ASTM C1113/C1113M is the ASTM standard for determining the thermal conductivity of refractories by a hot wire method using the platinum resistance thermometer technique. It is used to help measure how refractory materials conduct heat under controlled test conditions, which supports material comparison, specification work, and product evaluation. For manufacturers, laboratories, and buyers, this standard provides a recognized basis for consistent thermal testing and more reliable performance assessment.

Overview of ASTM C1113/C1113M

This standard describes a test method focused on thermal conductivity measurement for refractories, using a hot wire setup with a platinum resistance thermometer technique. ASTM C1113/C1113M is relevant when users need a repeatable way to evaluate heat transfer behavior in refractory products. As an ASTM standard, it helps align testing practices so results can be compared more consistently across materials, suppliers, and quality control programs. The method is especially useful where thermal performance is a key property.

Common use cases of ASTM C1113/C1113M

ASTM C1113/C1113M is commonly used in laboratories, manufacturing quality checks, and product development workflows for refractory materials. It supports thermal conductivity testing during material selection, incoming inspection, and comparative evaluation of refractory formulations or shapes. The standard is also useful for technical teams that need documented test data for specification reviews, procurement decisions, or performance verification. In practice, it helps connect laboratory measurements to real-world thermal insulation and heat-transfer considerations.

Benefits of using ASTM C1113/C1113M

Using ASTM C1113/C1113M helps promote consistent thermal conductivity testing with a recognized ASTM framework. That consistency can improve confidence in reported results, reduce ambiguity in purchasing and specification language, and support quality control across different batches or suppliers. It also helps organizations compare refractory products more fairly and document performance in a way that is easier to audit, communicate, and reference in engineering or compliance activities. For many users, that means lower testing risk and clearer decision-making.
