Each individual function tested and proven correct in function and resresponse a minimum of two times "(Testing, calibration and commissioning and "Hot Functional Testing") with not less than two month time between individual tests. Copies of test findings results, conditions corrected, response functions logged and submitted for approval

B.	Testing, Calibration and Commissioning: Prior to the actual mechanical/electrical system start up ("Hot-Functional Testing") the Contractor will test, calibrate, and sequence individual mechanical/electrica sub-systems that comprise the entire project. During this period all I/O wiring will be verified (BOTH MONITORING AND CONTROL) through the microprocessor control system (ENABLED/DISABLED), individual field and panel mounted instrumentation calibrated, and all final control elements (fans, pumps, valves, dampers, etc.) exercised through the microprocessor "sub-system software routines". The Contractor shall submit verification "test/calibration data sheets" on the above sub-system startups to both the Instrumentation and Controls Consultant and IBM-Customer for review and sign-off. These sheets shall include a report on any malfunctions and/or operating deficiencies as they occur. IBM-Customer will be notified by the Controls, contractor, prior to sub-system test/calibration, for verfication witnessing. This will serve to aid the IBM-Customer system understanding and operating education, to be reiterated, at a later date, in the consultant/contractor training program. Once sub-system logic and operation i verifie the individual sub-systems will be operated by the Contractor in an integrated overall system fashion ("HOT-FUNCTIONAL TESTING") to verify individual sub-system software interfacing overall system operation, and process guarantees

Readings, other test results at console, and in field recorded independently, with figures not compared until after completion of sub-system test, when results are combined. Console operator to log test data on printer. When set points are reset or mode is changed test data recorded only after conditions have stabilized

G.	DDCS Test Method

1.	Temperature, pressure, humidity indications:

a.	Field measure values with test instruments; local instruments (if any) and remote display at console. Log on printer and record on respective data sheets

2.	Analog limit alarms:

a.	At console, raise low limit to point above actual measured reading in field - alarm should report in, be logged in on printer. For high limit, lowe set point. Record on data sheets field measured condition and logged readings

3.	Set point reset:

a.	In field, measure condition of controlled medium with test instrument. Read corresponding line control air pressure with test gauge. Branch line pressure in same proportion of its full pressure range as measured medium reading is to throttling range of controller. Resetting control point at console should result in proportional change in branch line pressure. Linkage of operators should branch line accordingly. Record observations

4.	Contact indication and alarms:

a.	For sub-systems simulate actual functions or operation in field. Jump contacts where simulation is not practical

b.	High or low limit thermostats: Simulate required limit temperature by immersing sensor in liquid of proper temperature (or other practical means). Alarm should report in at console. Repeat tests with high limit setting reduced and low limit setting increase by 5 F; alarm should not report in at console. Record observations

5.	Mode change:

a.	Change mode setting at console, observe change of controlled element in field

6.	Room Thermostats:

a.	Measure room temperature with test instrument. Measured branch line pressure in same proportion of its full pressure range as temperature reading i to throttling range of thermostat. Change setting of thermostat and observe action of controlled element. Record observations and measurements

7.	Proving Devices:

a.	Operate related systems to activate devices, compare specified resultant function or operation.
