Product markings and labels provide information about the product, installation, and use. The markings and labels can also provide warnings to avoid hazardous energy transfer to a body part. The product safety aspects of markings for identification, ratings, functions, connections, and warnings are described.

In Part 2 of this two-part article, we’ll discuss the development and use of isolated bonding networks (IBNs).

In Part 1 of this two-part article, we’ll discuss the development of “grounding networks” and the shift to meshed structures to reduce damage from overvoltages. Part 2 will appear in our November 2020 issue.

The voltage based CDM classification has practically no meaning for IP qualification. In this article, we propose an alternative CDM qualification, which is based on a peak current criterion.

Traditionally, validation engineers of analog products have had to worry about one thing, their analog function. But with the advent of functional safety, the complexity in system design has increased, and functions once found only in digital devices are now making their way into analog devices as well. This leaves individuals with one question- how to validate?
