HALT and HASS tests
Ensure the robustness and reliability of your products
What are HALT and HASS tests?
HALT testing: Exploring the limits of your products
HALT testing involves subjecting your products to a series of thermal and mechanical tests right from the initial design phase. The aim is to quickly detect design weaknesses and identify potential defects that could arise during qualification or after marketing.
Key benefits of HALT testing:
- Early identification of design weaknesses.
- Improved equipment robustness.
- Reduced development times.
- Accelerated time to market.
HASS testing: Validate your manufacturing processes
HASS testing, carried out in production, allows you to subject all or part of your equipment to thermal and mechanical stresses with severity levels derived from the results obtained during HALT testing. These tests highlight defects related to manufacturing processes and variations in component supply.
Key benefits of HASS testing:
- Elimination of latent manufacturing defects.
- Validation of manufacturing processes.
- Improved reliability of delivered products.
Which sectors are concerned by these tests?
Automotive and transport
Aeronautics and defence

Key stages in HALT & HASS testing
A comprehensive approach to the product life cycle
HALT and HASS tests have a direct impact on the three phases of your products' life cycle, as illustrated by the bathtub curve model:
- Start-up phase: Detection and elimination of early defects, resulting from design or manufacturing.
- Maturity phase: Stabilisation of the failure rate, limited to incidents of use.
- Wear phase: Identification of any weaknesses linked to the age or wear of components.
Measurable benefits for your operations
By adopting a strategy based on HALT and HASS tests, you can benefit from the following advantages:
- Improved product quality and reliability.
- Reduced development costs and time-to-market.
- Fewer service calls.
- Improved customer satisfaction.
- Optimised design margins.
