With cutting-edge technology and global recognition, we help you achieve optimal performance and regulatory compliance for your products. Quick turnaround, expert support and non-destructive methods to test if your materials transfer or withstand heat in the most challenging conditions.


What is a Thermal Conductivity Test and Why Do You Need One?

Thermal conductivity refers to 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 during different situations is essential for being confident that your product is fit for purpose in the most extreme conditions, often found in the Aerospace, Oil and Gas and Transportation industries. .

Testing and measurement provide the data to manage what materials are effective, and what operating methods compatible, to use at specific temperatures in diverse applications, whether the material is tasked with insulating, conducting heat, or enduring temperature fluctuations.

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.


Compliance to Internationally Recognized Standards

Element operates laboratories across key locations worldwide, including the UK, USA, Europe, and Asia, providing manufacturers with easy access to reputable testing facilities staffed by knowledgeable experts. We ensure regulatory compliance by conducting rigorous thermal conductivity testing according to internationally recognized standards such as ASTM C518 and ISO 8301. Our commitment to utilizing the latest state-of-the-art testing instrumentation enables us to accurately measure thermal conductivity and assess changes in thermal properties over time, temperature (up to 190 °C, down to -10 °C), and fluid absorption. Our adherence to these standards provides you with assurance that your products will meet industry-specific regulatory requirements.


 Thermal Conductivity Testing Methods and Equipment:

  • Laser Flash Diffusivity (LFD): Compliant with ASTM E1461 standards, ensuring precise thermal diffusivity measurements.
  • Axial Flow: Evaluates thermal conductivity via axial heat flow, offering valuable insights into material performance.
  • Absolute Axial Heat Flow: Provides accurate thermal conductivity measurements across different conditions, suitable for testing materials with low to high conductivity.
  • Comparative Cut Bar: Enables comparative analysis of thermal conductivity among different materials or samples, facilitating informed decision-making.
  • 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.
We analyze your material type, expected conductivity, and desired test temperature range to recommend the most suitable test method that meets your specific project needs, ensuring reliable and actionable insights.

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.

We recommend homogeneous, 12” x 12” samples with 0.5” to 4” thickness. Inhomogeneous materials can produce inconsistent thermal conductivity and are not advised.
