SIST EN 993-2:1998

Overview

SIST EN 993-2:1998 is a European standard developed by CEN, titled "Methods of test for dense shaped refractory products - Part 2: Determination of true density." This standard specifies a precise method for measuring the true density of dense, shaped refractory products and materials. True density measurement is critical in assessing the quality, performance, and suitability of refractory materials used in high-temperature industrial applications.

The standard is applicable to a wide range of dense shaped refractory products and provides a uniform testing procedure that helps ensure consistency and reliability across the refractory industry.

Key Topics

• Scope and Purpose
  Defines the methodology for accurately determining the true density of dense shaped refractory materials.
• Testing Methodology
  Details the procedure for sample preparation, measurement, and calculation of true density.
• Measurement Accuracy
  Ensures precision in density results which directly affect material performance evaluation.
• Refractory Material Characteristics
  Focuses on dense shaped products which are crucial components in furnaces, kilns, and other high-temperature environments.
• Standard Compliance
  The method aligns with industry best practices, providing standardized data for quality control and performance benchmarking.

Applications

SIST EN 993-2:1998 serves a vital role in industries where refractory materials are employed, such as:

• Steel Production
  Ensuring the reliability of refractory linings in blast furnaces and converters.
• Cement Manufacturing
  Evaluating bricks and shapes used in rotary kilns and preheaters.
• Glass Industry
  Assessing refractories in glass-melting furnaces for durability and thermal efficiency.
• Foundries
  Quality control of refractory molds and linings to withstand casting temperatures.
• Ceramic Industry
  Validating the density of refractory components used in high-temperature ceramic processing.

By determining the true density, manufacturers and users can predict the performance, thermal conductivity, mechanical strength, and lifespan of refractory products more reliably.

Related Standards

To complement SIST EN 993-2:1998, several related standards address other essential properties and testing methods for refractory products, including:

• EN 993-1 - Methods of test for dense shaped refractory products - Part 1: Determination of bulk density and apparent porosity.
• EN 993-3 - Methods of test for dense shaped refractory products - Part 3: Determination of cold crushing strength.
• EN 15309 - Test methods for refractory materials - Chemical analysis.
• ISO 10007 - Quality management - Guidelines for configuration management, important for ensuring traceability of refractory standards and tests.

Using EN 993-2 in conjunction with these standards supports comprehensive quality assurance and product certification within the refractory industry.
