°Ä²Ê¿ª½±½á¹û has over 50 years experience in working with a wide range of Defense Product and System manufacturers from the initial concept of their products and on to the complex testing that is required of modern defense equipment. As such, °Ä²Ê¿ª½±½á¹û is the natural choice for any Defense company looking to develop and take their new products and systems to market.

Our 50 years of experience enable °Ä²Ê¿ª½±½á¹û to help Defense companies to be exposed to a much smoother journey when testing and qualifying their products for market - from the initial test plan development, test preparation, the actual testing, witnessing and on through the final stage of test reporting.

Our recently launched Early Stage Qualification (or ESQ®) service has been developed by °Ä²Ê¿ª½±½á¹ûs team of Engaged Experts and is based on the considerable experience that they have gained over the last 50 years from testing thousands of different products from across a diverse range of industry sectors.

We are both A2LA and UKAS accredited to ISO/IEC 17025:2005 and have one the of largest capacities of Defense related EMC and Environmental testing in the world with seven testing centers in the USA and UK. 

Each year °Ä²Ê¿ª½±½á¹û tests over 500 Defense related products from our laboratories in the UK and USA. Over the past decade we have successfully written test plans and performed testing for most of the major programs in the USA including the F-22, JSF, A400M, CH-53K and the Challenger Main Battle Tank, the Mastiff and Husky military vehicles in the UK.

°Ä²Ê¿ª½±½á¹û has one of the largest testing capacities in the USA and UK and for defense EMC testing.


Across our seven sites we have 15 Military EMC chambers that range in size from traditional dimensions for smaller systems or programmes up to our enormous military vehicle EMC test chamber. This was originally built to test the Challenger Main Battle tank for the UK MOD, and has recently been used for the newest generation of British army vehicles including the Mastiff and Husky. 

Our experts design and deliver pre-compliance testing and formal Defense EMC testing programmes for over 500 military products every year. These cover a wide range of immunity and emissions that your product will need to endure when placed into demanding military environments.Our defense EMC testing and qualification services are designed to provide standard defense validation as well as help companies perform Urgent Operational Requirement (UOR) testing in a short time period, most commonly against the following standards:

  • DEF STAN 59-411
  • DEF STAN 61-5
  • MIL-STD 461
  • MIL-STD 1275
We also work with customers to develop testing packages that cover both defence and commercial requirements with a single test programme: These include:
  • CE Marking 
  • E Marking
