Installation and Use

 A machine shall be firmly attached to a counter or other stable support before it is used.

 Registration shall be returned to zero before each use of the machine.

DIVISION VIIIArea Measuring Machines

Interpretation

 In this Division, machine means an area measuring machine for use in trade.

Design, Composition and Construction

 A machine shall be designed so that any means of adjustment that can have an effect on its accuracy of measurement has provision for sealing.

Performance

[SOR/2005-297, s. 42(F)]

 When a machine is tested in relation to a relevant local standard for either acceptance limits of error or in-service limits of error by measurement of a known area on a surface that is representative of the kind of material for which the machine is designed, the machine is within both the acceptance limit of error and the in-service limit of error in respect of that area and that kind of material if the area registered does not differ from the known area by more than 0.006 square metres or 1.5 per cent of the known area, whichever is greater, and, in the case of a machine measuring in Canadian units of measurement, 1/16 square foot or 1.5 per cent of the known area, whichever is greater.

  • SOR/89-570, s. 6(F)
  • SOR/2017-17, s. 15

DIVISION IXSolid Volume Measuring Machines

Interpretation

 In this Division, machine means a machine for determining the computed volume of boxes and other solids on the basis of three mutually perpendicular linear measurements.

Design, Composition and Construction

 Measuring faces on a machine shall be designed so that they may be held parallel when each of the three principal axes of the object are being measured.

 A machine shall provide registration of measurement in terms of either cubic decimetres or cubic feet.

Performance

[SOR/2005-297, s. 42(F)]

 When a machine is tested in relation to a relevant local standard for acceptance limits of error by taking the measurement in turn of three lengths the product of which corresponds to a computed volume set out in Column I of an item in a table to section 230 or 231, the machine is within the acceptance limits of error in respect of that computed volume if the amount registered by the machine

  • (a) is not less than the computed volume by an amount in excess of the volume set out in Column II of that item; and

  • (b) does not exceed the computed volume by an amount in excess of the amount set out in Column III of that item.

  • SOR/89-570, s. 6(F)

 When a machine is tested in relation to a relevant local standard for in-service limits of error by taking the measurement in turn of three lengths the product of which corresponds to a computed volume set out in Column I of an item in a table to section 230 or 231, the machine is within the in-service limits of error in respect of that computed volume if the amount registered by the machine

  • (a) is not less than the computed volume by an amount in excess of the volume set out in Column IV of that item; and

  • (b) does not exceed the computed volume by an amount in excess of the amount set out in Column V of that item.

  • SOR/89-570, s. 6(F)

 The limits of error set out in the following table apply to all solid volume machines designed to establish the space in cubic decimetres taken up by packages, parcels and crates:
