(a)Scope. This section is a test procedure that is applicable to a compressor that meets the following criteria:

(1)Is an air compressor;

(2)Is a rotary compressor;

(3)Is not a liquid ring compressor;

(4)Is driven by a brushless electric motor;

(5)Is a lubricated compressor;

(6)Has a full-load operating pressure greater than or equal to 75 pounds per square inch gauge

(psig)and less than or equal to 200 psig;

(7)Is not designed and tested to the requirements of the American Petroleum Institute Standard 619, “Rotary-Type Positive-Displacement Compressors for Petroleum, Petrochemical, and Natural Gas Industries;”

(8)Has full-load actual volume flow rate greater than or equal to 35 cubic feet per minute (cfm), or is distributed in commerce with a compressor motor nominal horsepower greater than or equal to 10 horsepower (hp); and

(9)Has a full-load actual volume flow rate less than or equal to 1,250 cfm, or is distributed in commerce with a compressor motor nominal horsepower less than or equal to 200 hp.

(b)Testing and calculations. Determine the applicable full-load package isentropic efficiency (ηisen,FL), part-load package isentropic efficiency (ηisen,PL), package specific power, maximum full-flow operating pressure, full-load operating pressure, full-load actual volume flow rate, and pressure ratio at full-load operating pressure using the test procedure set forth in appendix A of this subpart.
