Consistency in Measurements
Time
Location
Person or Company
Why do we need consistency in
measurement?
Trade and International Trade
Removal of Technical Barrier
Mutual Recognition of Measurement Result
CONCEPT
 Traceability
• Property of a measurement result or values of a
standard :
1. the result can be related to a reference
2. through a documented unbroken chain of
comparisons
3. each contributes to the measurement uncertainty
Traceability
An unbroken
chain of
comparisons
