3. Metrology Basics Mistakes can make measurements and counts incorrect
Even if there are no mistakes, nearly all measurements are still inexact
why ?
4. What is Metrology ? Metrology is the science that establishes the correctness of specific measurement situations. This is done by anticipating and allowing for both mistakes and error. .
6. What is Calibration? Calibration is the process where metrology is applied to measurement equipment and processes to determine confromity with a known standard of measurement usually tracable to a national standards board
7. Some common standards include:
ISO 17025:2005—General Requirements for Calibration Laboratories
ISO 9000—Quality Systems Management
ISO 14000—Environmental Management
21 CFR Part 210/211—FDA Regulations concerning GMP (Good Manufacturing Practices) Quality Systems

16. Measurement System Analysis (MSA )
17.
A Measurement Systems Analysis considers the following:
Selecting the correct measurement and approach
Assessing the measuring device
Assessing procedures & operators
Assessing any measurement interactions
Calculating the measurement uncertainty of individual measurement devices and/or measurement system
18. measurement uncertainty describes a region about an observed value of a physical quantity, also called a measurand, which is likely to enclose the true value of that quantity.
Measurement uncertainty may be denoted by error bars on a graph, or by the following notations:
measured value ± uncertainty
measured value(uncertainty) Measurement Uncertainty
