Abstract
Overview
ISO 12687:1996 - Metallic coatings - Porosity tests - Humid sulfur (flowers of sulfur) test specifies a laboratory method to reveal discontinuities and porosity in metallic coatings that expose a silver, copper or copper-alloy substrate. Commonly called the or test, it detects pores, cracks and other coating breaches by producing brown/black sulfide or oxide corrosion products at exposed substrate sites.
