performance code for compressores,vaccum pumps,blowers PTC 9

The purpose of this Code is to establish rules for conducting tests of displacement compres­ sors, vacuum pumps and blowers to determine the fol­ lowing: 

(а) Capacity in relation to speed, inlet pressure, and discharge pressure. 

(б) Power consumption in relation to speed, capacity, inlet pressure, discharge pressure, and intcrcooling. In addition, the Code provides rules for adjusting the test results to reconcile them with specified operating conditions.
