| (1) | Unless otherwise approved by the National Regulator or as described in the provisos following Table 2, any indication of the result of a measurement by any graduated measuring instrument, other than a material measure, which is to be approved in terms of section 22 of the Act, or any indication of the result of a measurement by any new graduated measuring instrument, other than a material measure, which does not require to be approved in terms of section 22 of the Act, must be indicated in terms of only one unit of the measurement units referred to in regulation 2 of this Part and any figured subdivisions of such units must be indicated as decimal submultiples thereof. |
| (2) | Unless otherwise approved by the National Regulator, the applicable measurement unit referred to in subregulation (1) must be that shown in Column 4, Table 2 in respect of the category of measuring instrument, other than a material measure. |

Provided that—
| (a) | in respect of a weighing instrument having a capacity of more than 1 000 kg, the unit may be the metric tonne (t); |
| (b) | in respect of a volume measuring instrument for liquids having a capacity of more than 1 000 L the unit may be the kilolitre (kL) or the cubic metre (m3); |
| (c) | where the capacity according to Column 3— |
| (i) | in the case of a weighing instrument is 1 kg or 1 g, the unit for the terminal indication may be 1 kg or 1 g, respectively; |
| (ii) | in the case of a length measuring instrument is 1 m, the unit for the terminal indication may be 1 m; |
| (iii) | in the case of a volume measuring instrument is 1 L, the unit for the terminal indication may be 1 L; |
| (d) | any capacity referred to in the Table 2 is the total value indicated directly or indirectly on the indicating dial or graduated scale of the measuring instrument including the value of any means of increasing the measuring range including, in the case of a weighing instrument, any loose proportional counter poise, but excluding the value compensated by any loose weight in the case of a semi-selfindicating weighing instrument or by any separate adding tare compensating device. |
