Legal metrology is the branch of metrology that deals with laws and regulations relating to units of measurement, measuring devices and measurement methods.  It helps provide support and protection to areas such as public safety, health, the environment and trade.

Indeed, one of the main roles of legal metrology is to ensure that measuring devices used in trade provide accurate measurements.  This is done through a process called verification.  This involves conducting a series of tests on the measuring device, such as a scale or fuel dispenser, to ensure that it is measuring accurately and reliably.

From a trade or commerce perspective, consumers and traders make decisions based on measurement results daily; measurements that affect economic and personal well-being.  Thus, a well-functioning society must have confidence in its measurements.

Governments therefore need to give society the means to establish confidence in measurement results, so that traders, consumers, regulators, industry and others can make informed decisions based on accurate measurements.  This is a role supported and facilitated by a sound legal metrology system.  In fact, public trust in good measurement enforcement encourages respect for and compliance with the law.

A robust and working legal metrology system is a fundamental need for any country. Having been proclaimed in 2015, the country’s metrology legislation – the Metrology Act No.18 of 2004 – formalizes, the legal metrology system and gives citizens greater assurance in the measurement capabilities of the country.
