Resonate Testing LTD supports global manufacturers through development, qualification, and certification evidence using IEC 60068 and customer-defined environmental requirements for UK, Ireland, and international programmes.
IEC 60068 is an international framework establishing uniform, reproducible environmental testing procedures. The framework assesses a specimen’s ability to operate within specified limits of temperature, pressure, humidity, and mechanical stress. Rather than defining the final product performance rules, the standard outlines structured parameters to compare sample configurations safely.

The IEC 60068 framework mandates a rigorous series of physical testing regimes designed to stress a product’s structure and electrical functionality under extreme simulation profiles.
To achieve compliance across international product specifications, specimens are subjected to specific environmental stresses:
| Standard / Guidance | Primary Focus | Typical Relevance |
|---|---|---|
| Test A: Cold | Steady-state minimum ambient | Zero structural cracking; parameter values remain within specimen specification limits |
| Test B: Dry Heat | Steady-state high temperature thermal aging and softening exposure | Zero melting or oxidation; insulation parameters must meet structural baseline requirements |
| Test Db: Damp Heat | Cyclic relative humidity injection matched with rapid thermal variations | Zero physical swelling or moisture absorption breakdown; high dielectric resistance |
| Test N: Change of Temp | Rapid temperature shock transfer across extreme thermal boundaries | Zero seal failure, leakage, or structural joint fatigue from differential contraction |
| Test Ea: Shock | Mechanical dynamic impact force delivery using precise acceleration pulses | Zero structural collapse or catastrophic material failure during stress cycles |
| Test F: Vibration | Multi-axis frequency sweep using sinusoidal or broadband random profiling | Zero dynamic resonance disintegration; electrical tracking remains fully continuous |
| Test M: Low Air Pressure | High-altitude vacuum simulation profiling for subassemblies | Zero enclosure expanding leaks; prevention of corona discharge or flashover |
| Test K: Corrosive Gas | Salt mist or active chemical media exposure profiling | Zero surface tracking deterioration; contact resistance must remain stable |
| Test Q: Sealing | Enclosure leakage check including container barrier evaluation | Zero fluid or moisture ingress under differential pressure gradients |
| Post-Test Recovery | Standardized stabilization hold under controlled 73%-77% RH guidelines | Performance metrics return completely back to normal ambient reference baselines |
Resonate supports engineer-led environmental testing covering temperature, humidity, thermal shock, altitude, vibration, shock, corrosion, rain, dust and ingress protection assessments.
Combined test programmes, functional monitoring, engineering review and detailed reporting are available to support qualification, reliability and compliance projects across aerospace, defence, automotive, rail, energy and industrial sectors.
| Specification | Capability |
|---|---|
| Temperature | -70°C to +180°C |
| Humidity | Up to 98% RH |
| Thermal Cycling | Customer-defined profiles |
| Vibration | Sine and Random |
| Mechanical Shock | Half-sine, sawtooth and bespoke pulse profiles |
| Corrosion Testing | Salt mist and cyclic corrosion exposure |
| Test Duration | Short-term screening to long-duration qualification programmes |
| Test Articles | Components, assemblies, batteries, electronics and complete systems |
A specimen whose hottest surface temperature rises by more than 5 K above the ambient air temperature once thermal equilibrium has been achieved under powered conditions.
The post-conditioning stabilization hold under controlled room parameters that allows a specimen to reach environmental equilibrium before final checks.
The exposure phase where a specimen is subjected to defined external stresses like freezing cold, heat, humidity, shock, or vibration
The preliminary environmental treatment applied to a specimen to stabilize its material properties before taking initial baseline measurements.
The temperature of the surrounding air inside the chamber or laboratory environment immediately surrounding the test specimen.
The specific component, subassembly, or equipment configuration undergoing environmental exposure trials.
Outputs are agreed before the test so the evidence matches the programme need. A typical package may include:
Book environmental validation testing for industrial components, electrotechnical equipment, enclosures, wiring assemblies and structural hardware. Use the contact route to share your standard, drawings, operating conditions and acceptance criteria for review.
