Answer:
Recovery equipment was required to be certified by a lab, achieve higher evacuation levels, and have low-loss fittings after November 14, 2014.
Step-by-step explanation:
As of November 14, 2014, regulatory changes in the HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) industry mandated that recovery equipment used in handling refrigerants should meet specific standards. The equipment needed certification by an approved laboratory, higher evacuation levels to ensure efficient removal of refrigerants, and low-loss fittings to minimize emissions during the recovery process. These changes aimed to enhance environmental protection by reducing the release of harmful substances and ensuring the proper handling of refrigerants during maintenance and service activities.
These requirements align with broader efforts to address environmental concerns, specifically related to the management of refrigerants that can contribute to climate change and ozone depletion if mishandled. Compliance with these standards is crucial for professionals in the HVACR industry to mitigate environmental impact and ensure the safe and effective handling of refrigerants.
