What is legal metrology?
|Legal metrology is the application of legal requirements to measurements and measuring instruments|
Measurements are so much a part of our daily lives that we often take them for granted and possibly don’t even notice them. For example
Very often, small errors in either direction average out over a large number of measurements. But biased errors can create considerable financial prejudice - for example, inaccurate measurements of oil at each of the many transaction points from the oil well to the end consumer can have serious economic consequences.
As another example of the importance of measurement, incorrect radiation doses in cancer treatment can have a critical effect on our health.
Legislation on measurements and measuring instruments is required in all these cases, as well as when there is a need to protect both the buyer and the seller in a commercial transaction, or where measurements are used to apply a sanction. Virtually all countries provide such protection by including metrology in their legislation – hence the term “legal metrology”.
Creating global standards for use in legal metrology legislation is the role of the OIML [Read more].
