Resonate Testing supports product validation, qualification, reliability assessment and compliance programmes using controlled temperature, cyclic temperature, combined temperature and humidity, and rapid thermal shock exposure for customers across the UK, Ireland and beyond.
Resonate provides environmental testing services for aerospace, defence, automotive, electronics, energy and advanced engineering programmes. Our temperature testing, temperature cycling, combined temperature and humidity, and thermal shock capability helps teams verify performance, expose weaknesses and build reliable evidence for demanding operating environments.
Temperature, humidity and thermal shock testing expose products to controlled environmental conditions so teams can understand how materials, electronics, assemblies and complete systems behave before release, qualification or customer acceptance.
Temperature testing: Verifies performance, storage tolerance and functional behaviour at defined hot and cold conditions.
Temperature cycling: Repeatedly moves hardware between temperature limits to identify fatigue, expansion, contraction and intermittent faults.
Combined temperature and humidity: Assesses resistance to damp heat, condensation risk, corrosion drivers, insulation changes and moisture-related degradation.
Thermal shock: Transfers products rapidly between hot and cold environments to reveal cracking, seal failure, delamination or assembly stress.
Functional checks: Allows agreed electrical, mechanical or visual inspections before, during or after environmental exposure.
Evidence generation: Produces measurements, observations and reporting to support design, qualification and supplier acceptance decisions.

Ready to plan your environmental test campaign? Send your temperature, humidity, cycling or thermal shock requirement, specification or drawings for engineer review and receive guidance on setup, monitoring and programme readiness.
Product programmes rarely begin with a perfect test specification. Whether you are validating a prototype, qualifying a design, investigating a field issue or preparing for customer acceptance, an early engineering review can help identify the most practical temperature, humidity or thermal shock route.
Share your product description, operating environment, temperature limits, humidity exposure, cycle count, dwell times, ramp-rate needs, functional checks and programme objectives. Resonate Testing can review setup, monitoring and reporting expectations before quotation.

Environmental test profiles are rarely defined by a single factor. Programmes often combine customer specifications, product use cases, industry standards and known field conditions to define temperature limits, humidity levels, cycle count, transition rate and acceptance criteria.
The objective is not simply to run a chamber cycle. The objective is to generate evidence that is relevant to the product, operating environment and acceptance process. Temperature set points, humidity exposure, ramp rates, dwell periods, recovery checks, functional monitoring and reporting requirements should therefore be reviewed before testing begins.
Programmes may reference IEC 60068 methods, MIL-STD-810 environmental procedures, RTCA DO-160 for airborne equipment, automotive or defence specifications, or a customer-defined profile. Early review helps align the test method with the evidence the reader, customer or certifying stakeholder needs.
Early review of applicable standards can reduce rework, improve traceability and help ensure the resulting test evidence aligns with stakeholder expectations.

Environmental testing evaluates how products behave when exposed to hot, cold, damp, cyclic or rapidly changing temperature conditions. Typical objectives include assessing thermal stress effects, moisture sensitivity, material stability, assembly integrity, functional performance and reliability during realistic environmental exposure.
Test planning is normally based on the specific project and product requirements, including temperature limits, humidity levels, cycle count, ramp rates, dwell periods, thermal shock transfer expectations, monitoring requirements and reporting outputs. Applicability should be confirmed for the exact product, materials and programme requirements before testing begins.
Resonate Testing provides engineer-led temperature, temperature cycling, combined temperature and humidity, and thermal shock testing for aerospace systems, defence equipment, electronics, batteries, materials and mission-critical assemblies across the UK and Ireland.
The laboratory supports development, validation and compliance testing for products that must tolerate hot, cold, damp, cyclic or rapidly changing environments. Test activity can be planned against recognised standards, customer-defined profiles and real operating, storage or transport conditions.
Successful environmental testing requires more than reaching a target set point. Monitoring and verification may include control sensors, product-mounted thermocouples, humidity measurement, customer telemetry, electrical interfaces, visual inspections, pre-test checks and post-test observations. Tolerances, ramp rates, dwell times, recovery periods and abort criteria should be reviewed before the campaign begins.
For high-value equipment, the setup approach is central to the quality of the test. Dimensions, mass, orientation, cable routing, condensation risk, sensor locations and functional access should be reviewed early so the item can be monitored safely and exposed as intended.
Early engagement helps identify chamber fit, fixture needs, stabilisation criteria, monitoring requirements and practical risks before the test campaign starts.

Temperature testing exposes hardware to defined hot or cold conditions to verify performance, storage tolerance, material behaviour and functional stability.
Temperature limits define the hot and cold set points the product must experience. They should be reviewed with the applicable standard, customer specification, use case and acceptance criteria before testing begins.
Temperature cycling repeatedly moves hardware between hot and cold limits to reveal fatigue, expansion and contraction effects, intermittent faults and weaknesses at interfaces.
A cycling profile should identify the temperature limits, number of cycles, ramp rates, plateaus, dwell times, monitoring requirements and any functional checks needed during the test.
Thermal shock testing rapidly transfers a product between hot and cold environments to stress materials, seals, solder joints, coatings and assemblies exposed to sudden temperature change.
Dwell time is the period a product remains at a specified temperature or humidity condition once the chamber or product has reached the required point.
Ramp rate is the speed at which the chamber or product moves from one temperature condition to another during a profile.
Temperature and humidity exposure can reveal faults that are difficult to find at room conditions, including intermittent electrical failures, seal leakage, condensation sensitivity, coating breakdown, adhesive weakness, material distortion, cracking, corrosion and dimensional change.
Thermal shock is especially useful where rapid transition is a credible risk. It can stress interfaces, solder joints, seals, potting compounds, enclosures, glass-to-metal joints and dissimilar materials that expand and contract at different rates.
Products often need more than one environmental exposure. Coordinating temperature testing, temperature cycling, combined temperature and humidity, and thermal shock within one campaign helps reduce handover friction, align documentation and keep the engineering review connected across the full programme.
For projects that also need complementary environmental testing, review the full product environment before finalising the campaign sequence.
Outputs are agreed before the test so the evidence matches the programme need. A typical package may include:
Recorded temperature, humidity and agreed telemetry data
Plots showing the achieved profile, ramp periods, dwell points, humidity exposure and thermal shock transitions where applicable
Observations from setup, test execution and post-test review
Photographic evidence where agreed
Confirmation of functional checks completed during the profile
An agreed test report or data pack aligned to the quotation scope
