What is Thermal Exposure Testing?

Thermal exposure testing evaluates how materials, coatings, and assemblies perform when subjected to extreme temperatures and temperature cycling. This type of testing is commonly used to identify cracking, delamination, loss of adhesion, deformation, and other failures caused by thermal stress.

Laboratory Testing (LTI) performs thermal exposure testing using controlled ovens and subzero freezers to support thermal shock, high-temperature exposure, and low-temperature exposure requirements. Thermal exposure can be performed as a standalone test or combined with other environmental exposures to better simulate real-world service conditions.

Capabilities

Laboratory Testing (LTI) performs thermal exposure testing to evaluate durability and performance under controlled high-temperature, low-temperature, and thermal shock conditions.

Thermal shock cycling (rapid temperature transitions)
High-temperature oven exposure
Subzero freezer exposure
Standalone thermal exposure or combined environmental testing programs
Specimen preparation and handling per customer or specification requirements
Evaluation of coated, plated, painted, and assembled components

Typical Applications

Thermal exposure testing is commonly used to evaluate temperature-driven stress and durability across a wide range of products and industries.

Coatings, paints, and protective finishes
Plated components and treated surfaces
Electronics housings and component assemblies
Automotive parts, hardware, and fasteners
Industrial components exposed to fluctuating temperatures

Test Parameters

Temperature setpoints, dwell times, and cycle counts defined by customer or specification requirements
Rapid transitions between low and high temperatures for thermal shock protocols
Programmed exposure cycles to simulate service environments
Testing can be performed before, after, or in sequence with other environmental exposures

Thermal Exposure Methods

Common Thermal Exposure Methods

Thermal shock testing
High-temperature bake exposure
Low-temperature (subzero) exposure
Temperature cycling programs

Thermal exposure testing programs can be configured to meet customer requirements and may be performed as a standalone test or combined with additional environmental exposures when required.

I wanted to thank you guys for really coming through for us. You guys were relentless responding to our requests. LTI Rocks!

It was truly a pleasure to work with you and your team at LTI, and I will always cherish the friendship we have developed over the years. I can honestly say there has not been a single incident where LTI disappointed me.

I just wanted to take a moment here to thank you and LTI team for making it a great year for us. I have been recently getting great feedback on the data that I compiled for our project. And needless to say – the only reason I was able to accomplish this was for your timely testing of all the 100s of coupons I had this year. It all so beautifully played out. Really appreciate your on-time turn-around of data, even though I sometimes make it hard for y’all, haha! And also your very prompt responses to my every question. It has been great working with you all this past year and looking forward to the new year. Thank you once again! Heads-up – we have a ton of samples that will be coming your way in the new year!

I cannot thank you and your team enough for giving our needs your top attention. Thanks to the preliminary reports we received from you this morning, we were able to get the approval we needed in time.

Just wanted to recognize you and the lab for getting these plate specimens done on time under short notice. Thanks so much!

I and my entire high-maintenance crew would like to thank you and your whole crew for getting us the results on our last-minute expedite today … each and every one of you is a rock star in our book!
