Highly Accelerated Stress Screening (HASS) Test
-
HASS consists of high and low temperature and 3 axis vibration testing performed either individually or in combination.Highly accelerated stress screening is a technique for identifying process flaws in equipment during production. HASS subjects equipment to overstress conditions but at a level which does not affect design life.For assistance in designing a HASS test program contact the laboratory.

Environmental Stress Screening
ESS
-
Environmental stress screening (ESS) is also known as Burn-in, AST (Accelerated Stress Testing), HALT (Highly Accelerated Stress Test), or HASS (Highly Accelerated Stress Screening). Whatever the name, the idea is the same: create a test program that allows you to eliminate the infant mortality of your product.

HALT/HASS Testing
HALT HASS Chamber
-
AST applies stresses (such as temperature and vibration) to products well beyond its normal use environment. This type of testing is done to determine product operating and destruct limits. These stresses are applied as the product is functionally tested and continuously monitored for failures.Highly Accelerated Stress Testing (HALT) and Highly Accelerated Stress Screening (HASS) are two types of accelerated stress testing. These types of tests are commonly used to eliminate design problems, helping to develop a robust, mature product prior to market introduction. It can also be used to screen out infant mortality issues prior to shipment.

Load Testing vs. Stress Testing
-
A load test is a planned test to perform a specified number of requests to a system in order to test the functionality of the system under specific levels of simultaneous requests. A load test ensures that a web system is capable of handling an expected volume of traffic, and therefore is sometimes referred to as volume testing. The goal of a load test is to prove that a system can handle the expected volume with minimal to acceptable performance degradation. The threshold of acceptable performance degradation must be defined by the testers as some value considered acceptable to the end user so that users will not bounce from the site.
