Testing outside controlled ambient conditions adds risk. High temperatures can drive material degradation, expansion, and measurement drift, while low temperatures can cause condensation, frost, and moisture that distort heat transfer and damage equipment.

This edition covers temperature ramping, thermal stabilization, humidity control, and dry gas systems to help maintain accuracy and protect equipment in extreme conditions.

In thermal management, interface materials are often treated as stable. Over time, they can change.

In our latest One Story, One Method, One Takeaway, thermal paste was evaluated in both fresh and aged conditions to understand how performance evolves. While initial results met expectations, aging through drying introduced measurable changes in thermal conductivity.

📈 The data showed an increase in conductivity after aging, along with higher variability, indicating structural or compositional shifts in the material.

The Problem Thermal interface materials (TIMs), such as silicone-based thermal pastes, are designed to enhance heat transfer between electronic components and heat sinks by eliminating air gaps. While their initial performance is well understood, their long-term behavior is often overlooked.

How do EV batteries stay cool under pressure? 🔋❄️

At the recent ASTM International Committee Meeting in Toronto, Dale Hume presented new research on the thermal performance of fluids and solids in EV battery systems, a critical topic as EV adoption continues to grow worldwide.

✅ Using ASTM D7896 and Thermtest’s Transient Hot Wire method, we measured thermal conductivity, diffusivity, and heat capacity of dielectric fluids that help cool lithium-ion batteries directly and efficiently.

✅ We also tested solid materials like Aluminum 6061 using ASTM WK49591 / ISO 22007-2 and our Transient Plane Source method. These materials are essential for battery casings that must be lightweight, durable, and thermally conductive.

🔍 Key takeaway: Testing both fluids and solids provides a complete picture of EV thermal management systems.
