NOTES:
1/
No limiting requirements. Test values shall be recorded in the test report.
2/
Prior to the test, the fluid shall be water washed as follows: 300 grams of the fluid to be tested shall be stirred
with 50 grams of water for 30 minutes at 90 °C (194 °F) using the beaker and stirrer as specified in
ASTM D665. After 30 minutes stirring, the mixture shall be transferred to a separatory funnel and left to
separate; then the water layer shall be drawn off and the fluid submitted to the salt water corrosion test.
3/
Option A shall not be used. A ring of bubbles around the edge of the graduate shall be considered complete
collapse or zero milliliters.
4/
Distilled water and stirring temperature of 54 °C (130 °F) shall be used. Discrete water droplets entrained in
the oil layer and clinging to the wall of the cylinder may be added to the water layer volume at the rate of 0.1
milliliter per droplet. The results shall be reported using the format of oil layer/water layer/emulsions layer
(time in minutes). There is no requirement for water layer. The emulsion limit applies to any of the three
types of emulsions defined in the test method. If more than one emulsion type is present, the three milliliter
maximum limit applies to the combined volume of the different emulsion types.
5/
Determine total iron content using the procedure and calculations described in sections 12 and 13 of
ASTM D4310, except substitute iron in place of copper where appropriate.
6/
Test sample in accordance with ASTM D4898 using 0.8 micrometer pore diameter membrane filters.
7/
If ASTM D524 is used to determine carbon residue, the reported result must be converted from Ramsbottom
to Conradson using the correlation data within ASTM D189 or D524.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a.
Qualification inspection (see 4.2).
b.
Conformance inspection (see 4.3).
4.2 Qualification inspection. Qualification inspection shall be performed at a Government-approved laboratory
and conducted as specified in 4.4 and Table I. A minimum sample size of 10 gallons is required for qualification
testing.
4.2.1 Requalification. Unless otherwise approved by NAVSEA, requalification shall consist of the tests
4.3 Conformance inspection. The conformance inspection shall consist of the tests specified in 4.4.6 and Table
I, except the 1000-hour oxidation test and compatibility test shall not be required. In addition, each lot of filled
containers shall be examined as specified in 4.4.
