Weights and Measures Regulations

Version of section 325 from 2006-03-22 to 2014-07-31:

  •  (1) Subject to subsection (5), when a tank is tested for acceptance limits of error using a known test volume determined in relation to a relevant local standard and set out in Column I of an item of a table to subsection (3) or (4), the tank is within the acceptance limits of error in respect of that known test volume if the actual volume of the tank

    • (a) does not exceed the test volume by an amount in excess of the amount set out in Column II of that item; and

    • (b) is not less than the test volume by an amount in excess of the amount set out in Column II of that item.

  • (2) Subject to subsection (5), when a tank is tested for in-service limits of error using a known test volume determined in relation to a relevant local standard and set out in Column I of an item of a table to subsection (3) or (4), the tank is within the in-service limits of error in respect of that known test volume if the actual volume of the tank

    • (a) does not exceed the test volume by an amount in excess of the amount set out in Column III of that item; and

    • (b) is not less than the test volume by an amount in excess of the amount set out in Column III of that item.

  • (3) Subject to subsection (5), the limits of error set out in the following table apply to all measuring tanks whether fixed, portable or vehicle mounted, that are calibrated in terms of metric units of volume:

  • (5) The limits of error for a tank that is designed for use in measuring liquefied gases are twice the applicable limits of error set out in the table to subsection (3) or (4).

  • (6) The limits of error set out in the tables to subsections (3) and (4) refer to the total inaccuracy of measurement by the tank, including errors due to entrapment of air or liquid by parts of the tank or its associated piping, equipment or accessories during filling or emptying.
