-B- 53067 for 3-, 7-, and 15-person sizes. Comparison of the material test data with the criteria cited in the new combined specification indicates that conformance is attainable. Likewise, in-house evaluation of performance of seams constructed from the candidate fabrics was generally acceptable. It is concluded that MIL-B-53067, as drafted, is acceptable for procurement of pneumatic boats in the specified sizes.
