MIL-STD-461 EMC testing in the UK covers the US Department of Defense requirements for the electromagnetic emissions and susceptibility of military equipment. UK suppliers meet it when they sell into US programmes or when a contract names it, often alongside or instead of the UK equivalent, DEF STAN 59-411.

Match the lab to the revision your contract calls for and to the test methods it lists, such as conducted and radiated emissions and susceptibility. Field strength capability, chamber size and the ability to test large or installed equipment often decide the choice. Some consultancies on this page write test plans and procedures rather than test.

Use the filters to narrow by accreditation and facility type, then shortlist and send one enquiry to all of them.

Frequently Asked Questions

What does MIL-STD-461 cover?

Requirements and test methods for controlling electromagnetic interference from, and susceptibility of, military equipment and subsystems.

How is it different from DEF STAN 59-411?

MIL-STD-461 is the US Department of Defense standard; DEF STAN 59-411 is the UK Ministry of Defence equivalent. Your contract will name which applies.

Which revision applies?

The one your contract names. Revisions differ, so check the lab's schedule lists that revision and the test methods you need.

Can a consultancy help before testing?

Yes. Some write the EMC control and test plans and support trials, and can help choose and manage the test lab.
