In sectors such as defence, medical, marine, rail and industrial automation, systems usually need to comply with strict certification standards. Failure to meet these requirements can delay deployment, increase costs or even prevent systems from being approved entirely.
For engineers and sourcing teams, selecting the right certified computing platform can significantly reduce project risk, accelerate approval processes and improve long-term reliability.
Pre-Compliance versus Full Certification
Pre-compliance testing is carried out during the development phase to identify potential compliance issues before a product enters formal certification testing.
Facilities such as EMC chambers, vibration rigs and thermal test environments, enable engineers to assess how a system performs against relevant standards early in the design cycle. This allows problems such as excessive electromagnetic emissions, poor shielding, mechanical weaknesses or thermal instability to be identified and corrected before formal approval testing begins. Steatite has in-house testing facilities to support this process.
The key advantage is risk reduction. Formal certification testing is expensive and failures can cause significant project delays, redesign costs and programme disruption.
By carrying out pre-compliance testing first, manufacturers and system integrators gain confidence that the hardware is likely to pass final certification. Purchasers benefit from reduced technical risk, shorter development timelines and more predictable deployment schedules. Total Cost of Ownership (TCO) and Obsolescence Management (OM) are better managed due to:
- Reduced re-testing
- Fewer field failures
- Lower maintenance costs
- Avoided redesigns
- Controlled BOMs
- Revision locking
- Managed last-time-buy strategies
Certification Is About More Than Compliance
A certified computer is more than just a rugged PC. Certification demonstrates that a system has been tested against recognised standards covering factors such as:
- Shock and vibration
- EMC and EMI performance
- Electrical safety
- Temperature tolerance
- Fire and smoke compliance
- Reliability in harsh environments
For project teams, this matters because the computer often becomes part of a larger certified system. If a subsystem fails compliance testing late in development, the cost and schedule impact can be substantial.
Using pre-certified or certification-ready computing hardware helps reduce integration risk and simplifies wider system qualification activities. It can also reduce the amount of additional testing required at project level.
Defence: Reliability Under Extreme Conditions
Defence applications place unique demands on embedded computing. Systems may operate in mobile platforms, exposed outdoor environments or electrically noisy installations where failure would be catastrophic. Our previous blog looks in more detail at the differences between commercial and military grade computing.
Military-grade computers are commonly required to meet standards such as MIL-STD-810 or DEF STAN 00-35 for environmental factors and MIL-STD-461 or DEF STAN 59-411 for EMC performance.
For engineers, these standards influence enclosure design, thermal management, connector selection and internal component layout. Integrators also need to consider supply continuity, lifecycle support and configuration control, particularly for long-running defence programmes.
Additionally, TEMPEST standards are designed to protect sensitive electronic systems from compromising electromagnetic emissions that could be intercepted and exploited for intelligence gathering. TEMPEST-compliant computers and systems are engineered to minimise unintended RF emissions through specialised shielding, filtered power designs and carefully controlled enclosure construction.
Selecting hardware that has been designed with TEMPEST considerations from the outset helps reduce integration complexity and lowers the risk of costly redesigns during security accreditation processes.
Organisations working with classified or mission-critical data increasingly view TEMPEST compliance as more than just a security requirement. It’s now considered as an essential part of wider system assurance and operational resilience.
Steatite’s comprehensive range of military-grade computing & PNT solutions offer options that are fully certified by recognised test houses, saving customers valuable time and resources.
Medical: Managing Safety and Long-Term Stability
Medical systems require a different approach. Here, certification is closely linked to patient safety, system stability and long-term reliability.
Devices used in imaging, diagnostics and laboratory equipment often need to comply with standards covering electrical safety, EMC and risk management. Even relatively small hardware changes can trigger validation requirements within regulated medical environments.
This is why long-term product availability is critical. Frequent hardware revisions or component obsolescence can create expensive requalification exercises for OEMs.
High-performance GPU systems are becoming increasingly significant in medical imaging, supporting AI-assisted diagnostics. This is escalating the importance of thermal stability even further.
At Steatite, we focus heavily on long-life industrial computing platforms and controlled configuration management. This supports medical device manufacturers in maintaining consistency throughout the product lifecycle. View our solutions for medical computing.
Marine: Built for Offshore and Naval Environments
Marine computing applications demand systems that can operate reliably in some of the harshest conditions encountered by electronic equipment. Salt-mist, constant vibration, humidity, fluctuating power conditions and extreme temperatures all place significant stress on embedded computers and network infrastructure. Systems often need to comply with marine certification standards such as Det Norske Veritas (DNV), Marine Equipment Directive (MED) or IEC 60945.
Long-term serviceability and lifecycle support must be considered for systems operating in remote or difficult-to-access locations where downtime is costly. Using certified marine-grade computers can simplify integration, reduce approval complexity and improve operational reliability over the lifetime of the platform.
We support marine and offshore projects with rugged marine computing platforms for bridge control to ROV systems. These are engineered to withstand the environmental and operational challenges faced across commercial maritime, offshore energy and naval applications.
Rail: Meeting EN50155 and Transport Standards
Rail applications present a combination of environmental, electrical and operational challenges. Onboard systems must withstand vibration, fluctuating power conditions and wide temperature ranges while maintaining continuous operation.
Standards such as EN50155 and EN50121-3-2 are commonly required for rail-certified computing systems. These, and other standards, cover:
- Environmental factors (EN 50155)
- Hardware durability (EN61373; EN50121-3-2; EN50121-4)
- Fire and smoke safety (EN 45545-2)
- Cybersecurity (IEC 62443; TS50701)
- Safety-critical systems (EN50126 – Reliability, Availability, Maintainability, and Safety (RAMS); EN50128; EN50129)
For project teams, selecting hardware already designed and tested for rail environments can dramatically simplify deployment. It reduces uncertainty during system integration and helps avoid costly redesigns later in the programme.
Steatite supplies rugged computers and fanless embedded systems certified for rail use. These include platforms designed for onboard CCTV, passenger information systems and edge processing applications.
Importantly, our engineering teams also support customisation and system integration where projects require application-specific I/O, power conditioning or mechanical modifications.
Industrial: Reducing Downtime and Engineering Risk
Industrial automation environments may not always require formal certification to the same level as defence or rail, but reliability remains critical.
Dust, vibration, temperature extremes and continuous 24/7 operation can quickly expose weaknesses in commercial-grade hardware. A low-cost office PC may work during early development but become a reliability issue once deployed on the factory floor.
Industrial-grade fanless computers and rugged HMIs are designed specifically for these conditions, reducing maintenance requirements and improving system uptime.
For purchasing teams, it’s also important to evaluate supplier capabilities beyond the hardware itself. Areas such as BIOS control, long-term availability, pre-compliance testing, custom integration and through-life support all have a direct impact on total project cost.
Choosing the Right Partner
Certification affects far more than the computer alone. It influences project schedules, integration effort, testing costs, maintenance planning and long-term product support. While not every application requires formal certification, using certification-ready hardware even in less regulated environments can improve reliability and reduce long-term support costs.
That’s why selecting an experienced engineering partner is just as important as selecting the hardware itself.
At Steatite, we combine rugged computing hardware with in-house customisation and certification support capabilities. Whether customers require an off-the-shelf industrial computer, a modified COTS platform or a fully custom engineered integrated computer system, our focus is always the same: delivering reliable computing solutions engineered for real-world deployment in critical environments.
