Key for oil types (Ref. 4)
4 = ITOPF category Group IV Sg> 0.95 or PP > 30 degrees C
3 = ITOPF category Group III Sg 0.85-0.95 e.g. medium crude
2 = ITOPF category Group II Sg 0.8-0.85 e.g. light crude, gas oils
1 = ITOPF category Group I Sg < 0.8 e.g. Kerosenes / Gasolines
NB. When ambient temperatures are at or below the oil's pour point then group
2 oils behave as group 3 or 4 and response measures should be altered
accordingly.
