Green coffee — Procedure for calibration of moisture meters — Routine method
This International Standard specifies a procedure for adjustment and subsequent calibration of moisture meters
for green coffee beans with reference samples (RSs).
The RSs are green coffee beans of various moisture contents, determined by a standard method (ISO 6673).
NOTE This method of determining the loss in mass can be considered, by convention, as a method for determining
the water content…
