ISO 14368-3:2003 specifies the nomenclature of defects and the test methods to check them, with minimum physical and aesthetic requirements, for circular mineral and sapphire watch-glasses.
Abstract
Overview
ISO 14368-3:2003 defines qualitative criteria and test methods for circular used in horology. Part 3 of the series specifies the nomenclature for defects (chips, scratches, waves, stains, greying, orange peel, bubbles, etc.), minimum physical and aesthetic requirements, and standardized procedures to verify mechanical and optical properties. The standard supports consistent quality control for watch‑glass production and inspection.
