HALT & HASS Testing
Highly Accelerated Life & Stress Screening
DynaQual offers comprehensive HALT, HASS, and lifecycle testing using the Qualmark (Espec) Typhoon 4 Inferno HALT chamber, with capabilities including rapid thermal ramping, N₂ purge, combined multi-axis vibration/thermal environments, and extended lifecycle testing. HALT testing is used to rapidly identify design weaknesses and true operating margins by intentionally overstressing a product early in development, reducing reliability risk, time to market, and costly failures in the field. HASS testing is used to screen out latent manufacturing and process defects by applying controlled overstress during production, improving outgoing quality while reducing early life failures and warranty risk. N₂ purge clean air is used to evaluate aerospace and sensitive hardware under repeated temperature extremes while protecting materials and electronics from oxidation, moisture, and contamination.

Shock Testing
Classical, pneumatic, and drop shock
DynaQual provides shock testing using two primary methods: electrodynamic (ED) shaker testing for controlled, repeatable pulses, and pneumatic shock testing via VST (Emerson) equipment for high-g, high-fidelity shock environments. These services support military, aerospace, and commercial applications by identifying structural weaknesses, validating design margins, and confirming compliance. Classical Shock on the ED shaker applies precisely controlled shock pulses to verify structural integrity and functional robustness against industry and military shock requirements. Pneumatic Shock on the VST machine generates high-g, short-duration shock pulses that realistically replicate severe impact events for military and aerospace validation. Drop Testing on the Lansmont PDT-300 performs controlled flat, edge, and corner drops simulating real-world handling impacts and verifying compliance with ISTA and carrier requirements.

Vibration Testing
Sine, random, and combined-environment vibration
Electrodynamic shaker testing for sine, random, sine-on-random, and random-on-random profiles. Used to qualify electronics, downhole assemblies, and packaged systems against transportation, operational, and design-margin vibration environments.

Package Testing
Engineer-driven package and transportation testing
DynaQual provides engineer-driven package testing to validate packaging performance against distribution hazards. Programs support ISTA, MIL-STD, ASTM, UPS, FedEx, and other carrier- or customer-specific specifications for commercial and defense supply chains. Drop Testing delivers precise, repeatable flat, edge, and corner drops that simulate real-world handling impacts using the Lansmont PDT-300 precision drop tester. Vibration Testing on calibrated electrodynamic systems simulates truck, air, and rail transportation environments. Thermal Testing conditions packages at temperature extremes and transitions. Together these programs provide data-driven insight into package durability, damage risk, and design margin to optimize packaging before production.
