Components of the top and bottom polar closures used in NEMO capsules 1,2, and 3. The structural integrity test was performed on the steel parts in conjunction with the structural integrity testing of the acrylic plastic cap- sule, as it was felt that only by testing the steel closures mounted in the acrylic plastic capsule (Figure F-4) would it be possible to obtain a realistic evaluation for both. STRUCTURAL INTEGRITY CONTROL The overall structural integrity of the acrylic plastic capsules was established by a hydrostatic proof test. The acrylic plastic capsules were mated with their steel polar plates, instrumented with electric resistance strain gages, and subjected to a 4-hour hydrostatic loading under 500-psi external pressure. If no water was found in the interior of the capsule and the strains measured at the equator matched those on prototype capsule 0 under identical loading (Figure F-5), the performance of the capsule was acceptable. Since none of the three capsules leaked and the strains on the equator matched those recorded previously on capsule 0, capsules 1, 2, and 3 211
