Where can water contamination tests for fuel oil storage and service tanks be found?

The correct answer is NSTM 541, which specifically focuses on fuel and fuel systems management. It provides detailed information regarding the inspection and testing of fuel oil, including guidelines for water contamination tests in fuel oil storage and service tanks. Understanding the proper testing procedures for contamination helps ensure the integrity and quality of the fuel, which is essential for the efficient operation of machinery and engines.

NSTM 541 outlines methods for conducting these tests, the frequency of testing, and the significance of maintaining water-free fuel to prevent operational issues, contamination, and equipment damage. This makes it a critical reference for personnel responsible for managing fuel systems aboard naval vessels.
