Most engineers understand that a single hot soak or cold exposure can reveal whether a material survives a temperature extreme. Fewer understand why a part can pass both of those tests and still fail in the field. The answer is the transition. Temperature cycling testing measures what happens when a material is forced to move…
A seat fabric qualifies at initial submission. Color holds at specification. Eighteen months later, warranty claims start coming in for fading on door panel trim from the same material family. The fabric passed the test. The trim didn’t get tested the right way. The difference was the method. ISO 105-B06 Procedure 5 is the xenon…
A material can meet every specification at the time of qualification and still fail six months after launch. The part warps after heat aging. The nylon component swells with moisture and no longer fits the assembly. The gasket loses thickness under compression and the seal leaks. Dimensional stability testing measures how a material changes shape…
A coated part can pass UV weathering, look fine in the test lab, and then blister in the field within a season. The UV exposure didn’t cause the blistering. The moisture did. Specifically, the overnight condensation that built up under the coating once the part was installed and the temperature started cycling. Humidity and condensation…
Every material that goes into a vehicle was qualified against a specification. Every specification was written by an engineer. Every test that confirmed compliance was run in a lab like this one. National Engineers Week 2026 runs February 22 through 28 under the theme Transform Your Future. We think about that theme every day. GPTesting…
In many industries (automotive, construction, textiles, solar energy, etc.), materials are engaged in a constant, relentless battle with the environment. Among these adversaries, few are as damaging or pervasive as Ultraviolet (UV) light exposure. UV exposure testing is crucial in reducing a threat that can significantly impact the long-term longevity and safety of critical components….
The automotive industry is in the midst of a profound transformation. It feels like every day there’s a new push for more sustainable vehicles and manufacturing practices. We’re seeing everything from OEMs setting big, ambitious “green goals” to consumers actively seeking out rides with a smaller environmental footprint. This widespread commitment to sustainability is exciting,…
