Yes, that's an entire school bus in our testing laboratory!

Some engineering challenges require thinking big. Others require bringing the whole bus into the lab!

Here's a look back at one of Clark Testing's structural testing projects, reminding us that engineering comes in all shapes and sizes. Sometimes those shapes happen to be bright yellow and have a lot of windows.

From transportation equipment to heavy industrial machinery, structural and fatigue testing help engineers evaluate strength, durability, and performance under demanding conditions.

At Clark Testing, we've never been afraid to tackle a big testing challenge.

Because when it comes to structural integrity, there's no substitute for putting engineering to the test.

Grease probably isn't something most people think about every day, but imagine how much of our modern world would come to a stop without it.

From aircraft and trains to elevators and industrial machinery, this often-overlooked material plays a pretty important role in keeping everything moving.

Paul Heffernan takes a closer look at the science behind grease and why it deserves a little more credit.

Take a few minutes to give it a read!

Silica exposure remains a serious workplace safety concern across a wide range of industries.

From construction and demolition to stone fabrication, foundries, and manufacturing, workers may be exposed to respirable crystalline silica during activities that generate airborne dust.

OSHA's respirable crystalline silica standards establish:

• **50 µg/m³:** Permissible Exposure Limit (8-hour time-weighted average)
• **25 µg/m³:** Action Level (8-hour time-weighted average)

Understanding workplace exposure levels is an important part of protecting employees and maintaining regulatory compliance.

Clark Testing's Industrial Hygiene laboratory provides crystalline silica analysis using established NIOSH testing methods, helping industrial hygienists, safety professionals, and employers evaluate workplace exposure.

It's not always about whether something works. Sometimes it's about whether it works when it matters most.

Think about the valves and actuators used in nuclear power plants. These components may need to perform reliably after years of service and under demanding operating conditions.

That's where equipment qualification comes in.

At Clark Testing, we help evaluate how critical equipment responds to vibration, seismic events, mechanical aging, and other challenging conditions.

Because when reliability matters, testing makes a difference.

What a great week at APTA TRANSform & EXPO 2026 in Chicago!

Thank you to everyone who stopped by the Clark Testing booth. It was great catching up with familiar faces, meeting new people, and talking about the future of rail and transit.

And a special thank you to Master Gene Garbowsky for bringing the fun with our "Test Your Limits" board-breaking challenge! We loved seeing everyone step up, give it a try, and have a little fun along the way.

Thanks again to everyone who helped make the show a success, including our Clark Testing team who represented us in Chicago!

How do you know critical infrastructure equipment will perform when it matters most?

From extreme temperatures and moisture to vibration and thermal cycling, equipment used in power generation, transportation, telecommunications, and industrial facilities must withstand demanding real-world conditions.

At Clark Testing, environmental testing helps manufacturers evaluate equipment performance, durability, and reliability before it reaches the field.

Nuclear power is entering an exciting new chapter, and Clark Testing has been part of the industry for more than three decades.

Clark's nuclear testing history dates back to 1992, when we acquired Westinghouse Electric's AESD Equipment Qualification laboratory. Since then, our team has continued supporting the commercial nuclear power industry through changing technologies, new requirements, and generations of equipment.

Today, renewed investment in nuclear power, development of Small Modular Reactors (SMRs), and continued modernization of the existing nuclear fleet are creating new opportunities across the industry.

Clark Testing supports manufacturers and suppliers with the testing and technical expertise needed to help demonstrate that critical equipment can perform under the demanding conditions associated with nuclear applications.

From seismic and environmental testing to equipment aging, EMC/EMI, functional testing, and qualification support, we're proud to bring more than 30 years of experience to both today's nuclear fleet and the next generation of nuclear power.
