Index

Describes a method for the determination of the gross calorific value of a solid biofuel at constant volume and at the reference temperature 25 degrees C in a bomb calorimeter calibrated by combustion of certified benzoic acid.

This International Standard specifies a method for the determination of the absorbance at ultraviolet wavelengths of animal and vegetable fats and oils.
