Recovery and recycling equipment manufactured after when must be certified to meet ARI 740 requirements?

The requirement for recovery and recycling equipment to be certified to meet ARI 740 standards originates from the necessity for improved environmental safety and efficiency in refrigerant management. The ARI 740 standard was established to ensure that recovery and recycling equipment effectively handles refrigerants, minimizing leaks and ensuring that refrigerants can be reused safely.

Equipment manufactured after November 15, 1993, must adhere to this certification requirement. This date is significant as it represents the point at which regulatory standards were updated to address concerns about refrigerant emissions and the effectiveness of recovery equipment. The certification process under ARI 740 helps establish performance criteria that equipment must meet to ensure proper recovery and recycling practices are followed, thereby protecting the environment and supporting compliance with the Clean Air Act.

To provide context for why other dates are not applicable, earlier dates would refer to periods before the implementation of these stricter standards, meaning that such equipment might not meet the necessary requirements and thus would not contribute to the intended environmental protections. The later dates indicate periods beyond which the regulatory framework and enforcement were solidified, making November 15, 1993, the critical cut-off for ensuring advanced recovery equipment is certified.
