D Exceeding 4200 but not exceeding 4940
E Exceeding 3360 but not exceeding 4200
F Exceeding 2400 but not exceeding 3360
G Exceeding 1300 but not exceeding 2400
The formula for caluclation of UHV shall be as follows:
UHV = 8900 - 138(A + M) where
A = Ash
M = Inherent Moisture in coal determined under standard
conditions of 60% RH & 40 Degree C basis
