1) Neutralization # or Acidity – ASTM D974

2) Interfacial Tension – ASTM D971

3) Dielectric Breakdown Voltage – ASTM D877 or D1816

4) Color – ASTM D1500

5) Relative Density or Specific Gravity – ASTM D1298

6) Visual Appearance – ASTM D1524

7) Sediment Assessment – ASTM D1524

8) Oxidation Inhibitor Content – ASTM D2668
