4.5 INSULATING FLANGE KITS

A. Responsibility: Insulating flanges shall be inspected and tested by the CONTRACTOR’S CORROSION ENGINEER and in the presence of the ENGINEER, prior to backfilling. Testing of the buried insulating flang e kit prior to backfill will result in non-acceptance of the insulator.

B. Test Method: The assembled flange shall be tested using a Gas Electronics Model 601 Insulation Checker specifically design for testing insulating flanges. The testing shall be done by a qualified CORROSION ENGINEER accepted by the ENGINEER and shall be done in accordance with NACE RPO 286.

C. Acceptance: The installation of the insulating flange kit shall be considered complete when the testing device indicates no shorts or parti al shorts are present.

The CONTRACTOR shall provide assistance in finding any and all shorts or shorted bolts. All disassembly and reassembly necessary for acceptance shall be done at the CONTRACTOR’S expense.

4.6 CATHODIC PROTECTION PERFORMANCE

The c athodic protection system shall be activated and tested by the CONTRACTOR’s CORROSION ENGINEER in the presence of the ENGINEER.

A. Test Method . The installed cathodic protection system testing shall include:
native pipe-to-soil potentials, protected pip e-to-soil potentials, open -circuit anode potentials, and anode current output measurements.

B. Acceptance. Shall be based on achieving the –850 mV criterion as outlined in NACE RPO169-96. All data shall be submitted, in a typed 8 -1/2 X 11 inch report to the City’s ENGINEER and the City’s CORROSION ENGINEER for approval.

C. Compliance With Specifications . Deficiencies or omissions in materials or workmanship found by these tests shall be rectified at the CONTRACTOR’s expense. Deficiencies shall include but are not limited to: broken leads, improper or unclean trenches, lack of 18 -inchor slack wire in test boxes; improperly mounted test boxes; improper installation and testing of insulators; and other deficiencies associated with the workmanship, install ation, and non -functioning equipment.

PART 2 - PRODUCTS (NOT USED)
PART 3 - EXECUTION

3.1 SAFTEY MEASURES

Personnel working on or in direct vicinity of cutting and handling ACP must wear SECTION 02262

ASBESTOS CEMENT PIPE TESTING

3 of 6 SECTION 02262

ASBESTOS CEMENT PIPE TESTING
protective outerwear, eyewear, and respirators per Cal/OSHA Title 8, Section 5144.

B. Provide safeguards to public and personnel safety i ncluding warning signs, fences, lights, and/or other similar items that are necessary for the protection of all personnel during the cutting and handling activities of ACP.

C. Assemble and use temporary enclosures to contain asbestos fibers that may be released and prevent them from release to the atmosphere during cutting. Wet the ACP during cutting to prevent generation of asbestos fibers that may become airborne.

D. The Contractor shall assume full responsibility for personnel and site safety.

3.2 PIPE CUTTING
A. ACP to be removed shall be removed to the nearest pipe joint. Unnecessary cutting or snapping of pipe shall not be allowed, and the shortest ACP segments removed shall be retained for delivery to the laboratory for cutting and testing.

Perform ACP cutting in accordance with Section 02060.

B. No "high speed" cutting tools can be used to cut ACP. Any tools used to cut ACP must not produce amounts of airborne asbestos fibers that exceed the OSHA PEL.

C. "Wet methods " with amended water must be used during any work including cutting or snapping that may produce airborne asbestos fibers that exceed the OSHA PEL.

D. Prior to cutting or snapping , clearly and accurately mark the following on the segment of pipe to be cut and extracted for testing:

1. Crown of the pipe.

2. Owner-approved unique pipe ID (GIS asset ID number) and date.

E. Pipe samples must be 12 inches in length (minimum) and 16 inches (maximum).

F. The Owner’s representative shall be the sole judge of the quality and acceptability of each sample. If a sam ple is deemed unsuitable for testing, provide an additional sample of ACP at no cost to the Owner.

3.3 PIPE HANDLING
A. Avoid contamination of ACP samples (grease or other foreign matter) during extraction.

B. Carefully handle ACP sample to not damage the pipe. Mi shandling of the ACP sample, including damage from transportation and delivery, that results in chipping, scraping, cracking, deforming, or other damage that may void the results of testing will not be acceptable. The Owner’s representative shall be the sole judge of mishandling of the ACP sample. If a sample is mishandled, deliver an additional sample of ACP to the laboratory for testing at no additional cost to the Owner.

C. Carefully bag and seal the sample air -tight with approved packaging materials.

Clearly label the outside of the packaging with the OSHA required label and with the unique pipe ID and date.

D. Individually package and label each sample. Keep packaged samples dry, sealed, and away from direct sunlight and high temperature durin g transportation. All temporary ACP storage containers will be properly labeled and secured. Temporary ACP storage containers will have a bottom, sides and a top that can be locked.

E. Deliver the bagged and sealed sample to the Owner -approved laboratory for EDS testing. Transport ACP material in accordance with Department of Transportation (DOT) and any local requirements.

3.4 LABORATORY TESTING
A. Contract with an Owner-approved laborator y to perform EDS testing on each ACP sample. Laboratory test results shall be delivered to the Owner within six (6) calendar weeks of pipe cutting.

1. Wood PLC 9210 Sky Park Ct. San Diego, CA 92123

2. Applied Materials & Engineering, Inc. 980 41st Street, Oakland, CA 94608

3. Other owner-approved laboratory
B. Arrange for safe delivery of ACP samples to the Owner -approved laboratory.

Coordinate with the laboratory to determine the laboratory’s requirements for the maximum pipe length and all costs associated with handling and cutting of ACP samples. All laboratory personnel who may come into contact with ACP will wear personal protective equipment and use processes so that they will not be exposed to airborne asbestos fibers at a level that will be a hazard to their health.

C. Equipment:

1. EDS equipment shall be equipped with a scanning electron microscope (SEM) capable of producing high resolution SEM images of the cross- section (where analyses are being performed) and shall be able to generate EDS elemental area maps or phase maps.

D. Laboratory Testing and Reporting:

1. Phenolphthalein Stain Testing:
a. Prior to conducting testing, coordinate with the Owner to verify testing requirements, measurement and establish a testing protocol. Confirm that ACP samples are labeled for pipe crown, pipe ID (GIS asset ID number) and date.
b. Neatly cut the ACP sample in t he laboratory and apply phenolphthalein to one surface of the pipe cross section. c. Identify the location on the pipe cross section that exhibits the least amount of phenolphthalein staining. Record this location relative to the pipe crown (i.e., 12 o’clock) as the location where 10 equally spaced EDS measurements will be made on each pipe sample.
d. Measure and record the pipe wall thickness and the dimensions of the most phenolphthalein stain loss at the outer and inner pipe surfaces.

2. EDS Testing:
a. Calibrate EDS equipment by using test peaks of known energy, covering the full analytical span prior to testing.
b. Label 10 equally spaced measurement locations on the pipe cross section in a line perpendicular to the inner and outer wall tangent s (i.e. along the line used to measure wall thickness) , with P oint 1 being closest to the outer pipe surface and Point 10 being closest to the inner pipe surface.
c. Measure and record the percent by weight of each of the following elements at the 10 equally spaced locations: Carbon (C), Oxygen (O), Magnesium (Mg), Aluminum (AI), Silicon (Si), Calcium (Ca), and Iron (Fe).
d. Allow sufficient process time for analysis and ensure a statistically significant number of counts in order to decide if a peak is present or absent. Present a table of maximum number of counts and atomic percentage.
e. Provide the measurements and test data to the Owner in a summary report and in Microsoft Excel file format (.xlsx). See Figure 1 for a sample of the laboratory test data reporting format.

3. Re-bag ACP sample in 6-mil clear plastic . Seal and store ACP sample s until confirmation from the Owner that the summary report and test data are received and complete.

4. Transmit the summary report and Excel data file via email to the City’s Project Manag er. Title the transmittal, report and data file with the City Project Number, Project Name, and Pipe ID Number.

5. After confirmation, the lab oratory shall legally dispose of each ACP sample at no additional cost to the Owner.
