Scope

Adds zeotropic alternative refrigerants, excludes emerging supercritical refrigerants like CO2 (which require a new test standard), provides six test methods for determining refrigerant mass flow rates, permits the same test method for the primary and confirming tests under certain conditions, includes test methods that properly account for the effects of liquid refrigerant injection, and adds compressor-efficiency computations to the test requirements.
