Legal Metrology Act, 2014 (Act No. 9 of 2014)RegulationsLegal Metrology Regulations, 2017Part XI : Measuring instruments and containers used for prescribed purposes70. Construction and strength of weighing instruments and measuring instruments |
| (1) | Any measuring instrument must be— |
| (a) | so designed and constructed of such material as will effectively preclude inaccurate measurement owing to any property of the product being measured; and |
| (b) | sufficiently strong to withstand, without distortion, a load equal to the capacity of the measuring instrument or the maximum pressure at which it is designed to work for the duration of the verification periods as specified. |
| (2) | A measuring instrument must be such that correct measurement is not affected by— |
| (a) | fluctuation in supply voltage and frequency; |
| (b) | externally or internally generated electromagnetic or electrostatic interference; |
| (c) | atmospheric conditions such as humidity or pollution; |
| (d) | vibration from any source; |
| (e) | other environmental conditions; or |
| (f) | constructional conditions e.g. civils. |
| (3) | Where technical regulations for specific types of measuring instrument identify and set requirements for specific influence factors and disturbances, the requirements in subregulation (2)(a) to (f) are deemed to have been complied with if the measuring instrument complies with the specified requirements pertaining to it. |
