Correct Answer - Option 1 : Legal Metrology
Explanation:
Legal metrology:
Legal metrology is basic to guarantee correctness and equity in commercial transactions and to protect the health and well-being of the members of society, as well as the environment. Everyone benefits from the availability and implementation of a legal metrology system: individuals, both as consumers and as entrepreneurs, and Government. The actions of legal metrology require the guarantee of access to proper measurement standards for the base units, verification that instruments and measuring procedures of daily commerce are correct, and checking of measurement results whenever the public interest is involved. These actions can be carried out directly by a legal metrology entity or be partially delegated in the framework of a national system of metrology and accreditation.
Broadly, we can say that legal metrology is that branch of Metrology whose purpose is to verify the observance of technical and legal standards related to measurement units, methods and procedures of measurement, measuring instruments, and materialised units. Its aim is to guarantee correctness and equity in commercial relations and to protect the health and wellbeing of the members of society, as well as the environment
Industrial Metrology:
"The science of measurement” can be applied across multiple different industries to serve different purposes. Commonly used for scientific or fundamental metrology, industrial metrology, and legal metrology, the concept of metrology has developed from merely theory to practicality.
Industrial metrology is the use of “the science of measurement” in theory and practicality, to the manufacturing process, ensuring quality and accuracy of manufactured parts and components. The method of testing these parts to ensure accuracy and reliability must be calibrated according to national and/or industry standards.
Scientific Metrology:
Scientific Metrology, also known as Fundamental Metrology, covers the establishment of units of measure, unit systems and quantity systems. It is scientific metrology that sets the standards that are adopted as the definite magnitude of a physical quantity.
