Probably the most important attribute of any product, such as a car, is its durability. Obviously a products performance is essential, such as acceleration, handling, carrying capacity, comfort or fuel efficiency, but this is only a small part of the equation. Ask yourself if you would buy your next car if it only lasted a short time and you couldn’t sell it on to a second owner.
This gives an interesting dilemma to the test engineer. The design or marketing requirement is to have a long life, warranties now exceed 3 years, user life in excess of 10 years. But there is a huge pressure from companies to reduce the design and development period, often now less than a year.
How then do we prove a product to be durable? Can we accelerate any testing inside the one year development cycle, but still include all the correct inputs from a 10 year life? More importantly to also prove all of the production will be durable?
This presentation will outline a little of the history of accelerated durability testing, and some of the modern processes being used for the accurate acceleration of the development and testing of new products.
