COVERAGE:
Considering the growth of the Belizean markets, the coverage/scope of legal metrology would naturally be extended to address, resources permitting, weighing and measures devices/instruments beyond those at your local convenient store. Today, the Belize Bureau of Standards verifies devices and instruments used in production as well as those used in the service industry. Routine verification exercises are carried out at the Sugar, Citrus, Flour, Rice facilities/plants and Feed Mills. In the service industry, exercises are carried out at local and international airlines, private medical facilities, post offices etc., fuel stations, LPG depots.
Instruments/Devices that pass the verification exercise are affixed with a sticker of accuracy. This is a tamper proof BBS sticker that carries a unique serial number and the period for which the sticker is valid.

Scales used to sell product as per by-laws are subject to initial and subsequent verification. These equipment are verified twice per year and the equipment owner is charged a small fee for this service.

The verification of meters are not subject to regulations at this time.

This exercise if conducted simultaneously with the verification of commercial scales. Therefore, the frequency of scheduled coverage indicated above applies.
