הַפשָׁטָה

This guide covers the selection and use of procedures for testing solvent-based architectural coatings for exterior, פְּנִים, 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, consistency (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, בָּרָק, בָּרָק, covering power and yellowness index); Properties of the dry film (התנגדות ללבוש, adhesion, גְמִישׁוּת, resistance to household chemicals, color change of white enamel, washability and cleanability, resistance to foaming, exposure, powdering, בְּדִיקָה, הִסָדְקוּת, erosion, peeling, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, תכולת מים, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification). Use instruments to measure, directional reflection, בָּרָק, בָּרָק, shading power and yellowness index color difference); Properties of the dry film (התנגדות ללבוש, adhesion, גְמִישׁוּת, resistance to household chemicals, color change of white enamel, washability and cleanability, resistance to foaming, exposure, powdering, בְּדִיקָה, הִסָדְקוּת, erosion, peeling, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, תכולת מים, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification). Use instruments to measure, directional reflection, בָּרָק, בָּרָק, shading power and yellowness index color difference); Properties of the dry film (התנגדות ללבוש, adhesion, גְמִישׁוּת, resistance to household chemicals, color change of white enamel, washability and cleanability, resistance to foaming, exposure, powdering, בְּדִיקָה, הִסָדְקוּת, erosion, peeling, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, תכולת מים, 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, בְּדִיקָה, הִסָדְקוּת, erosion, peeling, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, תכולת מים, 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, בְּדִיקָה, הִסָדְקוּת, erosion, peeling, mildew and smoke resistance); And coating analysis (chemical analysis, volatile content, non-volatile volume content, תכולת מים, pigment content, pigment analysis, non-volatile carrier content, carrier separation and non-volatile carrier identification).

סיכום זה הוא סקירה קצרה של תקני הייחוס. זה מיועד לעיון בלבד ואינו חלק רשמי מהתקן; נדרשת התייחסות לטקסט המלא של התקן עצמו לצורך השימוש בו ויישומו. ASTM לא נותן אחריות מכל סוג שהוא, מפורש או משתמע, ואינו מייצג שתוכן תקציר זה מדויק, שלם או חדש.

1.1 This guide covers the selection and use procedures for solvent-based coatings for use on exterior, interior or both types of surfaces (see Note 1). Tables 1 ו 2 list the attributes that can be checked or, במקרים מסוימים, the relevant test procedures.

הערה 1: התנאי “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. ”

הערה 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) סוּג 1 internal low gloss wall finish,

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

(3) סוּג 3 exterior house and trim paint, ו

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

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

1.3 ערכים המבוטאים ביחידות SI ייחשבו כסטנדרט. הערכים המופיעים בסוגריים הם לעיון בלבד.
