Agricultural Product Standards Act, 1990 (Act No. 119 of 1990)RegulationsRegulations relating to the Grading, Packing and Marking of Pulses intended for sale in the Republic of South AfricaPart III : Sampling15. Sampling by means of a bag probe |
| (1) | he sampling of a consignment with a bag probe shall be done as follows: |
| (a) | Insert the tapered end of the bag probe upwards at an angle of approximately 30 degrees with the horizontal line and with the aperture thereof downwards, into each bag chosen from that consignment, until the end of the probe is approximately in the centre of such bag. |
| (b) | Turn the bag probe through approximately 180 degrees on the longitudinal axis thereof so that the aperture thereof is at the top. |
| (c) | Extract the bag probe with a slight shaking movement and diminishing speed from the bag concerned to ensure that a relatively even and increasing flow of pulses is maintained through the aperture thereof closer to the side of the bag. |
| (d) | Place the material contained in the bag probe in a suitable container. |
| (e) | Repeat the procedure described in subparagraphs (a), (b) and (c) alternately at various depths of alternate bags and place the material thus removed in the container referred to in subparagraph (d). |
| (f) | Take approximately equal quantities of material from each bag that is sampled. |
| (g) | Thoroughly mixes the material thus obtained and divide it by means of a sample divider to obtain a sample of at least 1 kg. |
| (2) | A bag probe referred to in subregulation (1) shall— |
| (a) | be long enough so that the end thereof will reach the center of a bag being sampled; |
| (b) | consist of a cylindrical tube with a tapered end and an aperture close to the end; and |
| (c) | have a diameter not exceeding 22mm. |
