R12/R134a Purity Setpoint:
Pass if single refrigerant, R12 or R134a, is detected in concentrations equal to or greater than 98% by weight.
Unknown Refrigerant Purity Setpoint:
In the presence of detected unknown refrigerant types R12 or R134a is considered pure if detected in concentrations equal to or
greater than 96% by weight.
Effect of Air Concentrations:
Air is not considered a contaminate and will be removed from the weight concentration determination of refrigerants. Air
concentrations will only be reported for blends of R12 and R134a refrigerants.
SAE J1771:
If the refrigerant being tested is identified as contaminated, any visual percentages displayed of CFC-12 (R-12) or HFC-134a (R-
134a) outside the design certified value is informational and may not be accurate. SAE J1771 Certification Note: This equipment
has not been designed certified for contaminate detection of R-124 or R-142B.
