Reliability engineers may suggest environmental stress tests. There are many types of tests in an RE's toolbox. We compare two types of commonly known tests that are used for design: ALT vs. HALT. What are the important distinctions between these two methods? What value do they each bring to design engineering? And how do they fit into other reliability test methods? Visit the website for additional links, downloads, and a venn diagram.
