Regulations are current to 2023-01-11 and last amended on 2019-06-17. Previous Versions

PART VSpecifications Relating to Devices (continued)

DIVISION XIIMeasuring and Vehicle Tanks (continued)

Design, Composition and Construction (continued)

  •  (1) Subject to subsection (2), a common manifold connected to a vehicle tank may be split into two sections separated by means of a valve if the valve is designed so that it cannot be left in any open position.

  • (2) A gate valve may be used in place of the valve referred to in subsection (1) if the volume that can be diverted by leaving the gate valve open does not exceed 0.125 per cent of the capacity of the smallest tank connected to the manifold.

 [Revoked, SOR/93-234, s. 2]

 The piping on a vehicle tank restricted for use with bunker oil may be concealed by insulation or by parts of the tank to prevent the bunker oil from congealing.

 Individual compartments on a vehicle tank restricted for use with bunker oil may be connected to a common discharge manifold without any automatic means of preventing flow between the compartments.

Performance

[
  • SOR/2005-297, s. 42(F)
]

 A measuring tank shall be tested and calibrated with a liquid that has a thermal expansion coefficient, volatility and viscosity not greater than those of domestic furnace fuel oil and that will not have a corrosive effect on the tank.

  • SOR/2014-111, s. 40

 A measuring tank shall be tested and calibrated when all necessary supports have been installed and it is resting in the position in which it is designed to be used.

  • SOR/2014-111, s. 40

 A measuring tank, other than a vehicle tank, shall be calibrated to a valve immediately adjacent to the outlet connection on the tank.

  • SOR/2014-111, s. 40

 Unless otherwise authorized by specifications established by the Minister, a measuring tank that has a gauge glass or a slip type gauge shall not be calibrated for a delivery of less than 50 per cent of the measuring tank capacity.

  • SOR/2014-111, s. 45
  •  (1) Subject to subsection (5), when a measuring 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 measuring tank is within the acceptance limits of error in respect of that known test volume if the actual volume of the measuring 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 measuring 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 measuring tank is within the in-service limits of error in respect of that known test volume if the actual volume of the measuring 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.

  • (5) The limits of error for a measuring 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 measuring tank, including errors due to entrapment of air or liquid by parts of the measuring tank or its associated piping, equipment or accessories during filling or emptying.

  • SOR/89-570, s. 6(F)
  • SOR/94-691, s. 4(E)
  • SOR/2014-111, ss. 41, 45

 A vehicle tank shall be tested to ensure that air or liquid is not trapped therein in excess of 0.125 per cent of the capacity of the tank under conditions of normal use.

  • SOR/2014-111, s. 47(F)

Installation and Use

 A fixed measuring tank shall be installed on substantial supports adequate to ensure that the position of the measuring tank remains constant and level with reference to the levelling ledges.

  • SOR/2014-111, s. 45

 A fixed measuring tank shall be level when filled, as shown by the levels installed on the tank or by the levelling ledges, and, when in use, a portable measuring tank or vehicle tank shall be filled and emptied when it is as close to level conditions as possible.

  • SOR/2014-111, s. 42

 When a measuring tank is being filled, care shall be taken to minimize the possibility of air being trapped in the piping or entrained in the liquid.

  • SOR/2014-111, s. 45

 A measuring tank shall not be used for deliveries of quantities between internal capacity indicators.

  • SOR/2014-111, s. 45

 A vehicle tank not equipped with level gauges shall, when being used to measure, be on a surface that is within three degrees of level.

 A vehicle tank that is equipped with level gauges shall, when being used to measure, be level within the limits marked on the level gauges.

 A vehicle tank shall be supported in a manner that will not distort the tank when the vehicle is driven under conditions of normal use.

 If emergency valves are installed on a vehicle tank calibrated with wet lines, they shall be open when the tank is being filled.
