Measurement Uncertainty

In order to be confident in test results it is vital to know the uncertainty and how much confidence you can place on that uncertainty. 

To take an example:- if you measure the length of the piece of string  to what measurement tolerance or uncertainty will you quote the result? Say you quote it to ± 0.5 mm. How often will further measurement results come within ± 0.5 mm of your result. Will it be  95% or 99% of the time. How do you estimate this?

If you don't know your measurement uncertainty in your process and final test measurements how confident can you be that you are in compliance with any critical specifications for your product or service?

Traceability of measurement device calibration takes you back to the commonly agreed international standard and if both your and your supplier's measurement devices are traceably calibrated back to a common standard a potential source of error is removed.

What other factors might affect careful measurements and how do you add any contribution these might make to the measurement uncertainty?

KMS are expert in Measurement Uncertainty . We have enabled  a major multinational group site to get accredited to ISO 17025 for which they were subsequently awarded their Group Centre of Excellence for Calibration status (ahead of many other international sites). We've also provided Measurement Uncertainty  services in DNA Paternity Testing and Marine Renewables environments.

• Establish estimation of the measurement uncertainty.
• Provide  management supports for reporting of measurement uncertainty
