Introduction
This article shows a brief description of the NACE-SPCC organization, its merger and transformation into AMPP, a summary of the most used and applied Norms and Standards in the achievement of the preservation and maintenance of metallic structures and industrial equipment is presented. Corrosion management policy, strategy and objectives may be contained in separate documents, used to manage threats to assets or asset systems.
Some organizations understand the importance of senior management’s commitment to the mission of conserving business assets. Notable among these organizations is the Association for Materials Protection and Performance (AMPP), the new organization that merges NACE (The National Association of Corrosion Engineers) and SSPC (The Society for Protective Coatings).
AMPP’s corrosion and coatings standards respond to the standardization needs of industries, ensuring a focus on the impact of emerging technologies, new materials and capabilities, and changing regulatory requirements.
Standards Committees (SCs) provide industry professionals, both members and non-members, with a platform to share their subject matter expertise, expand and enhance their professional footprint, and make an indelible impact on technology and industry. AMPP SCs are responsible for the generation, publication and maintenance of all AMPP products that require a consensus-driven process, including standards, technical reports, guides and qualification procedures covering all aspects of surface preparation, application of protective coatings, quality assurance, and corrosion prevention and control worldwide.
NACE standards
NACE International is the leader in the corrosion engineering and scientific community, and is recognized around the world as the foremost authority on corrosion control solutions. It is an organization founded in 1943, it serves about 37,000 members in 140 countries, and its headquarters are in Houston, Texas, USA; with additional offices in the US, Malaysia, China, Brazil and Saudi Arabia.
It was originally known as “The National Association of Corrosion Engineers” when it was established in 1943 by eleven corrosion engineers in the pipeline industry. These founding members participated in a regional cathodic protection group formed in the 1930s, when the study of cathodic protection was introduced. With more than 60 years of experience in developing corrosion prevention and control standards, NACE International has become the world’s largest organization committed to the study of corrosion.
The NACE collection includes standards, recommended practices, test methods and material requirements for corrosion prevention. These publications cover topics such as: external corrosion control in underground metallic piping systems; stainless steel; steel pipes and pipe systems; coatings for underground pipes; removal of oxygen from water; coal tar epoxy; organic corrosion; resistant floor coverings; oil bearing formations; design, installation, operation and maintenance of deep impressed current beds; offshore steel pipes; room temperature sulfide stress cracking; sulfide stress crack resistant metal material for oilfield equipment; and material requirements on precast plastic films for pipe linings.
NACE Standard Practices are methods of selection, design, installation or operation of a material or system when corrosion is a factor. This class of standard may provide details on the construction of a corrosion control system; methods of surface treatment of materials to reduce the requirements for the use of corrosion control devices; criteria for the correct operation and maintenance of a corrosion control system; methods for the proper use of corrosion control techniques; procedures to increase the efficiency, safety and economic benefits of a facility or system; procedures for the proper use of an installed corrosion control system to prevent its deterioration; or other practices that require a description of control techniques or parameters for a system.
NACE test methods are tests related to corrosion prevention and control.
NACE material requirements are standards that define the necessary characteristics of a material when corrosion is a factor in material selection, application and maintenance. This type of standard can include the chemical composition of the material, its mechanical properties, and its physical properties.
NACE standards are written and approved by industry professionals, instructors, professors, government officials, and experts from government and regulatory agencies. Trusted by hundreds of corporations and even the International Maritime Organization (IMO), NACE International standards are the most specified for corrosion control in the world. NACE is a member of the American National Standards Institute (ANSI) as an accredited standards developer.

SSPC standards
SSPC, meanwhile, was founded in 1950 as the Steel Structures Painting Council (SSPC). It is one of the leading sources of information on surface preparation, coatings, environmental regulations, and health and safety issues affecting the industry. The organization is based in Pittsburgh, USA, and has offices in Saudi Arabia, Malaysia and China. Currently, more than 16,000 professionals and 420 companies around the world hold SSPC certifications.
SSPC Coating Material Standards contain requirements for the performance of various types of coatings when tested in accordance with established industry laboratory and field standards. The tests used to establish coating performance vary depending on the type and intended use of the coating, and are selected by industry consensus to be appropriate for performance evaluation of all coatings. Specifiers who plan to use SSPC coating standards in their project specifications must make informed decisions when selecting the appropriate coating system for a specific project.
Protective coatings are designed to work in systems of several compatible coatings: a primer, midcoat, and topcoat, manufacturers often design individual coatings to allow some of these components to be mixed and matched to obtain a system that has the properties of desired performance for a specific service environment. Therefore, one of the first steps in coating selection is to evaluate the coating’s service environment to analyze the stresses it will impose on the various components of a coating system, and thus determine extract properties necessary for optimal coating performance. .
The compatibility of different coatings in a selected system can be determined by standard compatibility tests. Environmental Zones SSPC has developed descriptions of “environmental zones” to characterize the type of environment to which coated steel or concrete will be exposed when in service. For purposes of classifying environmental exposures according to severity, they have been divided into essentially non-corrosive dry interior environmental zones (Zone 0) and severe chemical or temperature exposure (Zones 3 and 4). Zones 3A, 3B and 3C are for exposures to vapors of different concentrations of mineral acids such as hydrochloric acid and nitric acid that give off acid vapors. Zone 3E includes combinations of aggressive chemicals and safe atmospheric exposure. In Zone 3E, oxidizers that may be in the atmosphere include ozone, hydrogen peroxide, and other inorganic peroxides.
New SSPC Standards issued in September 2019
New SSPC-Guide 25, “Use and Selection of Powder Coating Systems for Protective Purposes.” This guide provides general information to assist facility owners and specifiers who are selecting or specifying powder coating systems to protect steel substrates from corrosion. It includes information on generic types of coating powders (pre-applied) and powder coatings (applied coatings), surface preparation and application techniques, and coating system durability and performance.
The new SSPC 26 Guide, “Concrete Floor Covering Selection Guide”, published in September 2019, is a new guide developed to provide specifiers, owners and installers with descriptions of generic floor covering systems for specific service environments, including basic benefits and the limitations of the most widely used polymer chemistries incorporated in these systems. Flooring system selection is dictated by several factors, including existing substrate conditions, performance requirements, installation restrictions, and aesthetics. Criteria are included to help evaluate the various systems. This guide consolidates the selection criteria and information from several existing guides into a single document intended as a reference for concrete flooring system specifiers.
The new SSPC-Guide 27, “Recommended Performance Properties for Liquid-Applied Organic Polymeric Coatings and Liners for Concrete Structures in Municipal Wastewater Facilities,” also issued September 2019, is a revision of SSPC-Paint 44 of the same qualification. This revision converted the previous Paint 44 prescriptive standard into a guidance document, changing the requirements into recommendations. The guide provides recommendations for laboratory performance testing and evaluation criteria for concrete linings intended for defined service environments within municipal wastewater treatment facilities. It can be used by coating specifiers evaluating coating performance properties prior to developing a project specification, as well as coating manufacturers conducting in-house laboratory testing of their products. A new table has also been added that includes recommendations for field performance properties, as assessed by resistance to specific damage mechanisms. Benchmarks for evaluation include adhesion per ASTM D7234, film discontinuity test per ASTM D4787, and coating cure solvent rub test per ASTM D5402.
New SSPC-SP 17 , “Thorough Cleaning of Nonferrous Metals.” SP 17 contains requirements for a defined degree of cleanliness of nonferrous metals prepared by abrasive blast cleaning that must be verified prior to the application of a protective coating or lining system. All visible coatings, oxides, corrosion products and foreign matter must be removed. As with the blast cleaning standards for steel, the standard includes some material and process requirements for dry blast cleaning, including the selection of abrasives and the procedures required before and after the dry blast cleaning process. . Due to the natural appearance variations of different types of metals after cleaning, SP 17 also requires the preparation and acceptance of a Job Reference Standard (JRS) prior to the start of large-scale production work as a way of ensure that the contracting parties agree on the appearance of the substrate after cleaning. Requirements for the preparation of steel substrates with nonferrous metallic coatings, such as galvanized or metallized coatings, are not addressed in this standard.
2019 Revision “SSPC-TU 8 , Safe Use and Handling of Isocyanate-Containing Polyurethane and Polyurea Coatings for Industrial Maintenance Applications.” The intent of the TU is to educate specifiers and workers on how to identify isocyanate content on safety data sheets, how to monitor worker exposure, safe handling practices, and proper use of personal protective equipment when applying coatings. containing isocyanates, public health risk assessment, and waste management.
Conclution
It is evident that there is a trend in the use of international standards, in conclusion, specifiers around the world should start looking for joint SSPC/NACE standards more carefully, their use may be the way to refine the standards used. by industry.
NACE and SSPC have joined forces to serve the corrosion prevention and coatings industry and promote the future of material protection and performance. Now together they make up AMPP The Association for the Protection and Performance of Materials.
