Bedeutung und Zweck 5.1 Graffiti on buildings and structures is a persistent and growing problem. Many applications have been produced that are designed to resist graffiti marks or provide coatings on surfaces from which such marks can be easily removed. The procedure described in this practice provides a set of standard...
Abstract The test method covers procedures for determining pressure spots and adhesion or anti-adhesion properties of organic coatings applied to coil coated or factory coated metal substrates prior to fabrication. Das beschichtete Metall wird in mindestens vier Teile geschnitten, empfohlen, sechs Blätter geeigneter Größe, which are then placed under...
"Standardpraxis für die Coil-Beschichtung unter Verwendung von Wickelzugstangen" (ASTM D 4147) ASTM D4147 ist die Standardmethode zum Auftragen einer dünnen Filmbeschichtung gleichmäßiger Dicke auf eine flache Platte mithilfe eines gewickelten Kratzstabs. ASTM D 4147-1999 Preparation of Coil Coatings with Coiled Wire and Scraper The plate is fixed on...
Bedeutung und Zweck 5.1 This procedure defines a test method for comparing the relative wear resistance of pipe coatings. 5.2 Wear resistance can be used to specify a better coating thickness for candidate materials in the development and research work of studying new coating systems or methods and in quality control. Geltungsbereich 1.1...
Bedeutung und Zweck 4.1 Damage to pipe coatings is almost inevitable during transportation and construction. Breaking or peeling of the pipe coating may expose the pipe to possible corrosion because after the pipe is installed underground, the surrounding soil will be moist and will constitute effective electrolytes. The cathodic protection potential...
