Standard Specification for Mineral Fiber Thermal Insulating Cement
ABSTRACT
This specification covers mineral fiber thermal insulating materials in the form of dry cement, which, when mixed with a suitable proportion of water, applied as a plastic mass, and dried in place, affords resistance to heat transmission on surfaces operating at a certain range of temperature. Mineral fiber thermal insulating cement shall be composed of mineral fiber and inorganic fillers, with a suitable proportion of heat-resistant binder. The mineral fiber shall consist of rock, slag, or glass processed from a molten state into fibrous form. Asbestos shall not be used as an ingredient or component part of the product. Different test methods shall be performed in order to determine the following properties of the cement: dry covering capacity, volume change upon drying, linear shrinkage, and apparent thermal conductivity.
SCOPE
1.1 This specification covers mineral fiber thermal insulating materials in the form of dry cement, which, when mixed with a suitable proportion of water, applied as a plastic mass, and dried in place, affords resistance to heat transmission on surfaces operating at temperatures between 250 and 1900°F (about 121 and 1038°C).
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 The following safety hazards caveat pertains only to the test methods section of this specification: 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.

Overview
ASTM C195-07(2019): Standard Specification for Mineral Fiber Thermal Insulating Cement establishes criteria for dry cementitious mineral fiber thermal insulation used to inhibit heat transmission on surfaces operating within the temperature range of 250°F to 1900°F (about 121°C to 1038°C). The standard focuses on materials composed of mineral fibers - such as rock, slag, or glass - processed from a molten state, combined with inorganic fillers and heat-resistant binders. Asbestos is explicitly excluded from all formulations. This specification ensures performance through defined testing and manufacturing requirements, supporting consistent quality and safety in industrial and commercial thermal insulation applications.
Key Topics
Material Composition: Specifies that mineral fiber thermal insulating cement must consist of fibrous rock, slag, or glass, along with inorganic fillers and appropriate heat-resistant binders. Asbestos is not permitted.
Thermal Performance: Outlines test methods to evaluate critical performance characteristics, including:
- Dry covering capacity
- Volume change upon drying (shrinkage)
- Linear shrinkage at high temperatures
- Apparent thermal conductivity at various temperatures
Physical and Safety Requirements:
- The cement must display non-combustibility and withstand thermal cycling without significant deformation or degradation.
- Provides guidance on safety, health, and environmental practices during handling and testing.
Sampling and Testing Procedures:
- Offers instructions for representative sampling, preparation, and testing of the insulating cement.
- Includes processes for acceptance, rejection, and retesting of material lots based on compliance with the standard’s requirements.
Applications
ASTM C195 mineral fiber thermal insulating cement is widely used across industries requiring reliable and high-temperature insulation. Typical applications include:
- Industrial Thermal Insulation: Protects piping, tanks, boilers, and equipment operating at elevated temperatures, helping to prevent heat loss and ensure energy efficiency.
- Commercial HVAC Systems: Utilized in ductwork and mechanical systems to maintain temperature stability and reduce energy consumption.
- Steam and Power Generation Facilities: Essential for the insulation of surfaces exposed to high operating temperatures to enhance safety and operational efficiency.
- Petrochemical and Chemical Processing Plants: Applied to process equipment and piping to maintain process temperatures and provide personnel protection.
The material can be mixed with water, applied as a plastic mass, and dried in place, creating a durable thermal barrier tailored to specific shapes and surfaces.
Related Standards
Several ASTM standards support or are referenced within ASTM C195 for testing and terminology consistency, including:
- ASTM C168: Terminology Relating to Thermal Insulation
- ASTM C166 & C356: Test Methods for Covering Capacity, Volume Change, and Linear Shrinkage
