This standard provides a test method to evaluate coatings containing conductive carbon additives for use as an anode on atmospherically exposed reinforced concrete.
Test method to evaluate coatings w/conductive carbon pigmentation as Cathodic Protection (CP) anodes on atmospherically exposed reinforced concrete. Anode coatings are not to provide a protective barrier. HISTORICAL DOCUMENT
Methods to evaluate performance of atmospheric and splash zone maintenance coating systems on platforms. Fixed-leg, semi-submersible, tension-leg, and floating production storage offloading (FPSO).
Evaluation of the performance of offshore atmospheric and splash zone coating systems on platforms. Fixed-leg, semi-submersible, tension-leg, and floating production storage and offloading (FPSOs).
Pruebas para medir potenciales para determinar si un criterio de protección catódica (SP) se logra en un sitio de prueba en tuberías de acero, fiero, cobre o aluminio, subterráneas o sumergidas.
HISTORICAL DOCUMENT. This standard test method provides descriptions of the measurement techniques and cautionary measures most commonly used on underground and submerged piping other than offshore piping to determine whether a specific criterion has been met at a test site. This standard contains instrumentation and general measurement guidelines. It includes methods for voltage drop considerations when structure-to-electrolyte potential measurements are made and provides guidance to minimize incorrect data from being collected and used. This standard is maintained by Task Group 020.
Testing procedures on a buried or submerged steel, cast iron, copper, or aluminum pipeline. Instrumentation and measurement guidelines. Voltage drop considerations for pipe-to-electrolyte measurements.
This technical report presents state-of-the-art information on several commercially available galvanic cathodic protection/prevention systems for protecting atmospherically exposed reinforced concrete structures. The information contained in this report has been provided by key manufacturers of these systems and is intended as a technical resource for engineers responsible for the rehabilitation of reinforced concrete structures. It may also be useful to owners, contractors, and other practitioners related to the field of galvanic cathodic protection (CP). All information related to galvanic CP is intended for atmospherically exposed concrete structures and may not be applicable to concrete containing epoxy-coated reinforcing steel, galvanized, or other coated or nonferrous reinforcement.
This technical report presents evaluation techniques which can potentially be used to complement performance criteria of international standards, especially if the criteria cannot be employed to evaluate the effectiveness of cathodic protection and corrosion control techniques applied to existing reinforced concrete structures, including atmospherically exposed, buried, and submerged structures.
This report:
This report is intended to be useful to architects, structural engineers, architectural conservators, and consulting engineers/contractors who are engaged in refurbishing steel-reinforced concrete structures and buildings.
A natural gas transmission pipeline is routed through South Texas where cathodic protection levels can vary significantly throughout the year. This paper discusses the use of precision electrical resistance type corrosion rate probes and remote monitoring of the probe corrosion rate.
Close interval surveys (CIS) and remote monitoring units (RMUs) can be used as complimentary technologies, essential for validating safe operation of a cathodic protection (CP) system. CIS on a pipeline is typically performed once every few years due to the high cost and time commitment of the process, but the benefit is a high spatial resolution of measurements, with typical spacings between reading locations on the metre length-scale. RMUs installed at test posts with a typical spacing of multiple kilometres between units can be used to measure comparable electrical readings year-round without requiring a human to physically travel to each location.
