Test Procedure for Determining Refrigerant Emissions from Mobile Air Conditioning Systems
J2763
This SAE Standard covers the mini-shed testing methodology to measure the rate of refrigerant loss from an automotive air conditioning (A/C) system. This SAE procedure encompasses both front and rear air conditioning systems utilizing refrigerants operating under sub-critical conditions. The SAE procedure will cover multiple refrigerants to emission testing and is utilized for evaluating air condtioning systems. Heat pump systems can be evaluated, however, will have different usage and mission profiles.
Rationale: This document covers a method for meassuring refrigerant system emission and is being updated for the addition of evaluating multiple refgierants, adding zero-span gas calicbtration for more accurate meassurements, and refinements of the the equations in deriving the mass emission amounts. The intent of this Standard is to insure proper measurement of refrigerant emission in an A/C system.
