The following are the role of legal metrology which deal with the weights and measurements in packaged commodities.

Checking Of the Net Quantity of Commodities in Packages

  • The Controller or any Legal Metrology Officer authorized under the Act to determine and check the net quantity of a packaged commodity shall be provided by the concerned Government with adequate equipment to carry out his work to determine the degree of accuracy practically and efficiently.
  • Before determining the net quantity in any package, the Controller or Legal Metrology Officer shall ensure that the operational standards and other equipment function correctly.
  • Every manufacturer, importer, packer or wholesale dealer must render such assistance to the Controller or any Legal Metrology officer to carry out his duties efficiently.
  • Any weights and measurements owned by the manufacturer, importer, packer or wholesale dealer are used by any Legal Metrology officer to verify the net quantity contained in any package. The authorized person will release such weight and measure once his work is completed.

Instructions about the Determination of Quantity and Error at the Manufacturer’s or Packer’s Premises

  • The empty tare shall be taken and determined to determine the weight of package commodities. Suppose the tare package of the concerned product weight is equal to or less than 3/10 of the maximum permissible weight for the concerned commodity. In that case, it can be used to determine the net quantity of individual packages.
  • To check the Net weight, in the absence of any empty tare packages, one sample package shall be opened, and the net weight, the tare weight of the package shall be determined to check whether the importer or manufacturer followed the standards of the legal metrology act.
  • To cross-check the length of the commodity, the package can be opened if it is impossible to measure the package without opening and shall be measured through a calibrated steel tape of suitable length.
  • The authorized Authority reads the actual net volume of the commodity in every package and shall be noted carefully for verification.

The role of legal metrology is to obtain the controller or any Legal Metrology officer to document the results of these examinations of gross weight, net weight and tare weight of the commodity in the Form specified in the Eleventh Schedule of the Act along with any other observation as he may wish to make a note. These observations were then verified for granting the LMPC certificate or renewal or during the inspection to determine the standards of weights and measures followed by the manufacturers or importers.
