Highly Accelerated Stress Testing (HAST) Services
Need faster, more reliable humidity testing for semiconductors and packaged devices? Transform weeks of testing into days with Element's HAST services. Our expert-designed test plans ensure product safety while accelerating time to market. Get A2LA-accredited, ITAR/EAR-compliant testing for commercial and government applications—with comprehensive data and reduced costs through our customized approach.
What is Highly Accelerated Stress Testing (HAST)?
HAST testing is an advanced environmental simulation method that provides a more efficient alternative to traditional humidity testing, most commonly used for testing electronic components, semiconductors, and assemblies. By elevating temperatures and increasing pressure, Element simulates long-term humidity conditions to observe the same failure mechanisms, in days rather than weeks.
Our testing supports multiple applications including semiconductor reliability, packaging validation, transportation testing, and shelf-life programs. We provide efficient and reliable testing for your non-hermetic and packaged devices, delivering comprehensive safety data through our accredited facilities.

Methods and solutions offered
Methods and solutions offered
We develop customized test plans tailored to your specific product requirements and development stage. Our methodology supports every phase of your product lifecycle, from initial research through design validation to prototype evaluation and final qualification. By combining elevated temperatures and pressure with precision monitoring, we deliver reliable results that help you make informed decisions about your product's performance and durability.
Our labs help determine reliability of non-hermetic, packaged and solid-state devices in a variety of humid environments. Along with temperature and humidity conditions, a bias (DC voltage – continuous or cycled) can accelerate the penetration of moisture, to provide results in less time.

Frequently asked questions
How does HAST testing differ from traditional temperature-humidity testing?
Unlike traditional temperature-humidity testing, HAST testing uses elevated pressure in addition to high temperature and humidity to accelerate moisture ingress and chemical reactions. This allows manufacturers to simulate years of field exposure in weeks rather than months enabling faster reliability validation and design refinement without compromising the integrity of failure mechanism data.
