HAF604 Certification

Delta Controls is pleased to announce that it has received confirmation of its registration with China’s National Nuclear Safety Administration (NNSA) in accordance with The Supervision and Management Regulations for Imported Civilian Nuclear Safety Equipment (HAF604).

HAF604 certification is required for the design and manufacture of all equipment and components that are designed and manufactured outside of China.

The HAF604 registration confirmation covers the design (Cert # 1312) and the manufacture (Cert # 1313) of Delta’s safety related Differential Pressure Switches. 

These switches have a long history of use inside containment in various nuclear power plants around the world in applications ranging from primary steam loop pressure relief systems to rate of change of pressure measurement for Nuclear Steam Supply System (NSSS) leak detection. 

The HAF604 certificates qualify Delta to supply these Switches for use in Class 1E applications in civil nuclear power plants currently in operation, under construction or planned in the People’s Republic of China.  These certificates are available to download from the downloads module opposite.
