Plus, we have the in-house experience and testing chambers to help you obtain certification for your commercial products in North America, the European Union and beyond.

By constantly investing in the newest equipment and continually training to stay abreast of the latest testing techniques, our NTS Longmont labs can handle the most challenging and extreme EMI/EMC tests.

Here are brief descriptions of just a few of the testing services we regularly offer:

  • CBTL Certified Testing – NTS is one of the few CB Testing Laboratories (CBTLs) for electromagnetic compatibility in the United States. We can accommodate CB Scheme EMC testing on medical products for worldwide compliance. Our scope includes 2nd, 3rd, and 4th editions of IEC 60601-1-2.
  • Commercial EMC Testing – NTS has the ability to test a wide range of commercial products, from battery-powered, handheld meters to electrosurgical generators. Full compliance emissions and immunity testing is performed under one roof.
  • Medical EMC Testing – NTS tests electronic devices used in a hospital environment or other medical applications including ventilators, life support equipment, generators, and x-ray equipment as well as smaller devices such as pulse oximeters.
  • Military and Aerospace EMC Testing – EMC testing services on a number of high-profile programs, including the International Space Station and the C-17 Globemaster. MIL-STD testing, trouble-shooting and mitigation and design has been performed on actuators, CCUs, Launch, IR and UV cameras, and more.
  • Prescan & Mitigation – NTS provides engineering-level EMC immunity and emission testing for all tests that will be required for full compliance. Pre-scans are abbreviated tests that aim to identify potential problem areas earlier in the design cycle.
  • Pre-scan Emissions Testing – Enables clients to determine whether or not a compliance problem exists long before it can impact time to market. Pre-scan services have found that we offer an excellent environment for them to trouble-shooting EMC issues.
  • Two fully accredited 10-meter chambers – NTS boasts two fully accredited 10-meter chambers for our emissions testing in Longmont, CO, giving clients the advantage of more reliable data while saving them time and money.

Environmental and Dynamics Testing Services in Colorado

From vibration testing to mechanical impact and shock to temperature, humidity and altitude testing, NTS Longmont performs a complete range of environmental services. Remember that until you verify that your product can withstand the stresses it will meet in its operational environment, you cannot be assured of its value to your customers.

For this reason, environmental simulation and dynamics testing can save your organization both valuable time and money by quickly and accurately identifying weaknesses and/or flaws in your product while they can still be corrected. Why risk a costly recall that can erode customer loyalty and harm your company’s reputation when our environmental services can help you create a best-in-class product?
