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.
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 guide provides the specifier and user with information regarding the use of pre-construction primers (PCPs) on structural steel in shipbuilding. It provides background on the reasons to use and retain PCPs, the types of PCPs and their application and inspection, and the secondary surface preparation processes that are used when PCPs are retained in the final, compatible primary coating system. While this document contains details specific to the shipbuilding industry, the technical concepts related to the application and retention of PCP may apply to other industrial 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.
This standard practice provides technical and quality assurance guidelines for handling and installing nickel alloy, stainless steel, and titanium linings in air pollution control equipment (e.g., FGD systems, ducts, and stacks). The concepts and guidance included in this standard may also be useful in other process industries, but may require modification to meet the requirements of a particular process. This standard is intended to be a basis for preparation of a specification to be agreed on by contracting parties for the installation of wallpaper lining in air pollution control and other process equipment. It is the responsibility of users of this standard to determine the suitability of specific procedures, metals, and alloys for particular applications.
Note: This document was originally published with an error in Section H4.4, Equation (H2), page 33, Section H4.3.3 has a note added, page 33, and Figure H2, Figure H3, Figure H4, and Figure H5, pages 35-38 were enlarged to improve accuracy. These identified errors are corrected. The Errata sheet is included.
This standard practice presents guidelines for establishing requirements to ensure proper application and performance of plant-applied single-layer fusion-bonded epoxy (FBE) coatings to the external surfaces of carbon steel pipe.
Establishes material requirements for resistance to SSC in sour petroleum refining and related processing environments containing H2S either as a gas or dissolved in an aqueous (liquid water) phase with or without the presence of hydrocarbon. This International Standard does not include and is not intended to include design specifications. Other forms of wet H2S cracking, environmental cracking, corrosion, and other modes of failure are outside the scope of this International Standard. It is intended to be used by refiners, equipment manufacturers, engineering contractors, and construction contractors.
Specifically, this International Standard is directed at the prevention of SSC of equipment (including pressure vessels, heat exchangers, piping, valve bodies, and pump and compressor cases) and components used in the refining industry. Prevention of SSC in carbon steel categorized under P-No. 1 in Section IX of the ASME Boiler and Pressure Vessel Code (BPVC) is addressed by requiring compliance with NACE SP0472.
This international standard applies to all components of equipment exposed to sour refinery environments (see Clause 6) where failure by SSC would (1) compromise the integrity of the pressure-containment system, (2) prevent the basic function of the equipment, and/or (3) prevent the equipment from being restored to an operating condition while continuing to contain pressure.
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 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 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.
