ISO 9205:1988 PDF

Overview

ISO 9205:1988 specifies a standardized system for the hot-face identification marking of refractory bricks used in rotary kilns. This International Standard, developed by ISO Technical Committee 33 on Refractories, sets out consistent marking practices-namely, notch and color coding systems-to ensure correct installation and easy identification of bricks during kiln lining operations. The standard plays a vital role in supporting kiln safety, efficiency, and maintenance practices within industries heavily reliant on rotary kilns, such as cement manufacturing, metallurgy, and chemical processing.
