Refrigerant Charge Determination Test Method
The purpose of this document is to establish guidelines for determining the critical refrigerant charge for off-road, self-propelled work machines, general purpose industrial, agricultural, forestry, and specialized mining machinery. It will develop a minimum to maximum refrigerant charge range in which the HVAC system can maintain proper operation. Operating conditions and characteristics of the equipment will influence the optimum charge. Since these conditions and characteristics vary greatly from one application to another, careful consideration should be taken to determine the optimum refrigerant charge for the HVAC system.
