Testing

ISO 26262 defines the probabilistic metric for random hardware failures (PMHF) as the average probability of a violation of a safety goal associated with a failure over a vehicle’s lifetime and architecture metrics. In this article, we propose a method to calculate the PMHF and expand the application to redundant subsystems that are not adequately described in the standard.

Design plans, engineering drawings, production procedures, safety memoranda, and marketing strategies can significantly help or hurt a manufacturer or product seller, especially in the event of product liability litigation.

It is no trivial matter to properly interpret system level test results on high-speed boards. Board manufacturers (OEMs) assess the ESD robustness of their system by means of gun testing, not always in accordance with the IEC standard.

This article describes how the principles of laboratory testing of electrical noise impairment can be followed in the automotive sector to dramatically reduce the manufacturer’s development time and effort.

Automobiles present a very harsh environment for the electrical and electronic devices incorporated into them. Two well-established industry standards that define a wide range of electrical disturbance tests are ISO-7637-2 and ISO-16750-2.

The market for automotive vehicles is growing rapidly in China, especially the market for passenger vehicles. This article provides an overview of the general regulations and new rules that will come into effect.

Verification of electrical safety testing equipment is a procedure that is often overlooked by manufacturers. Running test verification is crucial to ensuring that a safety device will properly detect product failures. While the task of setting up a test verification can seem daunting, it’s a simple matter of having the necessary equipment and procedures in place so that the process is easy to follow.

Why hasn’t multi-burst testing to simulate lightning been more widely done? And why hasn’t it made its way into standards?

It is a dramatic understatement to say that the world of electronic devices continues to go more portable. The mantra of smaller, lighter, and faster shows itself through the myriad of devices we use as we move through our world outside of traditional work and home environments.

This article will summarize the major changes of the new revision of ISO/IEC 17025-2005, present the new outline of the standard and will discuss the new concept of a “risk-based” approach of implementing requirements.
