METROLOGY

• Metrology is the science of measurement and it is
  an essential to nearly all aspects of our everday
  activities
• production control
• measurement of environmental quality
• assessment of health and safety
• assurance of fair trade
• research and development
• consumer protection, etc.

Metrology is commonly considered in three
categories/groups

• Scientific Metrology Deals with problems
  common to all metrological questions
  irrespective of the quantity measured - it
  touches on the general theoretical and practical
  problems related to units of measurement.
• Industrial Metrology focuses on measurements
  in production and quality control, typical issues
  are calibration procedures/intervals, control of
  measurement processes, and management of
  measuring equipment
• Legal Metrology relates to mandatory technical
  requirements - areas of public interest such as
  trade, health , environment and safety . The
  scope of Legal Metrology depends on national
  regulations and may differ from country to country

Metrological Units
1964 Known as MKSA system (metre, kilogram,
second, ampere) 1960 The MKSA
System then assumed the name of the
International System of Units,
abbreviated SI(given the name by the 11th
General Conference of Weights and
Measures) The SI units in
metrology are based on seven base units (m, kg,
s, A, K, mol and cd). Others such as
volume,speed,density,force are known as SI
derived units

Calibration
Set of operations that establish under specified
conditions, the relationship between values of
quantities indicated by a measuring instrument or
measuring system, or values represented by a
material measure or a reference material, and the
corresponding values realized by standards

Traceability
Property of the result of a measurement or the
value of a standard whereby it can be related to
stated references, usually national or
international standards, through an unbroken
chain of comparisons all having stated
uncertainties.

Measurement Uncertainty
Associated with the result of a measurement that
characterises the disperasion of values that
could reasonably attributed to the measurand. The
estimation of uncertainty in accordance with GUM
guidelines is usually accepted.

Source of Measurement Uncertainty

• Instrument resolution
• Environmental factors
• Random variation in repeated
• observation
• Uncertainties in values of
• measurement standards and reference
• materials
• Personal bias / human error, etc.

CONCLUSION
Metrology, the science of measurement, is an
essential part of standards, technical
regulations and conformity assessment procedures.
Therefore each government has to take
responsibility for ensuring the establishment and
proper functioning for a credible measurement
system, including setting regulations for the
legal applications of metrology, developing
standards for measurement and calibration,
preparing regulations for measuring instruments
used by producers ,testing laboratory general
public.
