52-1.08C(2)(a) Production Test Requirements for Service Splices
<br /> • Production tests shall be performed by the Contractor's independent laboratory for all service splices used in the
<br /> work. A production test shall consist of testing 4 sample splices prepared for each lot of completed splices. The samples
<br /> shall be prepared by the Contractor using the same splice material, position, operators, location, and equipment, and
<br /> following the same procedure as used in the work.
<br /> • At least one week before testing, the Contractor shall notify the Engineer in writing of the date when and the
<br /> location where the testing of the samples will be performed.
<br /> • The 4 samples from each production test shall be securely bundled together and identified with a completed sample
<br /> identification card before shipment to the independent laboratory. The card will be furnished by the Engineer. Bundles of
<br /> samples containing fewer than 4 samples of splices shall not be tested.
<br /> • Before performing any tensile tests on production test sample splices, one of the 4 samples shall be tested for, and
<br /> shall conform to,the requirements for total slip. Should this sample not meet the total slip requirements,one retest,in which
<br /> the 3 remaining samples are tested for total slip,will be allowed. Should any of the 3 remaining samples not conform to the
<br /> total slip requirements,all splices in the lot represented by this production test will be rejected.
<br /> • If 3 or more sample splices from a production test conform to the provisions in this Section 52-1.08C(2),"Service
<br /> Splice Test Criteria,"all splices in the lot represented by this production test will be considered acceptable,provided each of
<br /> the 4 samples develop a minimum tensile strength of not less than 420 MPa.
<br /> • Should only 2 sample splices from a production test conform to the provisions in this Section 52-1.08C(2), "Service
<br /> Splice Test Criteria,"one additional production test shall be performed on the same lot of splices. This additional production
<br /> test shall consist of testing 4 samples splices that have been randomly selected by the Engineer and removed by the
<br /> Contractor from the actual completed lot of splices. Should any of the 4 splices from this additional test fail to conform to
<br /> these provisions,all splices in the lot represented by these production tests will be rejected.
<br /> • If only one sample splice from a production test conforms to the provisions in this Section 52-1.08C(2), "Service
<br /> Splice Test Criteria,"all splices in the lot represented by this production test will be rejected.
<br /> • If a production test for a lot fails, the Contractor shall repair or replace all reinforcing bars from which sample
<br /> splices were removed before the Engineer selects additional splices from this lot for further testing.
<br /> 52-1.08C(2)(b) Quality Assurance Test Requirements for Service Splices
<br /> • For the first production test performed, and for at least one, randomly selected by the Engineer, of every
<br /> 5 subsequent production tests, or portion thereof, the Contractor shall concurrently prepare 4 additional service quality
<br /> assurance sample splices. These service quality assurance sample splices shall be prepared in the same manner as specified
<br /> herein for service production sample splices.
<br /> • These 4 additional quality assurance sample splices shall be shipped to the Transportation Laboratory for quality
<br /> assurance testing. The 4 sample splices shall be securely bundled together and identified by location and contract number
<br /> with weatherproof markings before shipment. Bundles containing fewer than 4 samples of splices will not be tested. Sample
<br /> splices not accompanied by the supporting documentation required in Section 52-1.08B(1), for mechanical splices, or in
<br /> Section 52-1.08B(3),for resistance butt welds,will not be tested.
<br /> • Quality assurance testing will be performed in conformance with the requirements for service production sample
<br /> splices in Section 52-1.08C(2)(a), "Production Test Requirements for Service Splices."
<br /> 52-1.08C(3) Ultimate Butt Splice Test Criteria
<br /> • Ultimate production and quality assurance sample splices shall be tensile tested in conformance with the
<br /> requirements described in ASTM Designation: A 370 and California Test 670.
<br /> • A minimum of one control bar shall be removed from the same bar as,and adjacent to,all ultimate prequalification,
<br /> production, and quality assurance sample splices. Control bars shall be 1)a minimum length of one meter for reinforcing
<br /> bars No.25 or smaller and 1.5 meters for reinforcing bars No.29 or larger, and 2)suitably identified before shipment with
<br /> weatherproof markings that do not interfere with the Engineer's tamper-proof markings or seals. The portion of adjacent bar
<br /> remaining in the work shall also be identified with weatherproof markings that correspond to its adjacent control bar.
<br /> • Each sample splice and its associated control bar shall be identified and marked as a set. Each set shall be identified
<br /> as representing a prequalification,production,or quality assurance sample splice.
<br /> • The portion of hoop reinforcing bar, removed to obtain a sample splice and control bar, shall be replaced using a
<br /> prequalified ultimate mechanical butt splice,or the hoop shall be replaced in kind.
<br /> • Reinforcing bars, other than hoops, from which sample splices are removed, shall be repaired using ultimate
<br /> mechanical butt splices conforming to the provisions in Section 52-1.08C(1), "Splice Prequalification Report," or the bars
<br /> shall be replaced in kind. These bars shall be repaired or replaced such that no splices are located in any "No Splice Zone"
<br /> shown on the plans.
<br /> Ultimate production and quality assurance sample splices shall rupture in the reinforcing bar either: 1)outside of
<br /> the affected zone or 2)within the affected zone, provided that the sample splice has achieved at least 95 percent of the
<br /> Contract No. 10-OM7l 04
