b If these two test methods yield different results, use the results from ASTM D1267.
c The test fuel must not yield a persistent oil ring when you add 0.3 ml of solvent residue mixture to a filter paper in 0.1 ml increments and examine it in daylight after two minutes.

Mass standards.
b Dynamometer, fuel mass scale, and DEF mass scale calibration weights.
Use dynamometer and mass scale calibration weights that are certified as NIST-traceable within 0.1% uncertainty.
Calibration weights may be certified by any calibration lab that maintains NISTtraceability.
369. Amend 1065.905 by revising paragraph f to read as follows:
