New and Revised SSPC Standards Issued September 2019

Five new or revised SSPC consensus documents are now available on the SSPC Marketplace:

• 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 select or specify powder coating systems to protect steel substrates from corrosion. It includes information about generic types of coating powders (pre application) and powder coatings (applied coatings), surface preparation and application techniques, and coating system durability and performance.
• New SSPC Guide 26, "Concrete Floor Coating Selection Guide," issued in September 2019, is a new guide developed to provide specifiers, owners, and installers with descriptions of generic floor coating systems for specific service environments, including the basic benefits and limitations of the most widely used polymer chemistries incorporated into these systems. Flooring system selection is dictated by several factors, including existing substrate conditions, performance requirements, installation restrictions and aesthetics. Criteria to assist in evaluating the various systems are included. This guide consolidates selection criteria and information from several existing guides into a single document intended as a reference for specifiers of concrete flooring systems.
• New SSPC-Guide 27, “Recommended Performance Properties for Liquid-Applied Organic Polymeric Coatings and Linings for Concrete Structures in Municipal Wastewater Facilities,” also issued in September 2019, is a revision of SSPC-Paint 44 of the same title. This revision converted the former prescriptive standard Paint 44 into a guidance document, changing requirements into recommendations. The guide provides recommendations for laboratory performance testing and evaluation criteria for concrete coatings 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 by coating manufacturers performing in-house laboratory testing of their products. A new table including recommendations for field performance properties, as evaluated by resistance to specific damage mechanisms has also been added. Benchmarks for evaluation include adhesion per ASTM D7234, film discontinuity testing per ASTM D4787, and solvent rub testing for coating cure per ASTM D5402. 
• New SSPC-SP 17, "Thorough Blast Cleaning of Non-Ferrous Metals." SP 17 contains requirements for a defined degree of cleaning of non-ferrous metals prepared using abrasive blast cleaning which 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 process and material requirements for dry blast cleaning, including abrasive selection, and procedures required prior to and after the dry blast cleaning process itself. Due to the natural appearance variations of different types of metals after cleaning, SP 17 also requires preparation and acceptance of a Job Reference Standard (JRS) prior to the startup of full scale production work as a way to ensure the contracting parties are in agreement about the appearance of the substrate following cleaning. Requirements for preparation of steel substrates with non-ferrous metallic coatings such as galvanizing 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 about how to identify isocyanate content from safety data sheets, how to monitor worker exposure, safe handling practices and proper use of personal protective equipment when applying coatings containing isocyanates, evaluation of public health risks, and waste management. This revision contains updated references and a considerable rework of the information in the Worker Exposure discussion section.
