If a sample is hazy what do you do?
Let it settle for 30 mins, if not bright then water bath (120 +/- 5 degrees x mins), if sat proceed to bright test, otherwise it fails clear portion.
Describe the transparency test?
With a sample at 120+/-5 degrees, hold the sample up to a light source with a standard print document behind (pms card). if readable, it passes
Describe a visible particle test
Let the bottle stand for 10mins, then flip it on its side for ten minutes. Then look for unbroken line or any particle greater that 1/8th of an inch
How is a BS&W performed for L/O?
(1) Obtain two clean, dry centrifuge tubes and set the tubes in the test tube rack. Shake the oil sample bottle
well. Fill each centrifuge tube with 50 ml of well-shaken sample.
S9086-H7-STM-010
262-5-5
(2) Set the tubes in the test tube rack and fill each tube to the 100 ml mark with PD-680 type II or BIOTEK
Hi-Solv. Cover a cork with a thin plastic film (such as cellophane) so that it can be reused. Rubber stoppers can also be used. Tightly seal each tube and shake for 30 seconds to ensure adequate mixing of the
oil and solvent.
(3) Place the centrifuge tubes securely on opposite sides in the centrifuge. Set the timer for 31 minutes
(allowing 1 minute for the centrifuge to come up to speed and 30 minutes for test time). Whirl at 1500
(±50) RPM. If centrifuge does not have RPM display, confirm actual RPM annually using a tachometer.
(4) Remove the tubes and obtain the percent BS&W by adding the combined water/sediment readings of the
two tubes.
(a) SATISFACTORY:
1. Sediment less than 0.1% AND
2. Combined BS &W less than 0.2%.
(b) WARNING CONDITION:
1. Sediment less than 0.1% AND
2. Combined BS&W from 0.2% to less than 0.4%.
(c) UNSATISFACTORY:
1. Sediment 0.1% and higher; OR
2. Combined BS&W equal to or greater than 0.4%.
(5) At the end of the test, dispose of oily waste in the contaminated oily waste holding tank.
(6) Clean the centrifuge tubes with solvent.
(7) Table 262-5-2 provides the actions that shall be taken for WARNING or UNSATISFACTORY conditions.

Missing tag discovered during an audit?
Stop all work
Indicate tag missing (block 20b)”Missing-replaced”
AO fill in block 21 and initial block 22
generate a missing tag using the same tag number, then hang the replacement tag
Damaged Tag?
Evaluate the tag and whether it needs replacing. stop work if needed
In block 19 indicate the tag was damaged “Damaged-replaced”
generate and post replacement tag using same tag number.
After, clear the damaged tag (blocks 20a and 20b)
