HALT Testing Guidelines

Highly Accelerated Life Testing Guidelines
Today’s manufacturers are seeking ways to lower warranty costs, shorten product development cycles and increase reliability. This business pressure is driving the mandate for HALT testing (Highly Accelerated Life Testing) because it allows new products to get to market faster with reduced infant mortality and improved reliability.
HALT testing is usually conducted prior to design verification testing (DVT) and utilizes a process that uncovers failure modes and discovers the true operating margin of a product. Unlike traditional thermal chambers or Electrodynamic (ED) shakers, HALT testing systems are capable of producing a combined environment of rapid thermal changes and random vibration stresses that are crucial for improving product reliability.
Studies prove that up to 32% of failure modes can be missed without the combined environment (6 degree of freedom random shock vibration and rapid thermal cycling) available in a HALT system.
Qualmark's 2010 HALT Testing Guidelines, first released in 1998, define the process elements to successfully implement and perform HALT. It identifies technical responsibilities, facility and equipment requirements, and testing practice competencies. Adherence to this document will provide the fundamental guidelines to implement and operate a successful HALT. The document can be used as a basis for developing standards for professional organizations and businesses seeking to define effective HALT practices.
