1、 ANSI O5.5-2016 Wood Ground Wire Moulding: Specifications and Dimensions AMERICAN NATIONAL STANDARD FOR WOOD UTILITY PRODUCTS Accredited Standards Committee O5 was first organized in 1924 by the Bell Telephone System and the U.S. Independent Telephone Associations American Standards Association (ASA
2、) Telephone Group. The Exchange Carrier Standards Association (ECSA), which later became the Alliance for Telecommunications Industry Solutions (ATIS), accepted sponsorship and Secretariat responsibility for ASC O5 in 1985. The American Wood Protection Association (AWPA) then assumed the role of Sec
3、retariat, effective January 1, 2011. ASC O5 is jointly accredited with its Secretariat by the American National Standards Institute. This committee develops standards for wood poles, crossarms, braces, and glue laminated timber for utility structures. For more information, visit the ASC O5 website a
4、t www.asco5.org. Founded in 1904, the American Wood Protection Association (AWPA) is a non-profit organization that promulgates voluntary standards for technologies which protect wood from degradation. AWPA Standards are developed by its technical committees in an open, consensus-based process that
5、involves individuals from all facets of wood preservation: Producers of preservatives and preservative components; producers of treated and untreated wood products; end users of treated wood; engineers, architects and building code officials; government entities, academia, and other groups with a ge
6、neral interest in wood preservation. AWPAs Standards are universally specified for wood protection in the USA, and are recognized worldwide. For more information visit the AWPA website at . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirem
7、ents for due process, consensus, and other 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
8、 means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respec
9、t preclude anyone, whether he has 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 in no circumstances give an interpret
10、ation of any American National Standard.

Bevel: 1/32 in (0.8 mm) 1/64 in (0.4 mm). 1)This document is available from the American Wood Protection Association. ANSI O5.5-2016 - 2 - 3.4 Lengths Length of moulding will customarily be 8 ft
40、 (2.44 m). 4 Quality of Lumber Lumber for moulding consists of stock developed in the manufacturing of other standard grades, each piece being of a type suitable for ripping into strips 1 in (25 mm) and wider and 8 feet (2.44 m) and longer. 4.1 Knots Knots shall not exceed 1/4 in (6 mm) in diameter
41、and shall be sound and intergrown. 4.2 Checks Checks shall not exceed 8 in (203 mm) in length or 1/16 in (1.6 mm) in width measured in the dry condition. 4.3 Decay Decay, rot, dote, brash wood, cross breaks (cracks), pitch seams, shakes, through-checks, splits, wane, insect damage, torn grain, and m
42、achine damage are prohibited. 4.4 Bark Bark or reduction of cross-section due to removal of bark shall not be permitted except within 6 in (152 mm) from the ends and shall not exceed 1/8 in (3 mm) in depth. 4.5 Warp Warp shall not exceed 1/2 in (13 mm) in any two ft (610 mm) section at time of deliv
43、ery. 4.6 Cross Grain Cross grain shall not exceed 1 in (25 mm) in any one ft (305 mm) section. 5 Moisture Content All lumber for moulding shall have an average moisture content of 18.0 percent or less to be considered as in the “dry condition”. 6 Manufacturing Requirements 6.1 Workmanship All mouldi
44、ng shall have smooth finished surfaces and square sawn ends. 6.2 Details The groove and shape details of moulding shall conform to the drawing (Figure 1). 7 Preservative Treatment Ground wire moulding shall be treated with pentachlorophenol (PCP-A) or copper naphthenate (CuN) by a pressure process i
45、n accordance with AWPA Standard U1, Commodity Specification A (sawn products) to the requirements of Use Category 4A (UC4A). Initial steaming shall not be permitted. ANSI O5.5-2016 - 3 - 8 Results of Treatment 8.1 Depth of Penetration The preservative shall penetrate 100 percent of the cross-section
46、 (heartwood and sapwood) and shall be determined as follows: 8.1.1 Sampling Method A representative sample of 20 pieces of moulding shall be taken from each charge and cut at least 12 inches (305 mm) from one end. Penetration is determined by visually examining the cross section, using chemical indi
47、cators if necessary. Either production pieces (over-length pieces may be used) or test pieces at least 2 feet (610 mm) in length, or a combination of both may be used. 8.1.2 Surrogate Method If the foregoing Sampling Method is not possible or practical and the volume of an individual charge containi
48、ng moulding consists of more than fifty percent (50%) by volume Douglas-fir crossarms or other large timbers, the moulding shall be considered as meeting the penetration requirement if the largest members in the charge meet the penetration requirements as specified in AWPA Standard T1, Section A. 8.
49、2 Determination of Retention Retention shall be equal to or greater than the retention listed in AWPA Standard U1, Commodity Specification A, UC4A. Note that white oak treated with pentachlorophenol (PCP-A) is treated to refusal per AWPA Standard U1. Retention shall be determined as follows: 8.2.1 Sampling Method An additional 1/4 inch (6 mm) wafer shall be cut from the interior end of each penetration sample from 8.1.1 and combined for retention analysis. 8.2.2 Surrogate Method If penetration is determined by 8.1.2, above, the mouldin
