2.	 If any anchor fails testing, test all anchors of the same type, not previously tested until twenty (20) consecutive anchors pass, then resume the initial test frequency. If the anchors are used for the support and bracing of non-structural components (pipe, duct or conduit), the twenty (20) shall be only those anchors installed by the same trade.
3.	 Test equipment (including torque wrenches) is to be calibrated by an approved testing laboratory in accordance with standard recognized procedures.
4.	 Regardless of which test method is chosen, test values and all appropriate criteria shall be shown on the contract documents.
5.	Anchor diameter refers to the thread size for the wedge and sleeve categories, and to the anchor outside diameter for the sleeve category.
6.	Apply proof test loads to wedge and sleeve anchors without removing the nut if possible. If not, remove nut and install a threaded coupler to the same tightness as the original nut using a torque wrench to apply the test load.
7.	 For sleeve/shell internally threaded categories, verify that the anchor is not prevented from withdrawing by a baseplate or other fixtures. If restraint is found, loosen and shim or remove fixture(s) prior to testing.
8.	 Reaction loads from test fixtures may be applied close to the anchor being tested, provided the anchor is not restrained from withdrawing by the fixture(s).

11.	 If the manufacturer's recommended installation torque is less than the test torque noted in the table, the manufacturer's recommended installation torque should be used in lieu of the tabulated values.
B.	Expansion-type Anchors
1.	 The test load may be applied by any method that will effectively measure the tension in the anchor, such as direct pull with a hydraulic jack, calibrated spring loaded devices, or a calibrated torque wrench. Displacement-controlled anchors such as drop-ins shall not be tested using a torque wrench.
2.	Anchors tested with a hydraulic jack should exhibit no discernable movement during the tension test, e.g., as evidenced by loosening of the washer under the nut.
3.	Anchors tested with a calibrated torque wrench must attain the specified torque within 1/2 turn of the nut.
4.           Exceptions: Undercut anchors that are so designed to allow visual confirmation of full set, need not be tension or torque tested. If the manufacturer's installation

HANGERS AND SUPPORTS FOR ELECTRICAL SYSTEMS 26 05 29 - 6

BUCHANAN HIGH SCHOOL	02/17/2022 COLD BOX REPLACEMENT

torque is less than the specified test torque, use the manufacturer's specified installation torque for testing the anchor.
5.	Apply proof test loads to wedge and sleeve anchors without removing the nut if possible. If not, remove nut and install a threaded coupler to the same tightness as the original nut using a torque wrench to apply the test load.
6.	 For sleeve/shell internally threaded categories, verify that the anchor is not prevented from withdrawing by a baseplate or other fixtures. If restraint is found, loosen and shim or remove fixture(s) prior to testing.
7.	 Reaction loads from test fixtures may be applied close to the anchor being tested, provided the anchor is not restrained from withdrawing by the fixture(s).
8.	Shell type anchors should be tested as follows:
a.	 Visually inspect 25% for full expansion as evidenced by the location of the expansion plug in the anchor body. Plug location of a fully expanded anchor should be as recommended by the manufacturer, or, in the absence of such recommendation, as determined on the job site following the manufacturer's installation instructions. At least 5% of the anchors shall be proof loaded as indicated in the table above, but not less than three anchors per day for each different person or crew installing anchors, or;
b.	Test installed anchors per current edition of the CBC Section 1913A.7. C.	Epoxy-type (adhesive) Anchors
1.	 Epoxy-type (adhesive) anchors shall be tension tested per current edition of the CBC Section 1913A.7. The tension test load shall equal twice the allowable load for the specific location of the anchor to be tested (i.e., accounting for edge distance) or 80% of the yield strength of the bolt (0.8AbFy), whichever is less. The test procedures for expansion-type anchors in the attached table shall also be used for epoxy-type (adhesive) anchors. Torque testing of epoxy-type (adhesive) anchors is not permitted.
2.	 Where epoxy-type (adhesive) anchors are used as shear dowels across cold joints in slabs on grade and the slab is not part of the structural system, testing of those dowels is not required.
3.	Anchors shall exhibit no discernible movement during the tension test. D.	Screw-type Anchors
E.	The following criteria apply for the acceptance of installed anchors:
1.	 Hydraulic ram method: The anchor should have no observable movement at the applicable test load. For wedge and sleeve type anchors, a practical way to determine observable movement is that the washer under the nut becomes loose.
2.	 Torque wrench method: The applicable test torque must be reached within the following limits:
a.	Wedge or Sleeve type: One-half (1/2) turn of the nut.
b.	One-quarter (1/4) turn of the nut for the 3/8 in. sleeve anchor only.

3.6	PAINTING

A.	Touchup:
1.	Clean field welds and abraded areas of shop paint.
2.	 Paint exposed areas immediately after erecting hangers and supports. Use same materials as used for shop painting.
3.	Apply paint by brush or spray to provide minimum dry film thickness of 2.0 mils (0.05 mm).
4.	Comply with the following requirements
a.	Architectural painting specifications
b.	SSPC-PA 1 requirements for touching up field-painted surfaces.
B.	 Galvanized Surfaces: Clean welds, bolted connections, and abraded areas and apply galvanizing-repair paint to comply with ASTM A780.
