Which standard specifies the requirements for reclaimed refrigerants used in service?

• A. AHRI Standard 500
• B. AHRI Standard 700
• C. AHRI Standard 900
• D. AHRI Standard 100

Answer: (B)

The question tests knowing which standard governs reclaimed refrigerants used in service. Reclaimed refrigerants are those recovered from equipment, cleaned, and prepared for reuse. AHRI Standard 700 defines what counts as reclaimed refrigerant, requires it come from an approved reclaim facility, and sets quality controls like purity, contamination limits, moisture and acidity levels, and proper labeling and traceability. This ensures the refrigerant reused in systems is safe, compatible with equipment, and not contaminated with other materials. The other AHRI standards address different topics and do not specify the requirements for reclaimed refrigerants used in service.
