What certification must recovery equipment obtain according to proper recovery techniques?

• A. UL certification
• B. EPA approved laboratory
• C. ISO certification
• D. ANSI certification

Answer: (B)

The correct choice is that recovery equipment must obtain certification from an EPA-approved laboratory. This is essential because the equipment used for refrigerant recovery must meet specific standards set by the Environmental Protection Agency to ensure that it operates safely and effectively. The certification from an EPA-approved laboratory indicates that the recovery equipment has been tested and meets the regulations that prevent the release of refrigerants into the atmosphere, aligning with the goals of the Clean Air Act.

While other forms of certification—like UL (Underwriters Laboratories), ISO (International Organization for Standardization), and ANSI (American National Standards Institute)—are important in the broader context of safety and quality assurance in various industries, the specific requirement for recovery equipment under the EPA regulations is a certification from an EPA-approved laboratory. This focus ensures compliance with environmental laws that regulate refrigerant emissions and protect the ozone layer.
