46、nch Tips valve of the same design may be qualified by similarity. Qualification tests shall be conducted on at least two specimens of each size valve. Unless waived by NAVSEA, the two specimens shall be prepared to adverse dimensions in accordance with 4.3.1.1 through 4.3.1.3. (c) For those sizes se
47、lected for full qualification testing, the inspections shown in table III shall be satisfactorily accomplished, specified in 4.7.1, 4.7.2, 4.7.4.1 and 4.7.4.2 shall be satisfactorily accomplished.

49、m designed clearance permitted by the manufacturers drawings. For cases of sliding Farts where packing friction would influence the performance of the component, such as pistons operated by spring, the maximum packing friction anticipated shall be induced in the test specimen. In these cases, O-ring pack- ing glands shall be fabricated to provide maxinum design O-ring squeeze, inclu- ding the effect of adverse O-ring cross section toleran
