4. Formula and requirementsImplemented formulaThis is an implementation of natural gas conversion groups which is based on:ISO 12213-3, Second edition 2006-11-15, “Calculation of compression factor – Part 3:Calculation using physical properties”.The formulas utilized by the conversion groups described in this document areimplemented within the SAP QCI and QuantityWare BCG 10A functions. Together theyallow conversions between different sets of standard (base) reference conditions.Although ISO 13443 defines a temperature value of 15 °C (288,15 K) and a pressurevalue of 101,325 kPa as standard reference conditions for measurements andcalculations for real dry gas (natural gases, natural-gas substitutes, similar fluids in thegaseous state), it is recognized that in certain circumstances it may be impracticable oreven forbidden to use these ISO standard reference conditions (e.g. forced by nationallegislation or contractual obligations). Thus, conversion formulas are provided in ISO13443 which enable values of properties (relating to any known other referenceconditions) to be converted to values for the ISO standard reference conditions.In addition to the formulas provided within ISO 13443, calculation formulas based onISO 6976:1995 (E) are utilized by the SAP QCI.QuantityWare offers a global conversion group template which can be used tovalidate the SAP QCI formulas (see document BCG 10A ISO QCIVALIDATION).The SGERG88 routines are implemented in QuantityWare functions - provided withinBCG 1.0A - that implement and connect the SGERG88 equation procedure via theprovided conversion groups to the SAP QCI; these formulae and implementationprocedures are based on ISO 6976:1995(E), ISO 13443 and ISO 12213-3, Secondedition 2006-11-15 (SGERG88 implementation procedure).ISO 12213-3 (SGERG-88 equation) 17-24
