This European standard DIN EN 13771-1 applies only to refrigerant compressors and specifies methods for performance testing. These methods provide sufficiently accurate results for the determination of the refrigerating capacity, power absorbed, refrigerant mass flow, isentropic efficiency and the coefficient of performance. This European Standard applies only to performance tests where the equipment for testing is available. Regarding the German collaboration, the responsible Working Committee is NA 044-00-14 AA "Kältemittel-Verdichter" ("Refrigerant compressors"), Spiegelausschuss zu CEN/TC 113 "Wärmepumpen und Luftkonditionierungsgeräte" (mirror committee to CEN/TC 113 "Heat pumps and air conditioning units") at DIN Standards Committee Refrigeration Technology (FNKä).
