scope:

This standard covers the requirements governing the procedure for chemical cleaning of main propulsion boilers of ferrous construction. Auxiliary (hotel load) boilers or waste heat boilers of ferrous or silicon - bronze (Herculay) construction can also be chemically cleaned using this standard. Differences in the configuration and volume of auxiliary and waste hear boilers must be considered when this standard is used to clean nonpropulsion boilers. The procedure may be used by ship's force, Naval shipyards, and private contractors.
