Historically, these are sufficient criteria for refractory testing.

Many of the customers who do refractory testing, especially buyers, need to carry out quality testing and certification of refractories, but do not know what testing standards there are? In addition, refractory testing standards want to be more, the national recommended standard of incomplete statistics reached 52, in addition to a large number of industry standards, local standards.

The so-called a radish a pit, every standard has its meaning of existence, today we will come to understand the standard of refractory testing knowledge bar.

Refractory materials play an important role in Chinas industry. The diversity of testing standards also fully proves the importance that the country attaches to the building of testing system for refractory materials. In fact, in addition to the above testing standards for refractories, there are more subdivided testing standards and testing methods for refractory products. Whether the quality of refractory is qualified and whether the research and development can be carried out smoothly depends on these testing standards to obtain data support.
