Few notes...
NMMA FC-W has same requirements on ASTM D892 as API SN:
Sequence I, ml initial/ml after settling: 10 / 0
Sequence II, ml initial/ml after settling: 50 / 0
Sequence III, ml initial/ml after settling: 10 / 0
NMMA FC-W has lower requirements on ASTM D6082 as API SN:
Sequence IV, ml initial/ml after settling for 1 minute: 200 / 50 (NMMA)
Sequence IV, ml initial/ml after settling for 1 minute: 100 / 0 (API)
API CK-4 has higher requirements on ASTM D892 as API SN:
Sequence I, ml initial/ml after settling: 10 / 0
Sequence II, ml initial/ml after settling: 20 / 0
Sequence III, ml initial/ml after settling: 10 / 0
API CK-4 also has to meet COAT requirements:
