Boric acid products also have a quality indicator system.

Chemical products, which are playing an increasingly important role in our lives, have become more and more significant. When purchasing these products, we must also pay attention to their quality indicator systems. Only when all indicators meet the standards can we purchase the product. In production practice, boric acid manufacturers often use the level of the main content as the sole criterion for determining whether boric acid is qualified. However, they are unaware that the quality indicator system for boric acid products actually consists of seven main indicators. Among these seven indicators, if just one fails to meet the standard requirement, the product is considered unqualified.

In terms of indicator control, the main content index is very easy to control. Even if the impurity indicators are unqualified, the main content index may still meet the standard requirements. Products that have a qualified main content but unqualified impurity indicators are not acceptable to users. Therefore, it is one-sided and unreasonable to evaluate product quality solely based on the level of the main content. From the perspective of a full analysis, the current qualification rate of boric acid produced by the one-step method in China is nearly zero.
