The question

After a successful initial verification test on a repaired R-123 chiller that was not evacuated, how soon must the follow-up verification test be done?

• AWithin 30 days
• BWithin 10 daysCorrect answer
• CWithin 24 hours
• DWithin 12 months

Why “Within 10 days” is correct

40 CFR 82.157(e)(2) requires a follow-up verification test within 10 days of the successful initial test. If the appliance was evacuated for the repair, the 10 days run from when it reaches normal operating conditions.

Why the other answers are wrong

• Within 30 days — 30 days is the repair deadline, not the follow-up test window.
• Within 24 hours — The rule allows 10 days, not one day.
• Within 12 months — 12 months relates to presuming leaks repaired, not to follow-up testing.
