Abstract
Overview
ISO 21575:2026 establishes the standardized powder test method for determining the water resistance of raw optical glass. Published by the International Organization for Standardization (ISO), this standard outlines the general procedures for sample preparation, testing, classification, and reporting of results. Water resistance is a key parameter affecting the durability and performance of optical glass used across scientific, industrial, and technological applications. By providing a systematic assessment method, ISO 21575:2026 supports quality assurance, material selection, and international trade in optical glass.
