What date was recovery equipment required to be certified by a lab to achieve higher evacuation levels?

• A. November 15, 1993
• B. October 1, 1995
• C. December 15, 1994
• D. January 1, 1996

Answer: (A)

Recovery equipment used in refrigerant recovery processes must be certified by a laboratory to demonstrate that it can achieve higher evacuation levels effectively. The date when this certification requirement was implemented is crucial for ensuring that equipment meets the necessary performance standards set by the EPA.

The correct date is November 15, 1993. This requirement was established in response to the need for more effective recovery methods to minimize the release of refrigerants into the atmosphere, which contribute to ozone depletion and climate change. Equipment certified by a recognized laboratory ensures that it can effectively evacuate refrigerants to prescribed levels, thus supporting environmental protection efforts.

Understanding this historical context is important for those involved in HVAC and refrigeration practices, as it reflects the regulatory framework that governs equipment performance and environmental responsibility in the handling of refrigerants.
