ASTM C1190-18(2022)

Standard Practice for Location of Test Specimens from Magnesia-Carbon and Impregnated Burned Basic Brick

SIGNIFICANCE AND USE
4.1 This practice defines a procedure that ensures reasonably consistent preparation of specimens for product testing and evaluation.  
4.2 This practice can be used in the laboratories of producers, users, and general interest parties for research and development or quality control work. It is particularly useful for interlaboratory comparisons on products, for repetitive evaluations or comparisons of products or product quality, and in specifying a uniform preparation practice for specimens for acceptance testing.  
4.3 If pitch-impregnated samples are prepared by wet cutting or drilling, care should be taken in drying them. If the samples are heated to facilitate drying, the temperature to which they are heated should not be so high that it causes drainage of pitch from the samples.  
4.4 Porosities of metal-containing brick must be measured using kerosene or mineral spirits, because using water will result in an artificially low result.
SCOPE
1.1 This practice covers a procedure for preparing test specimens from magnesia-carbon and impregnated burned basic brick. This practice generally concerns preparation of test specimens from brick greater than 13 in. (33 cm) in length. These brick are mainly manufactured for use in electric arc furnaces and basic oxygen furnaces.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM C1190-18(2022): Standard Practice for Location of Test Specimens from Magnesia-Carbon and Impregnated Burned Basic Brick provides a standardized procedure for preparing and selecting test specimens from large refractory bricks. These bricks, primarily magnesia-carbon and pitch-impregnated burned basic types, are extensively used in high-temperature industrial settings such as electric arc furnaces and basic oxygen furnaces.

The standard ensures a consistent approach to specimen preparation, improving the reliability and comparability of test results for critical properties such as modulus of rupture, porosity, and carbon characteristics. This practice is valuable for laboratories involved in product development, quality assurance, and interlaboratory testing programs.

Key Topics

• Specimen Preparation: The practice details how to locate and extract samples from brick exceeding 13 inches (33 cm) in length. It specifies locations to ensure representative and unbiased samples for testing.
• Consistent Testing Procedures: By following the procedures outlined, laboratories can achieve reproducible and comparable results, critical for quality control and product evaluation.
• Handling of Pitch-Impregnated Samples: Special precautions are emphasized for drying pitch-impregnated bricks to prevent the loss of pitch during preparation.
• Porosity Testing: The standard highlights the importance of using kerosene or mineral spirits, rather than water, when measuring the porosities of metal-containing bricks.
• Modulus of Rupture: Procedures for breaking bricks and selecting samples for three-point modulus of rupture tests are described, ensuring physical samples are unaffected by prior breaks.

Applications

ASTM C1190-18(2022) is widely used in the following areas:

• Refractories Manufacturing: Ensures uniformity in testing brick products for use in high-temperature processing equipment, enhancing product reliability and performance.
• Quality Control Laboratories: Supports repeatable testing and verification of physical and mechanical properties, essential for ongoing production quality.
• Interlaboratory Studies: Facilitates direct comparisons of results across multiple labs by standardizing specimen selection and preparation.
• Research and Development: Provides a foundation for R&D teams to evaluate new materials or formulations in a consistent manner.

Industries that benefit from this standard include steelmaking, foundries, and any operations utilizing magnesia-carbon or impregnated burned basic bricks in extreme thermal environments.

Related Standards

For comprehensive product characterization and testing of refractory materials, ASTM C1190-18(2022) references several related ASTM standards:

• ASTM C133: Test Methods for Cold Crushing Strength and Modulus of Rupture of Refractories
• ASTM C607: Practice for Coking Large Shapes of Carbon-Bearing Materials
• ASTM C830: Test Methods for Apparent Porosity, Liquid Absorption, Apparent Specific Gravity, and Bulk Density of Refractory Shapes by Vacuum Pressure
• ASTM C831: Test Methods for Residual Carbon and Carbon Yield in Carbon-Containing Brick and Shapes
• ASTM C1099: Test Method for Modulus of Rupture of Carbon-Containing Refractory Materials at Elevated Temperatures

Utilizing these standards alongside ASTM C1190-18(2022) elevates the accuracy and repeatability of refractory brick testing, supporting high standards in product development, quality assurance, and performance evaluation.
