Moreover, this document provides additional guidance to the entire ISO 14404 series for the following topics.
a) Evaluation of exported slags
b) Evaluation of by-product gas
c) Evaluation of stock
d) Selection of calorific values and emission factors for electricity and fuel
Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.
While the use of the calculation result is outside the scope of this document, appropriate applications and inappropriate application are recommended in Annex B.
