True or False: A technician who believes 'most' of the refrigerant has already been removed from a high-pressure appliance may stop the recovery process at that point without verifying the actual required vacuum level was reached.
Not quite. The answer is B: False
Recovery compliance is measured against a specific, verifiable target — the required vacuum level for that appliance and situation — not a technician's subjective sense of 'mostly done.' Stopping early based on a guess, rather than confirming the actual gauge reading against the required level, both violates the regulation and typically leaves enough refrigerant in the system to matter environmentally.

Checked against the official text
Read the eCFR text current through 2026-10-30 of § 82.156. The technician must verify that the applicable level of evacuation has been reached before the appliance or part is opened.
