scope:

This standard covers the criteria that must be defined and implemented in a pilot-scale testing program to select water treatment programs for use in specific recirculating cooling water systems.

This standard covers only open recirculating cooling water systems. Closed cooling systems and once-through cooling water systems are specifically excluded.

This standard applies only to systems incorporating shell-and-tube heat exchangers with standard uncoated smooth tubes and cooling water on the tube side. Heat exchangers with shell-side water, plate and frame and or spiral heat exchangers, and other heat-exchange devices are specifically excluded. However, when the test conditions are properly set up to model the surface temperature and shear stress in more complex heat-transfer devices, the test results may predict what may occur in an operating heat exchanger of that design.
