.c.

At least once per 31 days by checking for and removing accumulated water from the fuel oil storage tanks; d.-

By sampling new fuel oil in accordance with ASTM-04057 prior to addition to storage tanks and:

1)

By verifying in accordance with the tests specified in 1

ASTM-0975-81 prior to addition to the storage tanks that the sample has:

a.

An API Gravity of within 0.3 degrees at 60*F, or a specific gravity of within 0.0016 at 60/60'F, when compared to the supplier's certificate, or an absolute specific gravity at 60/60'F of greater than or equal to-0.83 but.less than or equal to 0.89, or an API gravity of greater than or equal to 27 degrees but less than or equal to 39 degrees; b.

A kinematic viscosity at 40'C of greater than or equal to I

1.9 centistokes, but less than or equal to 4.1 centistokes

-(alternatively, Saybolt viscosity,' SUS at 100'F of greater than or equal to 32.6, but not less than or.cqual-to 40.1), if gravity was not determined by comparison with p

the supplier's certification;

This. test shall be-conducted in accordance with the manufacturer's:recommenda-tions regarding engine prelube and warmup procedures, and as applicable-regard-ing loading recommendations.
