Test: Ambient Temperature (Wet/Dry), Dew Point, Peralatan: Sling Hygrometer, Dew Point Calculator, Surface

The document discusses procedures for environmental testing, surface preparation, coating application, and inspection of coatings on steel structures. It outlines tests for measuring ambient conditions, cleaning and profiling steel surfaces, mixing and applying coatings, and conducting both non-destructive and destructive tests to evaluate coating performance and adhesion. The standards referenced provide specifications for abrasive blasting, surface roughness measurement, coating application methods, dry film thickness measurement, holiday detection, adhesion testing, and other quality control tests.
