Abstract:

Have you ever asked the question "what is an En Number?" If you have you are not alone. I had the opportunity to ask several senior metrologists recently and the only answer I received was "I'll get back to you on that one". En Number (denoted as En in ISO Guide 43-1) is a widely used method in analyzing performance levels in inter-laboratory comparisons. Well, I had discussions with metrology statisticians and did additional researched on En and finally came to a basic understanding on its use and application. Understanding the meaning and use of En can be a very useful tool to the working metrologist. The intent of this paper is to describe the basic understanding and application of En to your inter-laboratory measurement data.
