ANSI C136.46-2013 Page iii 2014 by National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI. ANSI states that the requirements for due process, consensus, and oth

13、er criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means significantly more than a simple

14、majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether they have

15、approved the standards or not, from: manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards, and will under no circumstances give an interpretation of any American Nationa

16、l Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page

17、of this standard. Caution Notice: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards m

30、 Manufacturers Association 1 SCOPE This standard applies to concrete lighting poles used in roadway and area lighting equipment and includes nomenclature, performance criteria, marking and recordkeeping requirements, and certain minimal material needs. It does not cover concrete poles manufactured w

31、ith any modified concrete mix incorporating the use of polymers or other modifiers. 2 NORMATIVE REFERENCES This standard incorporates by reference provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed below. Fo

33、e latest edition of the publication applies (including amendments).

34、National Standard for Roadway and Area Lighting Equipment Vertical Tenons Used with Post-Top Mounted Luminaires CSA A14 Concrete Poles ASTM A82-97a Standard Specification for Steel Wire, Plain, for Concrete Reinforcement 4 DEFINITIONS Anchor Base: A base plate attached to the butt of a pole by appro

35、ved means to accommodate anchor bolts connected to a foundation. Aperture: Any opening in a pole more than 2 in (50 mm) across the width, or more than 4 in (100 mm) along the length of the pole. Arm: A structural member attached approximately perpendicularly to a pole to which a luminaire may be att

36、ached. Bolt Circle: The diameter of a circle that intersects the anchor bolts that are spaced an equal distance from each other. Static Cast Pole: A pole in which the concrete is compacted by means of vibration. Classification Test: The bending test described in sections 11.1 and 11.2 to verify the

37、designed performance of a pole. Cracking Load: The load applied to a pole to create a bending moment that causes the pole to form a crack, while under load attaining a width of 0.004 in (0.1 mm), which usually occurs on the tension face of the pole. ANSI C136.46-2013 Page 2 2014 National Electrical

38、Manufacturers Association Direct Burial, or Direct Embedment: A term used to describe the installation of a pole where a given length of the pole is buried directly in the ground and supported thereafter by compacted fill around it. Effective Projected Area (EPA): The projected area that would have

39、the same drag if its coefficient of drag was 1. Hand hole: A covered opening in the pole, the axis of which is perpendicular to the axis of the pole and located above ground level that provides access to internal wiring and splices. Helical Reinforcement: Wire reinforcement continuously wrapped arou

40、nd the main longitudinal reinforcement to reinforce the pole in a circumferential direction. Ornamental Pole: Any pole with an expanded, stepped, or flared section at ground line that is not subject to a regular taper. Slipfitter: A cylindrical receptacle at the base of a luminaire that fits directl

41、y on to a pole equipped with a tenon. Spun Pole: A pole in which the concrete is distributed and compacted by centrifugal force. standard pole: A pole that is either non-tapered or subject to a standard taper over its entire above ground length. Tenon: A metal sleeve attached to the top of a pole fo

42、r the purpose of supporting a slipfitter. Ultimate Load: The maximum load that the pole can sustain prior to failure. Ultimate Torque: The highest torque in a torsion test the pole can sustain prior to failure. Working Strength: Per AASHTO, a load factor of 1.3 and a reduction in strength factor of

43、0.9 is to be used, resulting in a safety factor of approximately 1.44, unless otherwise specified by the end user. 5 POLE CLASSIFICATION AND DESIGN CONSIDERATIONS 5.1 General 5.1.1 User Provided Specifications Purchaser may specify pole strength by specifying the Class as shown in Table 1. If the pu

44、rchaser does not specify the Class, they must supply the manufacturer with all equipment being assembled on the pole including weights, EPA, location of the parts on the pole and wind zone requirements. The manufacturer shall determine the pole Class required based on the information provided. 5.1.2

45、 Manufacturer Responsibility Poles made in accordance to this standard shall be designed by the manufacturer to meet all requirements specified by the purchaser. This includes, but is not limited to, height above grade, method of installation, color, finish, street lighting equipment mounting detail

46、s, etc. Any custom requirements such as pole coating, Ground Fault Circuit Interrupter (GFCI) receptacles, banner arms, etc. shall be provided by the purchaser.
