HVAC EPA Type I Practice Test

Purity matters in reclaiming refrigerants. Reclaiming is done to restore a specific refrigerant to its approved chemical grade, with strict purity limits. If you recover more than one refrigerant into the same cylinder, the resulting blend has an unknown and uncontrollable composition, which can’t be guaranteed to meet the purity specs for any single refrigerant. Because of that contamination, the material can no longer be reclaimed as that refrigerant, so it’s considered unreclaimable. In practice, such mixed material often ends up handled as waste under regulatory requirements, but the key point is that the reclaimed product itself loses reclaimability due to contamination.
