This European Standard applies only to condensing units for refrigeration and describes a number of selected performance test methods. These methods provide sufficiently accurate results for the determination of the refrigerating capacity, power absorbed, refrigerant mass flow and the coefficient of performance.
This European Standard applies only to performance tests conducted at the manufacturer's works or wherever the instrumentation and load stability for testing to the accuracy required is...

This International Standard sets requirements for conducting and reporting the results of a compressed
air system assessment (hereafter referenced as an “assessment”) that considers the entire system, from
energy inputs to the work performed as the result of these inputs.
This International Standard considers compressed air systems as three functional subsystems:
— supply which includes the conversion of primary energy resource to compressed air energy;
— transmission which includes movement of...
