My company has used DNB many times in the past whenever we need a MIL-STD-810 or MIL-STD-461 test completed for one of our solutions. They are very quick to turnaround quotes which is important in our competitive market. Their company is very well respected in the industry (which is important) and they provide great customer support from sales to engineering. We plan to utilize them again in the future and appreciate all of DNBs support with our unique programs.

I really enjoyed my experience at DNB. My company performs ESS (Environmental Stress Screening) testing at DNB. The personal at DNB is very friendly and helpful. The best thing I like about testing at DNB is that they have an open lab atmosphere were I can go in and witness the testing myself if need be, or I can take as many pictures as necessary to capture the test set up clearly for test reporting purposes. I highly recommend using DNB for your Environmental or Qualification Testing needs.

Been going there from the beginning. Great service! Hard working! They do everything they can to help and support you. Through thick and thin of difficult problems they are there for you. I think I've spent. half my professional life there. I highly recommend them for EMI and Lightning testing. Sounds like Commonwealth is closing?
