1. Object of test The object of the test is defined in writing before the test commences and shall be agreed by the parties to the test. 2. Preparation for testing 2.1. General precaution

Every reasonable precaution should be employed in making preparations for conducting any test. Indisputable records shall be made to identify and distinguish the equipment to be tested and the exact method of testing selected. Description, drawing, or photographs may be used to give a permanent, explicit record. Instrument location shall be predetermined, agreed by the parties to the test, and described in detail in test records. 2.2. Agreements

Prior to any tests there shall be agreement on the exact method of testing and the methods of measurement. Among such items: a. Subject of test; b. Selection of instruments; c. Value of measurement uncertainty and method of determining overall test

uncertainty; d. Intent of contract or specification if ambiguities or omissions appear evident; e. Method of operating equipment under test, including that of any auxiliary

equipment, the performance of which may influence the test result; f. Method of maintaining constant operating conditions as near as possible to those

specified in project documents; g. Organization of personnel, including designation of engineer in responsible

charge of test; h. Number of copies of original data required; i. Values of correction for deviations of test conditions from those specified; j. Methods of computing results; k. Conditions for rejection of test run;

l. Location of instruments; m. System alignment or isolation.

3. Pre-test inspection 3.1. All Shop instruments shall be calibrated. A permanent installed tag shall show the

calibration period validity. 3.2. Transducer systems of the same type and manufacture as those purchased for the

installation shall be in use during the factory mechanical running test of monitored equipment. 4. Requirements prior to the mechanical running test 4.1. The contract shaft seals and bearings shall be used in the machine for the

mechanical running test. 4.2. All oil pressures, viscosities, and temperatures shall be within the range of operating

values recommended in the vendor’s operating instructions for the specific unit being tested. For pressure lubrication systems, oil flow rates shall be measured for each bearing housing. 4.3. Test stand oil filtration shall be 10 μm. Oil system components downstream of the

filters shall meet the cleanliness requirements of ISO 10438 (API Standard 614) before any test is started. 4.4. All joints and connections shall be checked for tightness, and any leaks shall be

corrected. 4.5. All warning, protective and control devices used during the test shall be checked

and adjusted as required. 4.6. Testing with the contract coupling or couplings is preferred. 4.7. The vibration characteristics determined by the use of the instrumentation specified

in below paragraphs, shall serve as the basis for acceptance or rejection of the machine. 4.7.1. Shop test facilities shall include the capability of seismic monitoring of casing

vibration. Seismic vibration data, should be recorded in horizontal and vertical directions, at radial planes transverse to each bearing centerline, and also in axial direction, using shop instrumentation during the test.

Note: Compressor equipment configuration may limit measuring device location. 4.7.2. All purchased vibration proximity probes, cables, oscillator-demodulators and

seismic probes shall be in use during the test. If vibration probes are not furnished by the equipment vendor, or if the purchased probes are not compatible with shop readout facilities, then shop devices and readouts may be used. 4.7.3. If vibration proximity probes are specified and supplied, shop test facilities

shall include instrumentation with the capability of continuously monitoring and plotting revolutions per minute, peak-to-peak displacement, and phase angle (x-y-y´). Presentation of vibration displacement and phase marker shall also be by oscilloscope. 4.8. The mechanical running test shall be run at maximum continuous speed for a

minimum of 4 hours. 5. Requirements during the mechanical running test 5.1. During the mechanical running test, the mechanical operation of all equipment

being tested and the operation of the test instrumentation shall be satisfactory. The measured vibration shall not exceed the limits specified in project documents and shall be recorded throughout the operating speed range. 5.2. All real-time vibration data as agreed by the purchaser and vendor shall be

recorded and a copy provided to the purchaser. 5.3. Lube-oil inlet/outlet pressures and temperatures shall be recorded every 30 minutes

during the 4-hour test. 5.4. Discharge air pressures and temperatures (after dryer) shall be recorded every 30

minutes during the 4-hour test. One other measuring point shall be mutually agreed, and the air condition at agreed point shall be measured and recorded too. 5.5. At least one dew point meter shall be installed at the dryer discharge. The air dew

point shall be recorded every 30 minutes during the 4-hour test.

6. Requirements after the mechanical running test is completed 6.1. If replacement or modification of bearings or seals or dismantling of the case to

replace or modify other parts is required to correct mechanical or performance deficiencies, the initial test will not be acceptable, and the final shop tests shall be run after these deficiencies are corrected. 6.2. The casing (including end seals) shall be pressurized with an inert gas to the

maximum sealing pressure or the maximum seal design pressure, as agreed by the purchaser and the vendor; held at this pressure for a minimum of 30 minutes, and subjected to a soap-bubble test or another approved test to check for gas leaks. The test shall be considered satisfactory when no casing or casing joint leak is observed. Note: Test gas mol weight should approximate contract gas mol weight. Helium for low mol weight contract gas and nitrogen or R22 refrigerant gas for high mol weight should be considered. 6.3. The casing (without end seals installed) shall be pressurized to the rated discharge

pressure, held at this pressure for a minimum of 30 minutes, and subjected to a soap-bubble test or another approved method to check for gas leaks. The test shall be considered satisfactory when no casing or casing joint leak is observed.
