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 which must be met or exceeded.

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

This standard is bound so that any category and group can be removed and replaced with revised issues of that category. It 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" with the latest date of issue for each category. When a category is revised the "List of categories" will also revised and will be forwarded for insertion in the users copy of the standard.

This standard shall be maintained with all superseded categories and "List of categories" intact to assure that when users are applying the standard to requirements which may predate current category issues, the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