ARI 700 defines what aspect of reclaimed refrigerants?

• A. Color
• B. Purity
• C. Odor
• D. Viscosity

Answer: (B)

Purity is the focus. ARI 700 defines what counts as reclaimed refrigerant by setting strict purity requirements. The reason this matters is that contaminants such as moisture, acids, oil carryover, and noncondensables can damage compressors, degrade lubricants, reduce efficiency, and shorten system life. By specifying acceptable impurity levels and the methods to test them, ARI 700 ensures reclaimed refrigerants are clean enough for safe reuse. Color, odor, and viscosity aren’t used by this standard to determine reclaim eligibility, because they’re unreliable indicators of overall cleanliness and performance.
