4、e Notice: Corrected values in Section 6.0 table for high boiling impurities; editorial changes. 1.0 SCOPE This specification covers the Companys requirements for fluorocarbon refrigerant for initial filling or recharging of refrigerant systems. These refrigerants will be: dichlorodifluoromethane, CF
5、C-12 (R-12), and 1,1,1,2 - tetrafluoroethane, HFC-134a (R-134a), as defined by the American Society of Heating, Refrigerating, and Air Conditioning Engineers in ANSI/ASHRAE 34-1992. 2.0 INTRODUCTION Federal Legislation (CFR 40-82) has mandated that the manufacture of chlorofluorocarbon refrigerants
6、(CFCs) in automotive air conditioning systems be halted. The use of the environmentally acceptable HFC-134a (R-134a) refrigerant was initiated in Navistar production facilities in January 1993. Further use of the CFC-12 (R-12) refrigerant is restricted to field service applications in product produc
7、ed prior to January 1993. The use of all other ozone depleting chemicals in International products is restricted. 2.1 Restricted Chemical Substances Effective January 1, 2007, all product supplied to the requirements of this specification must comply with the requirements of the CEMS B-50 specificat
