SIGNIFICANCE AND USE
3.1 The lining test described in 6.2 may be used to evaluate the chemical resistance characteristics of coating systems for lining surfaces of tanks, vessels and similar facilities used in Coating Service Level I and II applications in a nuclear power plant. For the evaluation of linings in Coating Service Level III water immersion applications in nuclear power plants use the test methods and guidance found in Guide D7230.  
3.2 The specific chemical resistance tests described in 6.1 are dependent upon the relative severity of the service conditions. The specific chemical reagents to be used shall be specified to reflect the intended service conditions.  
3.3 At the discretion of the user, the methods presented may also be used to evaluate coatings and linings for applications in other types of power plants or other industrial services.
SCOPE
1.1 This test method establishes procedures for the evaluation of the chemical resistance of coatings and linings for use in Coating Service Level I and II applications in nuclear power plants.  
1.2 This test method is intended to be used as a screening test to evaluate coatings and linings on steel and concrete substrates.  
1.3 This test method addresses two exposure intervals:
(1) Short Term (Typically 5 days): Such exposures are primarily applicable for coatings exposed to chemical splash or spill.
(2) Long Term (Typically 180 days): Such exposures are primarily applicable for linings exposed to continuous or near-continuous chemical immersion.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D3911-16(2021)(Test Method)
Standard Test Method for Evaluating Coatings Used in Light-Water Nuclear Power Plants at Simulated Design Basis Accident (DBA) Conditions

SIGNIFICANCE AND USE
4.1 This test method is designed to provide a uniform test to determine the suitability of Coating Service Level 1 coatings used inside primary containment of light-water nuclear facilities under simulated DBA conditions. This test method is intended only to demonstrate that under DBA conditions, the coatings will remain intact and not form debris which could unacceptably compromise the operability of engineered safety systems. Deviations in actual surface preparation and in application and curing of the coating materials from qualification test parameters require an engineering evaluation to determine if additional testing is required.  
4.2 Since different plants have different tolerance levels for coating conditions, the definition of appropriate acceptance criteria is to be developed by the license holder based on individual plant engineered safety systems operability considerations.  
4.3 Use of this standard is predicated on the testing facility having a quality assurance program acceptable to the licensee.
SCOPE
1.1 This test method establishes procedures for evaluating protective coating systems test specimens under simulated DBA conditions. Included are a description of conditions and apparatus for temperature-pressure testing, and requirements for preparing, irradiating, testing, examining, evaluating, and documenting the samples.  
1.2 Consideration should be given to testing using worst case conditions (for example, surface preparation, temperature and pressure profile, irradiation, spray chemistry, chemical resistance, etc.) in an effort to reduce the number of tests required by changing plant accident calculations, changes in coating selection, etc.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Evaluating Coatings Applied Over Surfaces Treated With Inhibitors Used to Prevent Flash Rusting of Steel When Water or Water/Abrasive Blasted

SIGNIFICANCE AND USE
3.1 Water-blast cleaning with (SSPC-TR2/NACE 6G 198; SSPC-SP 5 (WAB)/NACE WAB-1; SSPC-SP 10 (WAB)/NACE WAB-2; SSPC-SP 6 (WAB)/NACE WAB-3; SSPC-SP 14 (WAB)/NACE WAB-8); SSPC-SP 7 (WAB)/NACE WAB-4 or without, (SSPC-SP WJ-1/NACE WJ-1; SSPC-SP WJ-2/NACE WJ-2; SSPC-SP WJ-3/NACE WJ-3; SSPC-SP WJ-4/NACE WJ-4) abrasive, results in flash rusting under some environmental conditions. Inhibitors are used to prevent flash rusting while drying and before coating application. The inhibitor or reaction products of the inhibitor on the substrate becomes part of the coating systems. Coating performance may be influenced by the inhibitor. Soluble contaminants or unreacted inhibitors left on the surface under the coating may cause premature failure. This practice includes a comparison of coating performance with and without inhibitors using various laboratory tests to simulate a range of conditions such as high moisture, marine atmospheric or water immersion.  
3.2 The user or specifier must determine the specific test methods to be used and exposure conditions. Some test methods referenced may not be applicable to all types of coatings.
SCOPE
1.1 This practice covers procedures to evaluate the compatibility of coatings with inhibitors used to prevent flash rusting of steel before application of coatings.  
1.2 The inhibitors are used with water-blast cleaning surface preparation and may be used with or without abrasives.  
1.3 The manufacturer of the coatings shall be consulted to ensure compatibility of inhibitors with the coatings.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Qualification Testing of Coatings Used in Coating Service Level I in Nuclear Power Plants

SIGNIFICANCE AND USE
4.1 This guide presents concise guidance and approach to developing a test document for qualifying a coating for CSLI service, whether a new or existing coating. Guidance for evaluating existing qualification test data for applicability is presented in Guide D8104.  
4.2 The requirements for qualification testing can be found in Quality Assurance Criteria III (Design Control), IX (Control of Special Processes), and XI (Test Control) of 10 CFR 50, Appendix B, as implemented, respectively, by Requirements III, IX, and XI of NQA-1. A test document developed per this guide is intended to be compliant with these requirements.  
4.3 This guide implements the guidance provided in Guide D5144 for qualification of coatings for use in CSLI service. Additional guidance is provided in Regulatory Guide 1.54, Revisions 0 through 3, as may be invoked by the licensee.  
4.4 For plants with a license basis that predates the requirements of ANSI N5.12 and N101.2, this guide also is applicable. For these plants, the coatings or coating systems may be designated as acceptable, rather than qualified.  
4.5 All qualification testing shall comply with the licensee’s approved quality assurance program.
SCOPE
1.1 This guide provides an approach to identifying the need for and development of a test document to qualify coatings for Coating Service Level I (CSLI) service in nuclear power plants.  
1.2 It is the intent of this guide to provide a recommended basis for establishing a coatings qualification test document, not to mandate a singular basis for all test documents. Variations or simplifications of the process described in this guide may be appropriate for any given operating or new construction nuclear power plant depending on its licensing commitments.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Asphalt-Base Emulsions for Use as Protective Coatings for Metal

ABSTRACT
This specification establishes the manufacture, testing, and performance requirements of two types of asphalt-based emulsions for use in a relatively thick film as a protective coating for metal surfaces. Type I are quick-setting emulsified asphalt suitable for continuous exposure to water within a few days after application and drying. Type II, on the other hand, are emulsified asphalt suitable for continuous exposure to the weather, only after application and drying. Upon being sampled appropriately, the materials shall conform to composition requirements as to density, residue by evaporation, nonvolatile matter soluble in trichloroethylene, and ash and water content. They shall also adhere to performance requirements as to uniformity, consistency, stability, wet flow, firm set, heat test, flexibility, resistance to water, and loss of adhesion.
SCOPE
1.1 This specification covers emulsified asphalt suitable for application in a relatively thick film as a protective coating for metal surfaces.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Field Collection of Dried Paint Samples for Subsequent Lead Determination

SIGNIFICANCE AND USE
5.1 Although this practice is intended for the collection of dried paint samples in and around buildings and related structures for the subsequent determination of lead content, this practice may also be used to collect paint samples from other structures for lead analysis.3  
5.2 The variability associated with the sampling of dried paint is generally considered to be far higher than the variability associated with the analyses of the paint specimens. Therefore, it is essential that sample collection be properly controlled to produce representative and meaningful samples.  
5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1645 or E1979 and determination of lead using laboratory analysis techniques such as inductively coupled plasma atomic emission spectrometry (ICP-AES) (see Test Method E3203) or flame atomic absorption spectrometry (FAAS) (see Test Method E3193).
SCOPE
1.1 This practice covers the collection of samples of dried paint and other coatings from buildings and related structures.  
1.2 This practice is used to collect samples for subsequent determination of lead on an area basis (milligrams of lead per area sampled) or concentration basis (milligrams of lead per gram of dried paint collected or mass percent of lead in the paint sample collected).  
1.3 This practice does not address the sampling design criteria (that is, a sampling plan that includes the number and location of samples) that are used for risk assessment and other lead hazard activities. See Guide E2115 or Practices E2271/E2271M or E3074/E3074M.  
1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific warning statement is given in 7.4.1.1.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Selection and Use of Liquid Coating Encapsulation Products for Leaded Paint in Buildings

SIGNIFICANCE AND USE
4.1 This standard primarily addresses encapsulant products for residential and child-care facilities. It may also be appropriate for some commercial buildings.  
4.2 Encapsulation provides a means of protecting occupants from exposure to lead in paint in buildings that are likely to remain standing for a long period of time. This nondestructive abatement strategy is useful in situations in which the primary structure needs to remain intact for either historical or economic reasons. Encapsulation offers an abatement strategy that may be more cost effective than abatement by removal of the paint.  
4.3 There are many environmental and use conditions that affect leaded paint liquid coating encapsulation products, and different types of liquid coating encapsulation products have been developed specifically to meet the requirements of the various conditions. Product types include non-reinforced liquid coatings, as well as products for interior or exterior use. These products may be applied over many different surfaces coated with one or more layers of leaded paint and possibly other coatings. Encapsulation products in service are subjected to many kinds of wear. Various colors and finishes are also available. This guide is intended to assist the purchaser in determining which product is most appropriate for the specific conditions under which the product will be used.  
4.4 As described in this guide, an encapsulation product must be compatible with the surface to which it is applied. An encapsulation product must bond to the surface coating, and not cause the subsurface layers to separate or deteriorate.
SCOPE
1.1 This guide is intended to provide building users such as private building owners, contractors, architects, homeowners, and regulatory authorities with assistance in selecting an appropriate liquid coating encapsulation product for architectural residence and child-care facility use situations for abating leaded paint. This guide also provides information that can be used to assist in the following: (1) determining whether a painted surface is suitable for encapsulation, (2) applying a liquid coating encapsulation product, (3) evaluating installed liquid coating encapsulation products, and (4) maintaining the encapsulated surface.  
1.2 This guide applies to any liquid-applied product that relies primarily on adhesion for attachment to the surface and is designed to reduce human exposure to lead in paint.  
1.3 This guide is not intended for use as a training manual. The information contained herein is not all-inclusive and does not provide comprehensive instructions for the selection, application, or maintenance of specific liquid coating encapsulation products. This guide is intended to supplement information supplied by encapsulation product manufacturers and safety requirements established by law. The user of this guide shall refer to the encapsulation product manufacturer’s instructions for encapsulation product application and maintenance.  
1.4 This guide does not cover minimum material performance requirements for liquid coating encapsulation products. Performance specifications for non-reinforced liquid coating encapsulation products are provided in Specification E1795.  
1.5 Encapsulation products for use on industrial steel structures are not covered in this guide. Industrial steel structures include, but are not limited to, bridges, water towers, and tanks.  
1.6 Limited documentation is available on evaluating the field performance of liquid coating encapsulation products. A conservative approach to assessing the selection and use of liquid coating encapsulation products is thus adopted in this guide. As appropriate, the guidance provided within will be revised as additional knowledge regarding how these products perform over time is gained.  
1.7 The user of this guide should follow all regulations promulgated by authorities having jurisdiction regarding the use o...

ASTM D6441-05(2024)(Test Method)
Standard Test Methods for Measuring the Hiding Power of Powder Coatings

SIGNIFICANCE AND USE
5.1 Contrast ratio at a specified film thickness is a useful hiding power parameter for production control and purchasing specifications.  
5.2 The greater the hiding power, the less coating is required per unit area to obtain adequate hiding. Knowledge of hiding power is therefore important in regard to coating costs and for comparing coating value.
SCOPE
1.1 These test methods determine and report the hiding power of a powder coating with respect to two parameters:  
1.1.1 Test Method A—Contrast Ratio at a given film thickness  
1.1.2 Test Method B—Film thickness at 0.98 (98 %) contrast ratio.
Note 1: The measured parameters follow powder coating industry practice by measuring hiding power in relation to film thickness, rather than the “Spreading Rate” function employed in Test Methods D344 and D2805 and other hiding power test methods.
Note 2: Hiding power is photometrically defined as the spreading rate at 0.98 contrast ratio. See definitions of spreading rate and hiding power in Terminology D16, D2805, and the Paint and Coatings Testing Manual.
Note 3: The contrast ratio 0.98 is conventionally accepted in the coatings industry as representing “complete” hiding for reflectometric hiding power measurements. But visually, as well as photometrically, it is slightly less than complete.  
1.2 These test methods cover the determination of the hiding power of powder coatings applied by electrostatic spraying.  
1.3 These test methods determine hiding power by means of reflectometric and thickness gauge measurements. They are limited to coatings having a minimum CIE-Y reflectance of 15 %.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Comparison of the Brush Drag of Latex Paints

SIGNIFICANCE AND USE
5.1 As the brush drag of a paint increases, any natural tendency on the part of the painter to overspread the paint is reduced. When all other factors are held constant, increased brush drag will result in greater film thickness with consequent improvement in durability and hiding. Conversely, sometimes it might be preferred to have a lesser degree of brush drag for easier application (that is, the amount of time and effort in applying a paint to a specific area is reduced with a lesser degree of brush drag).  
5.2 This test method provides a standardized brushout procedure for the evaluation of brush drag as an alternative to customary informal ad hoc procedures. Its objective is to maximize the reliability and precision with which this characteristic may be determined.
Note 1: The brush drag of paints is directly related to their high-shear viscosity. There is generally good rank order agreement between results obtained by this method and Test Method D4287. The sensitivity of this brushout method has been found sufficient to distinguish between brushability corresponding to high-shear viscosity differences not lower than 0.3 poise (0.03 Pa.s). Round robin data show that rank order agreement between the brushout and viscometric methods is poor when both latex and solvent-borne paints are part of the same comparison group. This is the result of these two paint types having markedly different rheological properties that affect the relative perception of brush drag.3
SCOPE
1.1 This test method is a standardized brushout procedure for comparing the brush drag of architectural type solvent-borne paints.  
1.2 With slight modifications this test method is also applicable to solvent-borne paints.
