What is Humidity Testing?

Humidity testing evaluates how coatings, materials, and components perform when exposed to high moisture environments. Parts are placed inside controlled environmental chambers where temperature and relative humidity are regulated to simulate real-world exposure conditions.

Laboratory Testing (LTI) performs humidity testing to evaluate corrosion resistance, coating durability, and material stability under continuous moisture exposure. This testing helps identify issues such as blistering, adhesion loss, corrosion, and surface degradation.

Humidity testing is commonly used to evaluate coatings, plated components, and assemblies that may experience prolonged moisture exposure during service life.

Capabilities

Laboratory Testing (LTI) performs humidity exposure testing to evaluate material durability and corrosion resistance under controlled moisture environments.

Continuous humidity exposure testing
Controlled temperature and relative humidity chambers
Evaluation of coating blistering and corrosion resistance
Testing of coated metals, plastics, and assemblies
Accelerated environmental durability evaluation
Specimen preparation and positioning per ASTM requirements

Typical Applications

Humidity testing is used to evaluate the performance of materials and coatings exposed to prolonged moisture and condensation conditions.

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!
