3.3.3.1.1 Surface profile measurements. One surface profile measurement must be taken for every 200 square feet for the first 1000 square feet; for each additional 500 square feet or less, one profile measurement must be taken.

Profile measurements must be taken in accordance with SFLC Std Spec 6310, paragraph 3.1.8.3 (Surface profile measurements). A “measurement” for surface profile is defined as follows:

• ASTM D4417, Method B: One profile measurement is the average (mean) of 10 individual readings.

• ASTM D4417, Method C: One profile measurement is the average (mean) of 2 individual readings.

3.3.3.1.2 Soluble salt conductivity measurements. 5 conductivity measurements must be taken every 1000 square feet. For submerged (immersed) applications conductivity measurements must not exceed 30 microsiemens/cm.

For non-submerged (non-immersed) applications conductivity measurements must not exceed 70 microsiemens/cm. If a conductivity check fails, clean the surface in accordance with SFLC Std Spec 6310, paragraph 3.1.8.5 (Soluble salt removal).

3.3.3.1.3 Coating thickness measurements. Three area measurements must be taken for the first 1000 square feet;

for each additional 1000 square feet, perform an additional area measurement. A “measurement” for coating thickness is defined as follows:

• SSPC-PA 2 defines an area measurement as 5 separate spot measurements randomly spaced throughout a 100 square foot area.

• SSPC-PA 2 defines a spot measurement as 3 gage readings and each new gage reading the probe must

3.5.2 Test and procedures. The Contractor is required to promptly conduct tests and procedures for the purpose of assessing whether operations are in compliance with applicable Environmental Laws. Analytical work must be done by qualified laboratories; and where required by law, the laboratories must be certified.

3.5.3 Regulatory notifications. The Contractor is responsible for all regulatory notification requirements in accordance with Federal, State and local regulations. In cases where the Coast Guard must also provide public notification, such as storm water permitting, the Contractor must coordinate with the Contracting Officer or COR, and if work is being performed at a USCG Facility, the local Facility Engineer or Engineering Officer. The Contractor must submit copies of all regulatory notifications to the Contracting Officer and the local Facility Engineer or Engineering Officer prior to commencement of work activities. Regulatory notifications must be provided for including but not limited to demolition, renovation, National Pollutant Discharge Elimination System (NPDES) defined site work, and remediation of controlled substances such as asbestos, hazardous waste, and lead paint.

The cable must be adjusted prior to conducting the test so that its length is sufficient to service the aircraft in its normal landing position on the flight deck. If required to make connections to the load bank, it is permissible to conduct the test before installing the helicopter end plug.

2. The voltage at the aircraft end of all installed system servicing cables must be between 24.0 to 29.0 volts for steady state load currents from 0 to 300 amperes.

3. Perform full load test at 300A for 60 minutes. Record values at the conclusion of the full load test.

Increase no-load voltage to 28.5V prior to start of this burn-in test to ensure output voltage will not drop below 24.0 during the burn-in period.

1. The 400Hz Helicopter Service System must be tested by connection to a suitably sized load bank and operated at loads from 2 amps up to the load specified for the Coast Guard H-65 Helicopter (10 KVA).

2. The power supply must be connected to the load bank using the cable supplied to the cutter for aircraft servicing.

If necessary to make the connection to the load bank, the test may be conducted prior to attachment of the helicopter end plug. The cable must be adjusted to the length necessary to service the aircraft in its normal landing position on the flight deck.

3. The required amperage for this test is calculated as:

I = P/[(E)(3)1/2] At P = 10 kVA (for H-65 Helicopter), and E = 200V (line to line), the maximum current required is 28.9 amps.

4. Verify the voltage output is between the limits of 113.0 to 118.0 Volts RMS, line-to-neutral, for steady state loads from no load to full rated load , at 0.7 lagging power factor. To allow for flexibility in loading techniques, the acceptable power factor range is from 0.7 lagging to 0.8 leading power factor.

5. The maximum allowable voltage unbalance is 3.0 volts RMS throughout the load range. Voltage unbalance = maximum difference between RMS phase voltage amplitudes at the utilization equipment terminals (Vmax – Vmin).

6. Verify the phase rotation and frequency is in accordance with Type III power requirements of MIL-STD-1399 Section 300, Part 1.

7. Frequency range must be between 398 to 402 Hz (400 Hz +/- 0.5%).

8. Perform burn-in test at 29A for 60 minutes. Record values at the conclusion of the full load test.
