Standard Test Method – Evaluation of Organic-Based Conductive Coating Anodes for Use on Atmospherically Exposed Reinforced Concrete

Published by: 2016-11-05 / 2016-11-05 / 12 pages
This standard provides a test method to evaluate coatings containing conductive carbon pigmentation for use as an anode on atmospherically exposed reinforced concrete. These coatings are commonly applied to steel-reinforced concrete surfaces for the purpose of supplying cathodic protection (CP) current to the embedded steel. The coating systems used for this purpose are intended to serve as an anode material and are not intended to provide a protective barrier coating to the concrete.

This standard is intended for use by consultants, suppliers, and users of CP systems intended to reduce corrosion of embedded steel in atmospherically exposed reinforced concrete. This standard is expected to be used primarily to qualify coatings containing conductive carbon pigmentation as an anode material, rather than as a quality control procedure.

Selection of Pipeline Flow and Internal Corrosion Models

Published by: 2015-01-01 / 2015-01-01 / 16 pages
The purpose of this report is to assist users in making informed technical decisions regarding flow models used to predict the possible locations of internal corrosion, and corrosion models used to predict the severity of internal corrosion at those locations. This report is intended for pipeline operators, model users, consultants, design engineers, and model developers.

Standard for Hull Roughness Measurements on Ship Hulls

Published by: 2016-07-25 / 2016-07-25 / 8 pages
This standard defines the methodology of measuring hull roughness of vessels in dry-dock. This standard does not mention the type of instrument/gauge for such measurements. This standard is limited to a methodology–no interpretation of the results obtained is presented.



One of the factors affecting a ship’s performance and fuel consumption is the roughness of its foul-free underwater hull. The condition and type of paint system used may have a major influence on hull roughness and ship performance. Hull roughness has a major impact on vessel fuel efficiency and exhaust emissions. This standard focuses on the mechanical roughness of the hull. A roughness survey is used to arrive at a measured value to determine the added friction drag caused by the roughened, but foul-free, coated surface.

Slow Strain Rate Test Method for Screening Corrosion-Resistant Alloys for Stress Corrosion Cracking in Sour Oilfield Service

Published by: 2016-01-06 / 2016-01-06 / 24 pages
Provides a standardized method for screening corrosion-resistant alloys (CRAs) for use in oilfield production environments. The SSR test, which is relatively short in duration, incorporates a slow, dynamic strain applied at a constant extension rate. This results in acceleration of the initiation of cracking in susceptible materials, thereby simulating rather severe conditions. The test is useful in evaluating stainless steels and nickel-based alloys for resistance to stress corrosion cracking (SCC) in simulated oilfield production environments at elevated temperatures.

Soluble Salt Testing Frequency and Locations on Previously Coated Surfaces

Published by: 2016-10-04 / 2016-10-04 / 8 pages
This NACE International standard designates where, how often, and the most likely places to test for the presence of surface soluble salts before application of a coating system. This standard establishes industry best practices for soluble salt testing frequencies and locations. It provides a consistent method of soluble salt testing for inclusion in written directions and specifications prepared by asset owners, engineers, consultants, coating contractors, inspectors, and others who are specifying allowable levels of surface soluble salts to prevent premature coating failures. This standard applies only to previously coated substrates and replacement substrate material, and does not include allowable limits of soluble salts.

Metallurgical and Inspection Requirements for Offshore Pipeline Bracelet Anodes

Published by: 2016-03-29 / 2016-03-29 / 16 pages
Sets minimum physical quality and inspection standards for cast sacrificial anodes for offshore pipeline applications. The standard is applicable to typical half-shell or segmented bracelet-type anodes and is not intended to apply to platform, hull, tank, or extruded-type anodes. The section on physical requirements includes information on samples for chemical analysis; anode identification, weight, dimensions, and straightness; insert dimensions and position; insert material; fabrication of inserts by welding; insert surface preparation; surface irregularities on the anode casting; cracks in cast anodic materials; defects; and more.

Application of Cathodic Protection to Control External Corrosion of Carbon Steel On-Grade Storage Tank Bottoms

Published by: 2016-02-03 / 2016-02-03 / 32 pages
The purpose of this standard practice is to present practices for application of CP to control external corrosion of carbon steel on-grade storage tank bottoms that are in contact with an electrolyte. Practices for application of both galvanic anode CP systems and impressed current CP systems are included. Design criteria for the upgrade of existing tanks as well as for newly constructed tanks are included. This standard is maintained by Task Group 013.

Guidelines for Data Collection and Analysis of Railroad Tank Car Interior Coating/Lining Condition

Published by: 2016-08-15 / 2016-08-15 / 12 pages
This NACE International standard is specifically targeted for use by tank car owners, operators, and repairers who are seeking guidance in complying with federal regulations regarding interior coating/lining condition data collection and analysis. This standard provides guidelines for inspecting, rating, and documenting the condition of interior coatings and linings in tank cars. Additionally, procedures for determining disposition of coatings/linings in various stages of distress are outlined, as well as a mechanism for constructive reaction when it becomes apparent that interval lengths require adjustment. There are three nonmandatory Appendixes that provide an example of a coating condition ratings system; an example of a disposition schedule based on the example coating condition rating system; and an example of a coating inspection form as well as a tank car map. It should be noted that issues similar to those discussed here may arise with other bulk liquid transportation containers, and this document may find applicability in those areas as well.
