Determination of the performance of industrial mechanical draught and natural draught towers.

This Part of BS 4485 describes methods for the determination of the performance of industrial mechanical draught and natural draught water cooling towers.

This Part of BS 4485 can also be applied to other forms of cooling towers.

NOTE 1. The matters to be agreed between purchaser and supplier are listed in appendix A.

NOTE 2. The titles of the publications referred to in this standard are listed on page 33.
