Weights and Measures Regulations (C.R.C., c. 1605)

• 54. (1) Subject to subsection (2), the amount set out in Column II of an item in the appropriate Part of Schedule IV is hereby prescribed to be the tolerance for the purpose of subsection 13(1) of the Act for a local standard that has a nominal value set out in Column I of that item.

• (2) Where a local standard is tested to determine whether it is within the tolerance set out in a Part of Schedule IV for that local standard and the nominal value of that local standard is not specified in Column I of an item of that Part, the tolerance for that local standard shall be the amount resulting from linear interpolation between the tolerances set out in Column II of that Part opposite the specific nominal values set out in Column I of that Part that are nearest to the nominal value of the local standard being tested.

• (3) The tolerances set out in Parts XI and XII of Schedule IV for the nominal value of cylindrical graduated standards are also the tolerances for any other values that are marked on those standards as intermediate graduations.

• (4) For the purposes of subsection 13(1) of the Act, the tolerance for a local standard referred to in subsection 56(2) at any point within the measuring range designated by the owner of the standard for the purpose of use of the standard is two per cent of the value or reading of that point indicated by the reference standard.

55. [Repealed, SOR/90-118, s. 16]

• 56. (1) Every local standard described in column I of the table to this subsection shall be calibrated and certified at least once within the period set out in column II.
