The purpose of this standard is to provide the means of detecting pinholes, flaws, or holidays in a coating system that may result in its premature failure, thereby possibly decreasing the life expectancy of the asset. This standard documents the equipment and the process of using electrical current to identify these holidays in a repeatable and realistic manner for both field and shop coating applications.

This AMPP standard provides a series of effective and economical test methods to evaluate the performance of candidate offshore platform new construction and maintenance coatings. The testing protocol is established to simulate the offshore environment and based on the major failure modes observed on offshore platforms. The test results will rank the candidate coating systems for end-users to select and coating manufacturers to develop reliable coating systems.
The purpose of this AMPP test method is to standardize the testing methods and conditions used to determine the substrate and surface temperature limits for different thicknesses of insulative coatings used for personnel protection to be in compliance with ASTM C1055. The temperature limits determined when using this test method are specific for each coating tested at a particular thickness and substrate temperature. A standardized test method can validate the temperature limits of a coating used for personnel protection and enable direct comparison of its performance to other commercially available coatings. This test method is intended for use by facility owners, engineers, health and safety specialists, coatings manufacturers, and other interested parties.
This NACE/SSPC joint standard defines the Very Thorough Cleaning (WJ-2) degree of surface cleanliness of coated or uncoated metallic substrates achieved by the use of waterjet cleaning prior to the application of a protective coating or lining. Waterjet cleaning is the use of pressurized surface preparation water for removing coatings and other materials, including hazardous materials, from a substrate to achieve a defined degree of surface cleanliness. Waterjet clean- ing includes various methods such as low-pressure water cleaning (LP WC), high-pressure water cleaning (HP WC), high-pressure waterjetting (HP WJ), and ultrahigh-pressure waterjetting (UHP WJ).
This technical report provides information on the design, installation, and maintenance of protective polymer flooring systems that are applied and directly bonded to concrete. This document does not detail protective polymer flooring systems installed and bonded to other substrates. Installation of polymer coating systems to exterior applications and special service conditions, such as parking decks, balconies, and swimming pool decks, requires additional consideration with respect to the concrete composition and environmental conditions. These application areas are not specifically addressed in this report. This report is intended for use by manufacturers, specifiers, applicators, and facility owners who specify protective polymer flooring systems for concrete.
This Association for Materials Protection and Performance (AMPP) standard test method presents guidelines and procedures for use primarily by corrosion control personnel in the pipeline industry to determine the general condition of a pipeline coating. These techniques are used to measure the coating conductance (inverse of coating resistance) on sections of underground pipelines. This test method applies only to pipe coated with dielectric coatings.
When surveying a coated pipeline system, it may be necessary to determine the conductance of the coating. The conductance of a coating can vary considerably along the pipeline. Variations may be caused by changes in average soil resistivity, terrain, and quality of construction. To obtain data for coating conductance calculations, interrupted structure-to-electrolyte potentials and line current readings are taken at pre-selected intervals. It should be noted that the average soil resistivity has a direct effect on the coating conductance measurement. Because soil resistivity can affect the coating conductance, it must be known when evaluating a section of a pipeline coating.
This AMPP standard practice provides a structure for setting up and maintaining a Corrosion Management System (the System) for existing atmospherically exposed reinforced concrete structures. This standard is concerned with the risk-based management of corrosion to maintain the safe operation of structures and to minimize the risk of unexpected failures and unplanned closures and outages. The Standard applies to any reinforced concrete structure that is atmospherically exposed including: parking structures, bridges, residential or commercial buildings, and any structures at risk of corrosion development.
HISTORICAL DOCUMENT.
In the design of tanks for chemical service, considerations must be given to chemical resistant linings to control corrosion and prevent product contamination. In order to obtain high performance of these linings, special considerations must be taken during the design and fabrication of the tank.
This NACE/SSPC joint standard defines the Clean to Bare Substrate (WJ-1) degree of surface cleanliness of coated or uncoated metallic substrates achieved by the use of waterjet cleaning prior to the application of a protective coating or lining. Waterjet cleaning is the use of pressurized surface preparation water for removing coatings and other materials, including hazardous materials, from a substrate to achieve a defined degree of surface cleanliness. Waterjet clean- ing includes various methods such as low-pressure water cleaning (LP WC), high-pressure water cleaning (HP WC), high-pressure waterjetting (HP WJ), and ultrahigh-pressure waterjetting (UHP WJ).
This standard is based upon the technical requirements for coating repair developed by the National Marine Ship Standardization Technical Committee Ship Repair Branch Technical Committee in China, but may be applicable for use globally provided it meets the field requirements of marine maintenance and fulfills the environmental protection requirements of the appropriate governing body.
This standard practice describes overcoating of the exteriors of railcars. The purpose of this standard practice is to provide methods for testing and application of overcoating materials for the benefit of railcar owners, lessees, and maintenance providers who are charged with developing and executing programs for the maintenance painting of railcars.
This standard practice is intended to provide guidance to those designing, fabricating, and/or maintaining refinery equipment and piping that are exposed to caustic environments.
Caustic is used in many petroleum refinery applications in a wide range of concentrations and temperatures. Caustic stress corrosion cracking (SCC) of carbon steel (CS) equipment has been reported in industry since the 1930s, e.g., in riveted steam boilers. NACE has published guidance for handling sodium hydroxide (NaOH) in the form of a “Caustic Service Chart” since at least the mid-1960s.
