According to EC F Gas Regulations, how often must refrigeration systems containing between 50 and 500 kg of an HFC refrigerant be leak tested without an automatic leak detector?

Refrigeration systems containing between 50 and 500 kg of HFC refrigerants are required to be leak tested every six months if they do not have an automatic leak detection system. This regulation is designed to ensure that any leaks of refrigerants, which are harmful to the environment due to their high global warming potential, are identified and addressed promptly. Regular testing is essential for preventing excessive emissions and maintaining compliance with environmental standards.

This requirement for a six-monthly interval reflects the balance between operational practicality and environmental protection. Systems of this size could potentially leak a significant quantity of refrigerants if not monitored closely, hence the more frequent testing schedule compared to larger systems or those equipped with leak detection technology.
