An example of an Elite HALT testOur Thermotron AST-35 HALT/HASS testing chamber coupled with our engineering team's unrivaled expertise are helping manufacturers across a wide range of industries evaluate their equipment for functional life and product design optimization.

Both HALT and HASS testing (each described in further detail below) have become industry accepted procedures and essential steps in meeting demands for high reliability and quality. By quickly discovering design flaws before an item is in full production, manufacturers save significant time and costs associated with test and validation, warranty replacement, and product liability litigation.

Highly Accelerated Life Testing (HALT)

The HALT procedure exposes products to increasing levels of stress that are closely related to that product’s operation. These stresses include temperature/rapid thermal transitions and vibration (both independent of and in combination with temperature stresses), among others. HALT can -- and should -- be used multiple times over the life of a product to achieve optimal product design. Benefits and processes include:

  • Discovering mechanical, electrical, functional and any other product design weak points
  • Finding design weaknesses early (when changes are the least costly), lowering development costs
  • Analyzing and correcting design weaknesses for product design optimization
  • Shortening time-to-market
  • Exposing problems caused by new manufacturing processes
  • Auditing product reliability caused by changes in components, manufacturing processes, suppliers, etc.
  • Combines six-axis vibration and temperature extremes

Highly Accelerated Stress Screening (HASS)

Harnessing data from HALT, a custom HASS test is then used to further reveal product defects not detected by other environmental stress tests. Benefits and processes include;

  • Overstressing test item to identify marginal or defective products (due to "latent" effects) before shipment
  • HASS test levels are identified during HALT and are established to compress test time without damaging the product or reducing its life
