Quick turnaround times, non-destructive methods, and expert support help you verify if your materials properly transfer or withstand heat in the most challenging environments.
What are thermal conductivity testing services at Element?
Thermal conductivity is the speed and amount of heat transferred through a material at a given temperature. Accurately measuring this and understanding how materials will react to different heats and situations is essential to be sure your product is fit for purpose in the most extreme conditions, whether the material is insulating, conducting heat, or enduring temperature fluctuations.
Industries including Aerospace, Oil & Gas and Transportation use thermal conductivity testing to assess changes in thermal properties over time, temperature variations and fluid absorption.
Element’s comprehensive thermal conductivity testing help you determine effective materials and compatible operating methods for specific temperatures.

Methods and solutions offered
Methods and solutions offered
Our comprehensive range of thermal testing methods ensures accurate and reliable results.
- Laser Flash Diffusivity (LFD): Compliant with ASTM E1461 standards for precise thermal diffusivity measurements
- Axial Flow: Evaluates thermal conductivity via axial heat flow
- Absolute Axial Heat Flow: For measuring materials with low to high conductivity across different conditions
- Comparative Cut Bar: Enables comparative analysis of thermal conductivity between different materials or samples
Non-Destructive Test Methods
Testing materials to ensure they can withstand harsh environments and conditions without causing damage is a delicate balance. Methods like Laser Flash Diffusivity and Axial Flow are non-destructive, meaning they provide valuable information about a material's thermal properties without causing significant damage. This allows for rigorous testing without compromising the integrity of the material.

Cutting-edge equipment we use
Cutting-edge equipment we use
- The Probe: Utilizes advanced probing techniques to analyze thermal conductivity properties across various materials and environments.
- Naztech heat flow meter (HFM): Used to characterize material thermal conductivity and “R”-value. The HFM creates a thermal gradient across a sample, measuring the amount of heat flowing in and out of the material. The Fourier equation is then used to calculate the thermal conductivity of the sample.

Frequently asked questions
How do you ensure accuracy and reliability in thermal conductivity testing and measurement?
Customers often face concerns regarding the accuracy and reliability of thermal conductivity testing results, which are crucial for making informed decisions about their materials or products. Element tackles this by employing rigorous testing methodologies and quality control measures to ensure the highest level of accuracy and reliability in our testing processes. Our state-of-the-art equipment and experienced technicians adhere to industry best practices and standards, guaranteeing precise and consistent results. Additionally, we regularly undergo accreditation and proficiency testing to uphold the quality and reliability of our testing services. With Element, you can have assurance in the accuracy of our thermal conductivity measurements, enabling you to make confident decisions.
What is the relationship between R-value and thermal conductivity?
R-value testing considers both thermal conductivity and the material's thickness to assess its insulating properties. While thermal conductivity testing focuses solely on a material's ability to conduct heat.
What type of samples are recommended for Thermal Conductivity testing?
We recommend homogeneous, 12” x 12” samples with 0.5” to 4” thickness. Inhomogeneous materials can produce inconsistent thermal conductivity and are not advised.
