4. Metrology Metrology, the science of measurements
Metrology is often divided into three subfields:
Scientific or fundamental metrology
Applied or industrial metrology
Legal metrology

5. Metrology Subfields... Scientific or fundamental metrology
The establishment of measurement units, 
Unit systems, 
The development of new measurement methods.
Realization of  measurement units. 
The transfer of metrological traceability from these 
standards  to users in society.

6. Metrology Subfields... Applied or industrial metrology
The application of measurement science to 
manufacturing and other processes 
Their use in society, ensuring the suitability of 
measurement instruments, 
The calibration and quality control of measurement

7. Role of Legal Metrology
Regulatory requirements of measurements and 
measuring  instruments for the protection of health, 
Public safety, 
The environment, enabling  taxation, 
Protection of consumers and fair trade.

8. Role of Legal Metrology…
Legal metrology relies on the following activities:
1. establishing the law & 2. supervising the law;
3. Providing traceability for measurements and measuring instruments.
Legal metrology compliments scientific and industrial measurement.
Supports the practical application of measurements

9. Role of Legal Metrology…

10. Purpose of calibration
There are three main reasons for having equipment's calibrated:
To ensure readings from an equipment's are consistent with other measurements.
To determine the accuracy of the equipment readings.
To establish the reliability of the equipment i.e. that it can be trusted.
Calibration cover the follows:
Traceability: relating your measurements to others.
Uncertainty: How accurate are your measurements?
Reliability: Can I trust the equipment's?
Achieving Traceability in your measurements.

11. Traceability Pyramid Chart
National Measurement Standard (e.g., NIST)
NMISA
NMI
SANAS
Accredited Laboratories
End user such Hospitals, Nuclear Industries and Mining.

12. Application of Metrology
Mining & Nuclear Industries
Safety and radiation protection
Control of radioactive materials
Control of workers’ radiation doses
Measurement of radiation
Conventional health and safety
Protecting the public
Measure key parameters in the environment
Estimate potential dose to the public
Protecting the environment
Control releases to the air, to surface water and to ground water
Measure releases: effects • Take action, when require

13. Application of Metrology

14. Application of Metrology The role of Metrology in the Hospitals
Medical devices or Equipment's
Any instrument, apparatus, appliance, or in combination, for its intended to be used for human beings for the purpose of:
diagnosis, prevention, monitoring, treatment of disease, injury or handicap, investigation, replacement of the anatomy or of a physiological process, control of conception
Most of the medical devices are :
Calibrated
Test and verifications
High decision are taken based on unreliable devices or equipment's.
Estimated 44,000 – 98,000 medical error deaths

15. Application of Metrology The role of Metrology in the Hospitals
Medical devices

16. Science of Measurement was Compromised???

17. Conclusion
Science of measurements plays a key role in the manufacturing, nuclear industries, mining and hospitals.
Good decision are achieved base on measurements results.
Closing the gap between the laboratory language and the end user that is interpretation of calibration certificates.
Educate the end user how to correlate the calibration certificates in the work fields environment.
