Core (Universal)Question 33 of 24075% of test-takers answer this correctly

Under the Section 608 leak repair rules (40 CFR §82.157), the leak rate thresholds apply to appliances that normally contain how much refrigerant?

a.Any amount, regardless of charge
b.5 pounds or more
c.50 pounds or more
d.200 pounds or more

Explanation

The EPA 608 exam keys 50 pounds: 40 CFR §82.157 applies to appliances that normally contain 50 or more pounds of a class I or class II (ozone-depleting) refrigerant, such as commercial and industrial systems. Small appliances holding 5 pounds or less are not subject to it, and 200 pounds is not the trigger. Beyond the exam: since April 10, 2020 §82.157 has covered class I and class II refrigerants only, and a separate AIM Act rule, 40 CFR §84.106, has applied since January 1, 2026 to appliances holding 15 or more pounds of an HFC or a substitute with a GWP greater than 53. Answer 50 pounds here; on the job, check which of the two rules covers the refrigerant in front of you.
