Legal Metrology is the practice and process of applying regulatory structure and enforcement to metrology. This part of metrology ensures the transparency of economic transactions, environment and health safety by guaranteeing accuracy of measurement in relation with technical mandatory and legal requirement.

In our daily life, we need measurements. When measurement is not well controlled, it affects the economic and health life as different sectors make decision based on measurement results.

Legal metrology aims to:

  • Control the usage of measuring equipment in trade, law enforcement, health services and environmental protection through type approval, initial and periodic verifications and inspections;

  • Control pre-packaging operations;

  • Manage regional and international relationships in the area of legal metrology.

  • develop regulation and mistrial orders

  • protect consumers, environment and traders

e.g: Verifying the meter of fuel dispensers at petrol stations to ensure they are delivering the correct amount of fuel to consumers corresponding to the amount paid
