Which SAE standard covers recommended service procedures for the containment of HFC-134a (R-134a)?
A. SAE J639
B. SAE J2064
C. SAE J2211
D. SAE J2845
Answer (2)
The correct SAE standard for the containment of HFC-134a (R-134a) is SAE J2064. This standard provides detailed recommended service procedures specifically for this refrigerant. Understanding these practices is essential for safe and environmentally responsible automotive service.
;
The question pertains to the recommended service procedures for the containment of HFC-134a, also known as R-134a, which is a refrigerant commonly used in automotive air conditioning systems.
To address this, we need to determine which SAE (Society of Automotive Engineers) standard specifically relates to these procedures:
SAE J639 : Covers safety standards for refrigerants in systems, but not specifically containment.
SAE J2064 : Pertains to refrigerant hose, fittings, and related components.
SAE J2211 : This standard provides guidelines for the servicing and containment of refrigerants, including HFC-134a (R-134a). SAE J2211 establishes practices to prevent refrigerant emissions while servicing, thus directly addressing containment.
SAE J2845 : Describes technician training requirements but not containment.
Therefore, the correct answer is (C) SAE J2211 .
SAE J2211 plays a critical role by providing recommended service procedures for the containment of R-134a to reduce emissions and ensure safety during servicing operations. This standard is vital to maintaining compliance with environmental regulations and promoting the safe handling of refrigerants in automotive systems.
