1.3 QUALITY ASSURANCE

A. Testing Agency Basic Qualifications: Each Section containing electrical testing may include additional requirements from that specified below.

1. Testing Organization:

a. The testing organization shall be an independent, third party entity which can function as an unbiased testing authority, professionally independent of the manufacturers, suppliers, and installers of equipment or systems being evaluated.

ELECTRICAL TESTING 260560 - 2

b. The testing organization shall be regularly engaged in the testing of electrical equipment devices, installations, and systems.

c. The testing organization shall use technicians who are regularly employed for testing services.

d. An organization having a designation of NETA Accredited Company issued by the InterNational Electrical Testing Association meets the above criteria.

e. The testing organization shall submit appropriate documentation to demonstrate that it satisfactorily complies with these requirements.

2. Testing Personnel:

a. Technicians performing these electrical tests and inspections shall be trained and experienced concerning the apparatus and systems being evaluated. These individuals shall be capable of conducting the tests in a safe manner and with complete knowledge of the hazards involved. They must evaluate the test data and make a judgment on the serviceability of the specific equipment.

b. Technicians shall be certified in accordance with ANSI/NETA ETT-2010, Standard for Certification of Electrical Testing Technicians. Each on-site crew leader shall hold a current certification, Level III or higher, in electrical testing.

PART 3 - EXECUTION

3.1 GENERAL TESTS AND INSPECTIONS

A. If a group of tests are specified to be performed by an independent testing agency, prepare systems, equipment, and components for tests and inspections, and perform preliminary tests to ensure that systems, equipment, and components are ready for independent agency testing.

Include the following minimum preparations as appropriate:

1. Perform insulation-resistance tests.

2. Perform continuity tests.

3. Perform rotation test (for motors to be tested).

4. Provide a stable source of single-phase, 208/120-V electrical power for test instrumentation at each test location.

B. General Wiring Tests

ELECTRICAL TESTING 260560 - 3

1. Prior to final inspection and tests: wiring and connections shall be completed, devices and equipment shall be properly operating, power and lighting circuit and control wiring shall be clearly identified with acceptable tags, and lighting fixtures shall be installed, ready for acceptance.

2. Before devices or equipment is energized, test each wiring system for the following:

a. System is free from short circuits.

b. System is free from ground faults.

c. System is at or below 600 V shall have a minimum installation resistance of 100 megohms when tested with 1000 VDC potential between conductors and between conductors and ground, for a minimum of one minute at 70°F ambient air temperature and dry atmosphere (below 55% RH).

d. Grounding paths have been visually confirmed and acceptable maximum resistance to earth tested.

C. Overcurrent Protective Device Setting

1. Manufacturer's Field Service: Engage a factory-authorized service representative, of electrical distribution equipment to perform or supervise the adjustment of settings on overcurrent protective devices within equipment.

2. Testing: Perform the following device setting and prepare reports:

a. After installing overcurrent protective devices and during energizing process of electrical distribution system, perform the following:

1) Verify that overcurrent protective devices meet parameters used in studies.

2) Adjust devices to values listed in study results.

3. Adjust devices according to recommendations in ANSI/NETA Standards for Acceptance Testing as outlined in Chapter 7, and Tables 10.7 and 10.8 in Standard.

D. Motor Tests

1. After systems are balanced and ready to be turned over to the Owner, test and report motor performance data for motors.

2. Include the following information in the test report:

a. Equipment name and/or number.

b. Manufacturer’s nameplate data, including RPM, horsepower, Volts, full-load amperes per phase, service factor, power factor, manufacturer’s name, motor type and model number.

c. Motor test data, including amperes for each phase, average amperes and phase-to-phase voltage at motor, starter or disconnect switch terminals.

d. Percentage of: (average load test amperes) divided by (nameplate full-load amperes).

e. Size, number and ampere rating of overload heaters. Manufacturer’s motor starter heater table.

f. Breaker and disconnect switch data, including size and manufacturer of switches and fuses and branch circuit wiring.

E. Operational Tests

1. Each piece of electrical equipment, including lighting fixtures, motors and controls shall be operated continuously for minimum test period of one hour.

2. Demonstrate by operating equipment that circuits and devices are in good operating condition. Each item of control equipment shall be operated minimum of five times.

Demonstration shall be performed after wiring tests.

F. Mechanical System Adjustment and Testing

1. Be present during adjustment period and final testing of mechanical systems. Take readings necessary to ensure that electrical systems are operating properly. Tests for mechanical work are detailed under DIVISION 23, MECHANICAL WORK.

2. Take ampere readings at each electrical component, such as motor and heating coil, to determine proper operation.

3. Record readings and submit them in triplicate to Engineer for review.

G. Test and Inspection Reports: In addition to requirements specified elsewhere, report the following:

1. Manufacturer's written testing and inspecting instructions.

2. Calibration and adjustment settings of adjustable and interchangeable devices involved in tests.

3. Tabulation of expected measurement results made before measurements.

4. Tabulation of "as-found" and "as-left" measurement and observation results.

END OF SECTION

3. Adjust devices according to recommendations in ANSI/NETA Standards for Acceptance Testing as outlined in Chapter 7, and Tables 10.7 and 10.8 in Standard.
