DNB Engineering

DNB Engineering is a test laboratory in California. It tests electronic parts and systems for aviation, space, defence and other industries. The lab checks that equipment keeps working near other electronics, in lightning and in harsh conditions. Alwyn Broaddus founded the company, and the family has owned and run it since 1979. The head office is in Fullerton, California. It also has sites in Anaheim, California, and Coalville, Utah.

The lab does several kinds of testing. EMC and EMI testing checks electromagnetic compatibility and interference. HIRF testing covers high intensity radiated fields. The lab also tests for direct and induced lightning effects, environmental stress, product safety and regulatory approval.

The company names many test standards. These include MIL-STD-461, MIL-STD-464, MIL-STD-704, MIL-STD-810 and RTCA DO-160. It also lists SAE ARP 5412 to 5416, MIL-STD-1399, MIL-STD-1275 and MIL-STD-202. For commercial approvals, it tests to FCC, UL, CE Mark and CSA requirements.

The lab is accredited to ISO/IEC 17025 and is NEMKO authorized. It appears on the Defense Supply Center Columbus laboratory suitability listing. It also offers GR1089 NEBS and Bellcore testing.

DNB says it has supported most major aerospace and defence prime contractors in the United States, along with hundreds of their subcontractors. It says it has taken part in just about every major military, aerospace, automotive and commercial program in the last 40 years.

The company also gives engineering and design help. Its engineers can solve problems found during testing and advise in the early design stage of a product. The site also notes a custom line impedance stabilization network product.

DNB takes part in industry events. The site notes appearances at Space Tech Expo in California and at the Space Symposium. It lists a seminar on induced lightning susceptibility held with Ophir EMC and EMCmini in Anaheim and Fullerton. A news item mentions a strategic collaboration with the National Radio Research Agency.
