Domestic Industry Standards Related to Honeycomb Ceramics
A brief overview of relevant domestic industry standards for honeycomb ceramics.
Domestic Industry Standards Related to Honeycomb Ceramics
Honeycomb ceramics are widely utilized in fields such as automotive exhaust purification, industrial denitrification, and regenerative combustion. Domestic standards in this sector are primarily categorized into two types: National Standards (GB/T) and Industry Standards (JC/T, JB/T).
Core Fundamental Standard
GB/T 25994-2010: Honeycomb Ceramics
Scope of Application: Primarily applicable to catalyst carriers for automotive exhaust purification; serves as a reference for other applications.
Key Contents: Visual appearance quality, dimensional tolerances, water absorption, bulk density, coefficient of thermal expansion, isostatic strength, and thermal shock resistance.
Status: The fundamental national standard for honeycomb ceramics.

Summary
The standard system for honeycomb ceramics is anchored by GB/T 25994. It is complemented by specific product standards—covering items such as heat regenerators, combustion plates, and DPF/GPF substrates—as well as general standards for testing methods, thereby encompassing the major fields of application. In practical applications, the appropriate standard should be selected based on the intended use of the product.
