Testing: Environmental

MIRA operates one of Europe’s largest and most comprehensive independent environmental testing facilities.

The facilities range from 180-litre environmental chambers to full-size vehicle climatic wind tunnels, together with both ambient and climatic vibration test facilities. The facilities are located at two UK sites, the main engineering centre at Nuneaton and a dedicated environmental test site established in 2000 – Quatro Park, located in Basildon, Essex.

High Quality Service and Accreditation

MIRA is ISO/IEC 17025 Accredited for environmental and vibration testing, and is staffed by engineers widely experienced in environmental testing and product development.

• Ambient and climatic three axis vibration
• Combined multi-axis vibration and environmental facilities
• Walk-in combined vibration and environmental chambers
• Component environmental chambers
• Thermal shock
• Dust chambers
• Corrosion
• Mechanical shock
• Airbag deployment (ambient and extremes of temperature)

Diverse Product Test Capacity

The range of products that can be tested is significant and covers the automotive, aerospace, defence, rail and medical industries.

Products tested include components such as:

• Automotive instrument clusters
• Radios/CD players/DAB radios
• Electronic climate control
• Interior trim components
• Coolant systems
• Powertrain components
• A wide range of components and assemblies from other industries can be tested under environmental conditions

Test Programmes

In addition to providing an environmental testing service, undertaking tests to customer test specifications or International Standards and assisting in the product development process, advice on the generation of full component Design Verification (DV) and Product Validation (PV) test programmes can be provided to customers if required for a wide range of products.

Teardown and Analysis Service

To investigate the condition of a component upon the completion of a test a full teardown analysis service is available. This is particularly useful for electronic components where any physical damage to both the assembly and the circuit boards resulting from the test is investigated and reported. The dimensional stability of a product after undergoing an environmental test can also be assessed using a CMM system.
