20 SEPTEMBER 2015 COATINGSPROMAG.COM NACE News NACE and IEEE Publish Joint Standards for Power Utility Industry T hree new joint standard practices have been devel- oped by NACE International and the Institute of Electrical and Electronics Engineers (IEEE) to address the need to control corrosion attack and degradation of structures used in the power utility industry and other industries that own or operate metal structures exposed to the risks of corrosion. NACE SP0215-2015/ IEEE Std 1839 T he first joint standard, NACE SP0215-2015/IEEE Std 1839, "NACE/ IEEE Joint Standard Practice for Below- Grade Corrosion Control of Transmission, Distribution, and Substation Structures by Coating Repair Systems," combines the working knowledge and expertise of industr y professionals in asset management who provide guidance on inspection, assessment, and corrosion control for power utility structures. It addresses below-grade corrosion control and provides general coating repair guidelines for in-ser vice carbon steel and galvanized steel electric transmission structures coated w ith poly urethanes, moisture cure urethane (MCU), coal tar, epox y, coal tar epox y, and cold-applied tape systems, including petrolatum and polyethylene. T he standard includes procedures for identif y ing structures that may be at higher risk for below- grade coating degradation; excavating and inspecting the selected structure; assessing the level of corrosion attack and degradation risk to the structure's existing coating system; prioritizing the structures to be repaired; and apply ing repair coatings to the struc- ture when required. Tis standard is a companion to NACE SP0315-2015/IEEE Std 1835 for atmospheric (above grade) corrosion control on steel transmission, distribu- tion, and substation structures, and to NACE SP0415-2015/IEEE Std 1895 for below-grade inspection and assessment of these structures. NACE SP0215-2015/IEEE Std 1839 is available from the NACE Store (www.nace.org/store) as Item #21187-SG. NACE SP0315-2015/ IEEE Std 1835 NACE and IEEE members with the working knowledge and expertise in corrosion assessment and control and utility structure management and maintenance teamed up to write the second joint standard practice, NACE SP0315-2015/IEEE Std 1835, "NACE/IEEE Joint Standard Practice for Atmospheric (Above Grade) Corrosion Control of Existing Electric Transmission, Distribution, and Substation Structures by Coating Systems." Te standard applies to the repair of above-grade atmospheric coatings and defnes the atmospheric area to be coated. It provides guidance for assessing structures for atmospheric corrosion and the level of risk to the structure from corrosion attack and degradation to the existing coating system, and it can serve as a resource for preparing specifcations to achieve the successful coating of utility structures. It includes sections that address safety, inspection and assessment, coating system selection, application methods, contractor qualifcation, and performance monitoring. NACE SP0315-2015/IEEE Std 1835 is available from the NACE Store as Item #21188-SG. NACE SP0415-2015/ IEEE Std 1895 NACE SP0415-2015/IEEE Std 1895, "NACE/IEEE Joint Standard Practice for Below- Grade Inspection and Assessment of Corrosion on Steel Transmission, Distribution, and Substation Structures," is the third of the companion standards written to address the need to control corrosion attack and degradation of structures that are used in the power utility industr y and other industries that ow n and/or operate metal structures exposed to the risks of corrosion. T his is the first NACE standard to include access to an interactive spreadsheet that can be dow nloaded to electronic devices and customized for data collec- tion in the field. Te purpose of this standard is to provide guidance for using common inspection practices and technology on the below-grade areas of steel trans- mission towers, poles, and substation structures to include galvanized, self-weathering, and painted mild steel structures and other similar structures. Te standard includes a section on data collection/prioritization and a gradu- ated, three-tier feld inspection system. Before the publication of this standard, an industry practice to help electric utilities determine a prioritized listing of structures to be inspected or describe an inspection and assessment procedure to evaluate below-grade corrosion problems did not exist. Tis standard, written by industry profes- sionals with working knowledge and expertise in corrosion assessment and control and utility structure manage- ment and maintenance, flls that void. NACE SP0415-2015/IEEE Std 1895 is available from the NACE Store as Item #21189-SG. CP
