181. When a machine that is of the self-indicating or semi-self-indicating type is tested by

  • (a) the removal of a known test load, in the case of a machine that is normally used for weighing following the addition of load, or

  • (b) the addition of a known test load, in the case of a machine that is normally used for weighing following the subtraction of load,

the acceptance and in-service limits of error are 1.5 times the limits of error set out in the tables to sections 176 and 177 and set out in sections 188 and 192.

  • SOR/89-570, s. 6(F).

  • 182. (1) Subject to subsections (2) and (3) and sections 188 and 192, the minimum limit of error when a machine is tested for acceptance or in-service limits of error is a weight equivalent to 0.05 per cent at the capacity of the machine or one minimum increment of registration, whichever is the lesser.

  • (2) The minimum limit of error for a railway track scale used exclusively in weighing railway cars is the greater of 15 kg or 30 pounds, and the value of the minimum increment of registration.

  • (3) In a strain test at a heavy duty scale, there shall be no minimum limit of error in respect of the known test load that is added to the strain load and the limit of error for a machine with digital registration shall not be increased as described in section 184.

  • SOR/89-570, s. 6(F);
  • SOR/90-118, s. 23;
  • SOR/93-234, s. 2(F).

183. On removal of all load from a machine, the means of registration of the machine shall immediately return to zero registration within a range equivalent to the greater of

  • (a) ¼ of the value of the minimum increment of registration, and

  • (b) 0.01 per cent of the capacity of the machine.

  • SOR/90-118, s. 24.

184. Subject to subsection 182(3), where a machine has digital increments of registration, the acceptance and in-service limits of error applicable to the digital registrations of the machine shall be increased beyond the limits of error otherwise applicable to the digital registrations of the machine by the equivalent of one-half the finest digital increment of registration.

  • SOR/89-570, s. 6(F).

  • 185. (1) Where a test consisting of the application to a machine of the same test load up to 10 times is carried out under conditions approximating conditions of normal use, the difference between the least registered load and the greatest registered load shall not exceed the absolute value set out in column II or III, as applicable, of an item of the appropriate table to sections 176 and 177 that corresponds to the known test load set out in column I of that item that is equivalent to the greatest registered load.

  • (2) Subsection (1) does not apply to the testing of a machine in accordance with subsection 189.2(1), 190(2) or 191(1) or (2).

  • SOR/89-570, s. 6(F);
  • SOR/90-278, s. 5;
  • SOR/93-234, s. 2(E).
