Standard Guide to Testing Solvent-Borne Architectural Coatings

SCOPE
1.1 This guide covers the selection and use of procedures for testing solvent-borne coatings to be used on exterior, interior or both types of surfaces (see Note 1). The properties that can be examined or, in some cases, the relevant test procedures are listed in Tables 1 and 2. Note 1-The term "architectural coating" as used here combines the definition in Definitions D16 with that in the FSCT Paint/Coatings Dictionary, as follows: "Organic coatings intended for on-site application to interior or exterior surfaces of residential, commercial, institutional, or industrial buildings, in contrast to industrial coatings. They are protective and decorative finishes applied at ambient temperatures. Often called Trade Sales Coatings." (See 2.3.) Note 2-Architectural coatings that are designed to give better performance than most conventional coatings because they are tougher and more stain- and abrasion-resistant are covered by Guide D3730.
1.2 The types of organic coatings covered by this guide are as follows: (1) Type 1 Interior Low-Gloss Wall Finish, partly covered by Guide D3323, (2) Type 2 Interior Gloss and Semigloss Wall and Trim Enamels, partly covered by Guide D3425, (3) Type 3 Exterior House and Trim Coatings, now covered by Guide D2932, and (4) Type 4 Floor Enamel, Exterior and/or Interior, now covered by Guide D3383.
1.2.1 Each is intended for application by brushing, rolling, spraying, or other means to the materials appropriate for its type, which may include wood, plaster, wallboard, masonry, steel, previously painted surfaces, and other architectural substrates.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
