SIST EN ISO 10081-2:2005

Overview

SIST EN ISO 10081-2:2005 is a European and international standard that defines the classification of dense shaped basic refractory products containing less than 7% residual carbon after coking. Developed by CEN in alignment with ISO 10081-2:2003, this standard provides clear guidelines for the categorization and designation of these refractory materials. It excludes products with 7% or more residual carbon and covers dense shaped basic refractories both with and without metal plates or reinforcement.

This standard is essential for manufacturers, suppliers, and users of refractory products aiming to ensure consistent quality and suitability for industrial applications where high temperature resistance and chemical stability are required.

Key Topics

• Classification Criteria
  The standard classifies dense shaped refractory products based on chemical composition, specifically focusing on basic refractories with less than 7% residual carbon content.

• Residual Carbon Content
  Products with residual carbon content of 7% or more are excluded from this classification, highlighting the importance of carbon levels in determining product categories.

• Product Types Covered
  Includes dense shaped refractory products with or without antioxidant additives. Metal plates and reinforcements incorporated within these products fall under the scope of this classification.

• Designation System
  Provides a systematic approach to naming and identifying refractory products to facilitate clear communication across manufacturing and supply chains.

Applications

The classification defined in SIST EN ISO 10081-2:2005 applies to a range of industrial settings where dense shaped refractories are critical. Typical applications include:

• Metallurgical Industry
  Used in furnaces, ladles, and converters where materials must withstand extreme temperatures and chemical corrosion.

• Ceramics and Glass Manufacturing
  Durable refractory linings are essential for kilns and glass production equipment.

• Chemical Processing
  Basic refractories play a vital role in reactors and vessels where resistance to alkaline environments is necessary.

• Power Generation
  Used in boilers and incinerators requiring high thermal stability and mechanical strength.

Employing standardized refractory products ensures enhanced performance, safety, and longevity in high-temperature operations.

Related Standards

For comprehensive understanding and implementation, SIST EN ISO 10081-2:2005 aligns and complements key refractory standards such as:

• EN ISO 10081-1 - Classification of dense shaped refractory products containing 7% or more residual carbon (coke carbon).

• EN ISO 10052 - Specifications for high alumina brick products.

• ISO 6611 - Test methods for refractories including carbon content determination.

• EN 12475 series - Additional classifications relevant to shaped and unshaped refractory products.

These related standards, combined with SIST EN ISO 10081-2:2005, offer a structured framework to assess, classify, and select refractory products for various industrial applications.
