At present, there are two organizations that have learned more authority through the media, etc.:

       One is the Luoyang Refractory Research Institute of Sinosteel Group in Luoyang, Henan Province. This is a long-term and then recognized in the industry;

       The other is the China National Building Materials Institute Refractory Center in Beijing, which was approved by the State. In 1991, it passed the Metrological Certification of the State Bureau of Technical Supervision and the qualification of the Ministry of Metallurgy. It is the metallurgical engineering quality inspection agency authorized by the Metallurgical Industry Engineering Quality Supervision Station. In 2003, it passed the China National Laboratory Accreditation Committee for the measurement and certification review and laboratory accreditation preliminary examination, and obtained the national laboratory accreditation certificate. In 2006, it passed the accreditation of the Class A inspection organization of the China National Accreditation Service for Conformity Assessment, and obtained the accreditation certificate of the inspection organization (reproduced in Baidu Encyclopedia). ).

       Therefore these two are more professional. Which is better is that the benevolent sees the wise and sees the wisdom, it is best to consult the people in the refractory industry to evaluate it.

       After all, refractory materials are an indispensable part of our building materials market. They are also visible in our daily life. Due to the performance and parameters of refractory products, they are not simply found in use, so the quality is uneven. Misunderstanding, the phenomenon of indiscriminate charging is also repeated, which will cause chaos and credibility in the entire market. Therefore, the emergence of these professional institutions can at least give refractory users a chance to guarantee their rights and be able to buy them. A refractory product that is reassuring to your own business and has a good reputation for the brand.
