Documentation
Definition
The heating value class defines whether the heating value entered into the system is a superior or inferior heating value. In addition, it specifies whether the gas is dry or wet. A gas is defined to be dry if it does not contain more than 50 ppm (molar) water in the vapor phase.
Superior calorific value: The energy released as heat energy by the complete combustion in air of a defined quantity of gas, in such a manner that the pressure p_c at which the reaction takes place remains constant, and all the products of combustion are returned to the same specified temperature T_c as that of the reactants, all of these products being in the gaseous state except for water formed by combustion, which is condensed to the liquid state at T_c. If the water is also returned to the gaseous state, the calorific value is labeled Inferior. See Draft International Standard ISO/DIS 14532 for additional details.
The test heating value class specifies the test heating value.
The base heating value class is defined in the conversion group and specifies the base heating value. If no test heating value class is entered as a test heating value class during the conversion process, the base heating value class is used as a default.
The material heating value class is used if an energy quantity is used as either a target or transaction quantity and the unit of measure of this energy quantity does not specify a heating value class.
The standard delivered QCI (Quantity Conversion Interface) does not perform a conversion form inferior to superior heating values or vice versa. It takes into account the superior/inferior character when determining the base heating value. The QCI (Quantity Conversion Interface) checks that both the test heating value class and base heating value class are either superior or inferior. If not, an error message is issued. This message can be customized to appear as a warning or information message, so that in customer specific conversion routines a conversion from superior to inferior or vice versa can be performed.
