What is……?

WELCOME, BIENVENU, WILLKOMMEN, BONVENON

Most people would call this a FAQ’s page.
The majority of Electrical and Electronic Engineers ( E&EEs ) think that the EMC fraternity has it’s own language and set of abbreviations, which they don’t understand. This page will answer questions like:

What is EMC ? – What is an OATS? – What is ESD?
What is BCI (Bulk Current Injection)? etc.
The answers to these and many other questions can be found on this page
.

You ask the question and we will get a professional EMC engineer to give you the answer. Put your details and the question in the form at the bottom of the page, and we will publish the answer.

The questions are split into three topics. These are 1) General Questions, 2) Test Facilities and Techniques and 3) Test Instrumentation


General Questions

What is Electromagnetic Compatibility (EMC)?

ANSWER
Electromagnetic Compatibility (EMC) refers to the ability of electronic and electrical systems, devices, and equipment to operate efficiently and without interference in their intended electromagnetic environment.

What is EMP?

ANSWER
An electromagnetic pulse (EMP) is a burst of electromagnetic radiation that can disrupt, damage, or destroy electronic equipment and systems. It can occur naturally, such as from lightning or a solar storm, or it can be generated intentionally as a weapon, known as a High-Altitude EMP (HEMP) or nuclear electromagnetic pulse (NEMP) when produced by a nuclear explosion.

What is a Notified Body?

ANSWER
A notified body is an organization nominated by a government of one of the Member States of Europe and recognized by the European Commission. A notified body is nominated based on specific requirements, such as knowledge, experience, independence and resources to carry out the compliance audits. 

The primary role of a Notified Body is to carry out conformity audit services under the conditions set out in the “New Approach” guidelines in support of CE Mark certification. This normally means that manufacturers are assessed for compliance with essential requirements in each directive. A conformity audit may consist of inspection, quality assurance, type examination or design examination, or a combination thereof. BSI is a notified body for many European directives.

What is Product Compliance?

ANSWER
Product compliance refers to the adherence of a product to regulatory standards, laws, and requirements set forth by governmental agencies or industry bodies. These regulations can cover various aspects of a product’s design, manufacturing, labeling, packaging, distribution, and disposal.

What is an Artificial Mains Network?

Used to supply the mains electrical voltage (either AC or DC) and current to the equipment under test (EUT). The AMN also establishes a measurement point for conducted emissions when stabilizing the impedance, inductance, and capacitance of the power supplied to the EUT
