GB/T 10326-2016 Specifies the size, Appearance and section inspection of shaped refractory products. It specifies the inspection equipment such as measuring tools, and details the process of size measurement, Appearance defect judgment, and section structure observation. Clearly define the size measurement points and tolerance range of each part of the product, enumerate the types and judgment standards of Appearance defects, and introduce the main points of section inspection. Through this standard, the mass of shaped refractory products can be systematically and accurately checked, providing a unified basis for production and acceptance links, ensuring that the products meet the design and use requirements, and ensuring the reliable operation of high temperature industrial equipment.
