This guide covers the selection and use of procedures for testing solvent-based architectural coatings for exterior, interieur, or both types of surfaces. The properties that can be checked by the test methods listed herein are as follows: liquid paint properties (skin, conditions in containers, coarse particles and foreign bodies, density or weight per gallon, fineness of dispersion, flash point, odor, absorption, colorant) acceptance, dilution stability, packaging stability, thermal stability and settlement; Coating application and film formation characteristics (brush application performance, brush drag application performance, roll application performance, roll application performance, spray application performance, repair uniformity, samenhang (low shear viscosity), rheology of non-Newtonian liquids, anti-hang, leveling performance, and drying performance); The appearance of the dry film (color appearance, color difference by visual comparison, color difference measured using instruments, directional reflection, glans, glans, covering power and yellowness index); Properties of the dry film (slijtvastheid, adhesion, flexibility, resistance to household chemicals, color change of white enamel, washability and cleanability, resistance to foaming, exposure, powdering, inspection, kraken, erosie, pellen, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, water inhoud, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification). Use instruments to measure, directional reflection, glans, glans, shading power and yellowness index color difference); Properties of the dry film (slijtvastheid, adhesion, flexibility, resistance to household chemicals, color change of white enamel, washability and cleanability, resistance to foaming, exposure, powdering, inspection, kraken, erosie, pellen, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, water inhoud, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification). Use instruments to measure, directional reflection, glans, glans, shading power and yellowness index color difference); Properties of the dry film (slijtvastheid, adhesion, flexibility, resistance to household chemicals, color change of white enamel, washability and cleanability, resistance to foaming, exposure, powdering, inspection, kraken, erosie, pellen, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, water inhoud, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification). Color change of white enamel, washable and cleanability, resistance to foaming, exposure, powdering, inspection, kraken, erosie, pellen, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, water inhoud, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification). Color change of white enamel, washable and cleanability, resistance to foaming, exposure, powdering, inspection, kraken, erosie, pellen, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, water inhoud, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification).

1.1 This guide covers the selection and use procedures for solvent-based coatings for use on exterior, interior or both types of surfaces (zie toelichting 1). Tables 1 En 2 list the attributes that can be checked or, in sommige gevallen, the relevant test procedures.

Opmerking 1: De voorwaarde “architectural coatings” used here combines the definition in the term D16 with the definition in the FSCT Paint/Coatings Dictionary as follows: “Organic coatings intended for field application to residential, commercial, indoor or outdoor surfaces, as compared to industrial coatings, institutional or industrial buildings.” They are protective and decorative finishes applied at ambient temperatures. Commonly referred to as trade sales coatings. ”

Opmerking 2: Architectural coatings are designed to provide better performance than most conventional coatings as they are tougher, more resistant to stains and wear, covered by Guide D3730.

1.2 The following types of organic coatings are covered in this Guide:

(1) Type 1 internal low gloss wall finish,

(2) Type 2 Interior Gloss and Semigloss Wall and Trim Enamels,

(3) Type 3 exterior house and trim paint, En

(4) Type 4 floor enamel, exterior and/or interior.

1.2.1 Each is used for construction by brush, roll, spray or other methods to a material suitable for its type, including wood, plaster, wallboard, masonry, steel, previously painted surfaces and other building substrates.

1.3 Waarden uitgedrukt in SI-eenheden worden als standaard beschouwd. De waarden tussen haakjes zijn alleen ter referentie.

1.4 Deze norm is niet bedoeld om alle veiligheidsproblemen aan te pakken, indien aanwezig, die verband houden met het gebruik ervan. Het is de verantwoordelijkheid van de gebruikers van deze norm om de juiste veiligheid te garanderen, gezondheids- en milieupraktijken en om vóór gebruik de toepasbaarheid van wettelijke beperkingen vast te stellen.

1.5 De internationale standaard is gebaseerd op internationaal erkende standaardisatieprincipes die zijn vastgelegd in de “Besluit over de beginselen voor de ontwikkeling van internationale normen, Richtlijnen en aanbevelingen” uitgegeven door de Commissie technische handelsbelemmeringen (TBT) van de Wereldhandelsorganisatie.
