Newmont-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.02776-O.DOCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> April 08,2016 <br /> repair or seam section. The color code for indelible markers is to be <br /> determined at the pre-construction meetings, and strictly adhered to. <br /> C. The following nondestructive test procedures are applicable to fusion seaming <br /> and shall be followed by CONTRACTOR. <br /> 1. Seal one end of the seam to be tested. <br /> 2. Insert needle or other approved pressure feed device through the <br /> sealed end of the channel created by the double wedge fusion weld. <br /> 3. Energize the air pump to verify the unobstructed passage of air <br /> through the channel. <br /> 4. Seal the other end of the channel. <br /> S. Energize the air pump to the pressure of approximately 30 psi, close <br /> valve, and sustain pressure for approximately 5 minutes. <br /> 6. If loss of pressure exceeds 3 psi, or pressure does not stabilize, locate <br /> faulty area, repair, and retest. <br /> 7. Remove needle or other approved pressure feed device. <br /> 8. Repair pressure test locations as described in Section 3.11. <br /> 9. Beginning and ending pressures and times, test locations, <br /> documentation number, date, and tester will be indicated with an <br /> indelible marker on the liner at each test interval location. <br /> D. The following procedures shall apply to locations where seams cannot be non- <br /> destructively tested, as determined by CERTIFYING ENGINEER: <br /> 1. If the seam is accessible to testing equipment prior to final installation, <br /> the seam shall be non-destructively tested prior to final installation. If <br /> the seam cannot be tested prior to final installation, the seaming <br /> operations shall be observed by CQA Monitor for uniformity and <br /> completeness. <br /> E. In the event that seam continuity cannot be demonstrated for a non- <br /> destructive test of a fusion seam as outlined above, the CONTRACTOR shall <br /> perform the non-destructive testing over smaller areas as a means of defining <br /> the questionable area. The identified questionable area shall be capped. <br /> 3.9. Destructive Testing <br /> A. CONTRACTOR shall test a minimum of one destructive test sample per five <br /> hundred (500) feet of seam length from a location specified by CERTIFYING <br /> ENGINEER. CONTRACTOR shall not be informed in advance of the sample <br /> location.The samples shall be taken centered over the seam and prioritized as <br /> follows: <br /> Page 17 <br />
