scope:

This standard covers requirements for basic piping system components on Navy surface ships. It is not the intention herein to include every conceivable component, valve, or fitting that might be used in the piping system of a surface ship. The requirements invoked herein are not desirable goals but are minimum acceptable standards.

This standard is broken down into basic service categories and groups. The notes contained in each individual category and group and prefaced with the category and group designation, apply only to that specific category and group. General requirements are also included to supplement the specific category and group notes. General requirements apply to all service categories and groups where the content of the requirement is applicable.
