This European Standard specifies requirements, test methods and acceptance tests for thermal performances pumping head verification of wet cooling towers and plume abatement for wet/dry cooling towers.
This European Standard is applicable to natural draught wet cooling towers (see in fan assisted natural draught cooling tower (see, wet/dry cooling towers (see and "Mechanical draught cooling towers", except series ones.
It specifies the test methods, the apparatus required, the limitation of errors and the method for results examination.
The acceptance testing covers the verification of the thermal performance data and pumping head of the cooling tower as specified in the contract between the supplier and the purchaser. If these tests are required then this should be recognized at the time of the contract, as additional fittings, and preparations for the test may be required.
Deviations from the rules laid down below as well as additions need special agreement between purchaser and supplier and should be documented.
This standard does not apply to mechanical draught series wet cooling towers which are dealt with in prEN 13741.
NOTE Terms like "design", "values", "guarantee" and "acceptance" used in this standard should be understood in a technical but not in a legal or commercial sense.
