Resonate Testing supports altitude and combined temperature-altitude testing for aerospace, defence, space, battery, packaging and electronic products using customer-defined requirements and recognised standards including RTCA DO-160, MIL-STD-810, IEC/EN 60068 and UN 38.3.
Resonate provides altitude and temperature-altitude testing services for aerospace, defence, battery, electronics, packaging and advanced engineering programmes. Our altitude testing UK and altitude testing Ireland capability supports qualification, verification and reliability evidence through controlled low-pressure and combined environmental testing. Combined with vibration and shock testing services, it offers a coordinated route for products exposed to flight, high-altitude operation or air transport conditions.
Altitude testing exposes products to reduced atmospheric pressure so teams can understand how equipment behaves during flight, high-altitude operation, air freight, storage or rapid pressure change.
Low-pressure simulation: Recreates the reduced pressure conditions associated with altitude exposure.
Temperature-altitude testing: Combines pressure and temperature to reveal issues that may not appear in single-condition tests.
Aerospace and defence use: Supports avionics, airborne systems, electronics, electromechanical assemblies and high-reliability equipment.
Battery and packaging relevance: Supports UN 38.3 altitude simulation, air transport and shipping-related pressure exposure requirements.
Functional checks: Allows agreed electrical, telemetry or operational checks before, during or after exposure.
Evidence generation: Produces pressure, temperature, observation and reporting outputs to support qualification, compliance or development decisions.
Altitude requirements can come from aerospace, defence, battery, packaging or customer-specific specifications. Whether you are validating an engineering model, preparing for qualification, planning acceptance testing or checking transport robustness, an early engineering review can help identify the practical route.

Altitude testing is usually tailored to the product, operating environment and compliance route. Requirements may reference RTCA DO-160 Section 4, MIL-STD-810 low pressure methods, IEC/EN 60068 temperature-altitude tests, UN 38.3 battery transport testing or a customer-defined profile.
The objective is not simply to reach a target altitude. The objective is to generate evidence that is relevant to the equipment, use case and acceptance process. Pressure level, temperature range, dwell periods, ramp rates, functional monitoring and reporting requirements should be reviewed before testing begins.
Combined temperature-altitude testing can be especially useful where electronics, seals, enclosures, batteries or assemblies may respond differently when low pressure and temperature are applied together.
Early review of applicable standards can reduce rework, improve traceability and help ensure the resulting test evidence aligns with stakeholder expectations.
Resonate Testing provides engineer-led altitude and temperature-altitude testing for aerospace systems, defence equipment, avionics, electronics, batteries, packaging and high-reliability assemblies across the UK and Ireland. Programmes can include low-pressure exposure, combined temperature-altitude profiles, air transport simulation and qualification support depending on the agreed specification.
The laboratory supports development, validation and compliance testing for products exposed to flight, high-altitude operation, reduced pressure, storage or transportation environments. Test activity can be planned against recognised standards such as RTCA DO-160, MIL-STD-810, IEC/EN 60068 and UN 38.3, as well as customer-defined pressure and temperature profiles.
Repeatedly moving the test item between defined hot and cold temperatures to reveal issues such as expansion, contraction, fatigue or changing operating conditions.
