scope:

This European Standard specifies test conditions and methods for the determination of the cooling capacity of chilled ceilings and other extended chilled surfaces. The purpose of the standard is to give comparable and repeatable product data. The test method applies to all types of surface cooling systems using any medium as energy transport medium. NOTE: The result is valid only for the specified test set up. For other conditions (i.e. different positions of heat loads, forced flow around the test object, variations in surface area) the producer should give guidance based on full-scale tests. This standard refers to water as the cooling medium throughout, however whereever water is specified any other cooling medium can also be used in the test. Where air is the transport medium this air may not be discharged into the test room. In addition, this standard refers to chilled surfaces and where "surfaces" are specified this should be taken to include ceiling, wall or floor as appropriate.
