Highly Accelerated Life Testing is a screening technique in which relatively low numbers of stress cycles significantly outside the normal shipping, storage and operating envelope are applied to:
The use of such techniques:
The Screening Systems QRS 410-T is one of the latest generation of HALT chambers capable of applying up to 28 grms of random vibration in 6 axes simultaneously, whilst cycling the temperature between -60°C and +150°C, at rates of change of up to 60°C per minute. Thus the maximum stress screening for components in the minimum time is achieved.
Product Assessment & Reliability Centre Ltd. offers two levels of support for HALT:
Putting your product through a HALT process before embarking on a qualification test programme helps to find and resolve weaknesses in the design of a product. This will mean both time and money can be saved during qualification.
