Is your test software the goose that has laid its golden eggs or is your software misbehaving? Does it run amok? The purpose of this article is to provide an understanding of the software validation requirements, the validation rationale, and suggest independent tools that will allow you to develop your own test software validation process.
This article explains the development process of a proficiency testing programme that is suitable for electrical and mechanical safety tests. The process for testing the homogeneity and stability of specimens is also discussed.
This article discusses the IEC 60601 Amendments Project, for Medical Electrical Safety, some of the changes to the General and Collateral Standards of the Project, and their impact on manufacturers. The future of the 60601 series of standards is also discussed.
Confusion over ESD flooring resistance terminology and requirements abounds, leaving many in the dark and creating potential risks. This article helps to clarify this complicated issue so that you can work to mitigate the problem.
The standards development and revision process can appear to be a lot like consulting some hallowed oracle with edicts or directives that cannot be questioned.

The European Commission's Low Voltage Directory (LVD) legal obligations vary for economic operators, with most falling upon manufacturers. The new LVD Guide offers interpretation and instruction on these obligations, clarifying when importers and distributors might take on manufacturer responsibilities among other issues.
In its current form, IEEE Std 149 “IEEE Standard Test Procedures for Antennas” is a marginally useful document. While the standard is a good source for interesting and pertinent information, the document has not undergone a significant update since 1979. The changes to the new version of the IEEE Std 149 will make the document an essential reference in any laboratory that conducts antenna measurements.
Protection from high-altitude electromagnetic pulse (HEMP) and intentional electromagnetic interference (IEMI) is an important consideration to the design of modern electronic systems, especially those that control critical infrastructures.
