EPA Section 608 Universal Certification ExamType III (Low-Pressure Appliances)Hard
A low-pressure chiller has a significant leak. The EPA defines a 'significant leak' for comfort cooling low-pressure appliances as a leak rate exceeding what percentage of the total charge per year?
- A10%
- B15%
- C5%
- D20%
Show answer & explanationAnswer & explanation
Correct answer: A. 10%
For comfort cooling low-pressure appliances, the EPA defines a 'significant leak' as a leak rate exceeding 10% of the total charge per year. This threshold triggers mandatory leak repair requirements.
Why the other options are wrong
- B. 15% is the threshold for commercial refrigeration appliances (high-pressure), not low-pressure comfort cooling.
- C. 5% is the threshold for industrial process refrigeration (IPR) if a lower standard is set by the owner, not comfort cooling.
- D. 20% is not a recognized EPA leak rate threshold for any appliance type.
Low-Pressure Significant Leak Threshold (Comfort Cooling)
For low-pressure comfort cooling appliances, a 'significant leak' is defined by the EPA as a leak rate exceeding 10% of the total refrigerant charge per year.
- Applies to comfort cooling systems.
- Low-pressure appliances.
- Threshold is 10% annually.
- Triggers leak repair requirements.
Memory trick: For comfort 'Cooling', Ten Percent is too 'Loose-ing'.
