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 desiratle 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.

This standard is bounds o that any category and group can be removed and replaced with revised issues of that category and group.I t is intended that changes, when required, will be made to individual categories and groups only, rather than issue a complete revision of the standard. Changes will be issued as notices and will be numbered consecutively.

This standard includes a list of categories and groups with the latest date of issue for each category and group. When category and group is revised the list of categories and groups will also be revised and will be forwarded for insertion in the users copy of the standard.

This standard shall be maintained with all superseded categories and groups and list of categories and groups intact to assure that when users are applying the standard to requirements which may predate current category and group issues, the applicable issues will be available.
