How we work
01
Collect requirements
We gather the contract's environmental and EMI requirements, the MIL-STD-461 revision it calls up, the platform installation and the life-cycle profile.
02
Tailor and plan
We tailor methods, procedures and levels, sequence tests to share hardware, and write plans and procedures for approval.
03
Pre-compliance
Development units are checked for emissions and susceptibility, and mechanical and thermal risks are analysed in simulation.
04
Formal testing
We coordinate the accredited lab, attend test runs, and handle anomalies and retests with your team.
05
Close out
Reports are reviewed against the plan and any deviations and waivers are documented for your customer.

MIL-STD-461H: what changed and which revision applies
MIL-STD-461H was issued on 17 April 2026 and supersedes MIL-STD-461G, issued on 11 December 2015. It is a targeted revision, not a rewrite: CE101 applicability is extended from 10 kHz to 20 kHz for surface ships and submarines, test equipment options for CS101 change, and RE101 procedural notes are revised. In Compliance Magazine and EMC Directory describe it as a revision focused on clarification and test consistency.
Many programmes still specify MIL-STD-461G on contract, and the applicable revision is set by the contract and the procuring activity, not by the publication date. We build the applicability matrix from the revision your contract names. Where a programme is moving to 461H, we mark which procedures and set-ups change. In Compliance Magazine's review suggests labs update their procedures within six months of release, so we confirm which revision your chosen lab is set up to run.
Indigenisation means qualification testing
India's 6th Positive Indigenisation List, notified on 18 August 2026, added 405 items worth about ₹3,070 crore, mostly line-replaceable units, sub-systems and spares, taking the six lists to 5,417 items, as reported by Defence Standard. Each indigenised LRU or sub-system needs qualification evidence: environmental testing to tailored MIL-STD-810H methods, EMI testing to the MIL-STD-461 revision on contract, and the test documentation the inspecting authority expects.

Frequently asked questions
Do you have your own accredited MIL-STD test lab?
No. We plan, prepare and support testing, and the formal qualification runs at an accredited third-party laboratory chosen with you. Our role is to make sure the equipment, procedures and test set-up are ready so lab time is spent on passing runs, not debugging.
What is MIL-STD-461 pre-compliance testing and why do it?
Pre-compliance is informal testing on development hardware, using bench equipment, LISNs, current probes and near-field probes, to estimate margin against the MIL-STD-461 limits in your contract. It finds emissions and susceptibility problems while design changes are still cheap, which reduces failed runs and retests at the formal lab.
What changed between MIL-STD-461G and MIL-STD-461H, and which do we test to?
MIL-STD-461H, issued on 17 April 2026, is a targeted revision of 461G (December 2015). CE101 applicability extends from 10 kHz to 20 kHz for surface ships and submarines, and CS101 test equipment options and RE101 procedural notes change. Many contracts still specify 461G. You test to the revision your contract or procuring activity names; if that is unclear, get it clarified before booking lab time.
Which MIL-STD-461 requirements apply to our equipment?
Applicability depends on the platform, the installation and the revision on contract. The applicability table in MIL-STD-461G and 461H (Table V in 461G) maps requirements such as CE102, CS114, RE102 and RS103 to Army, Navy and Air Force platforms, and the procuring activity can add or tailor requirements in the contract. We build the applicability matrix with you from those sources.
How is MIL-STD-810H tailoring done?
MIL-STD-810H expects tests to be tailored to the equipment's life-cycle environment rather than run at default levels. Part One describes the process: build a Life Cycle Environmental Profile, derive the environmental issues and criteria, then select methods, procedures and levels. The tailored plan is agreed with the procuring authority before testing.
Can you help with DO-160G for civil airborne equipment?
Yes. DO-160G covers environmental and EMI test procedures for civil airborne equipment and is often required alongside or instead of MIL-STD-810H and MIL-STD-461 on dual-use products. We plan the categories and sections that apply and coordinate testing in the same way.
How long does MIL-STD-461 testing take?
It depends on how many requirements apply, the number of operating modes and whether failures need fixing and retesting. One published guide from EMC Latest puts a typical MIL-STD-461 test programme at one to four weeks. Planning, procedures and pre-compliance before the lab booking usually decide whether the programme stays near the short end.
Do you only plan tests, or can you supply test engineers too?
Both. We take on test planning, pre-compliance and lab coordination as a scoped project under defence and aerospace testing, or place environmental and EMI test engineers in your team under your direction through hire test engineers.
