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.
Sailors have their own unique vocabulary. For instance, they say “heads” instead of toilets, “fore and aft” for front and back, “port” and “starboard” for left and right, and “halyards” or “sheets” instead of lines or ropes. There are many more examples, which can be confusing for non-mariners.
Similarly, experienced EMC engineers use specialized terms like LISNs, CDNs, FARs, OATS, BCI, and ESD, which can be perplexing for electrical and electronic engineers.
This page is designed to clarify these terms and make the concepts easier to understand.

A harmonised standard is a European standard developed by a recognised European Standards Organisation: CEN, CENELEC, or ETSI. It is created following a request from the European Commission to one of these organisations.
Manufacturers, other economic operators, or conformity assessment bodies can use harmonised standards to demonstrate that products, services, or processes comply with relevant EU legislation.
What is a Medical Device
ANSWER
The term “Medical Devices” encompasses a wide array of products used in healthcare for diagnosis, prevention, monitoring, treatment, or alleviation of diseases and injuries. Under the European Medical Devices Regulation (MDR), which is Regulation (EU) 2017/745, a medical device is defined with specific criteria and encompasses several categories based on their intended use and risk classification…….LINK TO FULL ANSWER

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.
