Which of the following is a requirement for the processing of reclaimed refrigerant before resale?

The requirement for the processing of reclaimed refrigerant before resale is that it must meet ARI 700 standards. ARI 700 sets the acceptable purity levels for refrigerants that can be marketed and sold. This standard ensures that reclaimed refrigerants are properly recycled, free from contaminants, and suitable for use in refrigeration and air conditioning systems. Meeting these standards is crucial because using contaminated or impure refrigerants can lead to equipment damage, increased emissions, and potential safety hazards.

While maintaining pressure limits, using new containers, and applying color indicators might be relevant in the handling and storage of refrigerants, they are not specific standards that are required for the classification and resale of reclaimed refrigerants as per the established guidelines like ARI 700. Therefore, the emphasis on purity and compliance with these established standards makes it a fundamental requirement for processing reclaimed refrigerant.
