Service Advantages

The National Center for Quality Supervision and Testing of Refractory Materials of Building Materials Industry was established in 1989, and the National Center for Quality Inspection and Testing of Refractory Materials (Beijing) was established in 2018, focusing on dense shaped refractory product performance testing for over 30 years.

The center is a domestic, authoritative, professional testing institution for refractory and thermal insulation materials, capable of comprehensive testing for refractories and thermal insulations used in high-temperature industries such as cement, glass, steel, non-ferrous metals, petrochemicals, power generation, and waste incineration.

The center has extensive experience in formulating and revising refractory product and method standards, benchmarking refractory product quality, controlling production quality, analyzing and evaluating service life damage, and resolving quality disputes.

Lead editor of multiple dense shaped refractory product standards, including JC/T 493-2015(2017), JC/T 494-2013(2017), and JC/T 924-2022.

The center covers an area of over 1,100 square meters, equipped with advanced testing instruments, of which approximately 60% are imported, making it one of the most influential national refractory material quality inspection centers in China.
