ASTM F1155
Scope
1.1 This practice is intended as a guide to shipbuilders, shipowners, and design agents for use in the preparation of piping system material schedules for
commercial ship design and construction.
1.2 The materials and limitations listed in Tables 1-28 meet the minimum
requirements of the U.S. Coast Guard and the American Bureau of Shipping and, except for titanium, should be considered to be the minimum acceptable materials in regard to material, design, and
testing. This document is not intended to limit the selection of material strictly to those listed. Other equal or superior materials may be used provided that they are acceptable to the
regulatory bodies and classification societies.
Note 1: Titanium has been added as its use in fresh and sea water systems is becoming more
common.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on
Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
