Refrigerant Standard Revised

The standard establishes purity specifications and stipulates the associated testing methods for acceptability for fluorocarbon refrigerants for use in new and existing refrigeration and air-conditioning products. The standard also specifies acceptable contaminant levels for fluorocarbon refrigerants and lists acceptable test methods.
