Agricultural Product Standards Act, 1990 (Act No. 119 of 1990)RegulationsGrading, Packing and Marking of Rice Kernels intended for sale in the Republic of South AfricaPart IV : Determination of other substances and grain composition19. Determination of the kernel length/width |
The kernel length and width of rice in a consignment shall be determined as follows—
A. Kernel Length
The length of the sample of rice in a consignment shall be determined as follows—
| (a) | Using a divider separate two sets of 100 kernels from the sample without any broken part, by random selection. |
| (b) | Measure the length of the kernels using a micrometer Caliper and calculate the arithmetic mean of both sets of kernels. |
| (c) | Calculate the average length of the two sets of kernels: Provided that if the standard deviation is calculated as being higher than 2, return all the kernels to the tray and repeat procedure from paragraph (a). |
| (d) | Such an average length determined shall be deemed the average length of the rice in a consignment. |
B. Kernel Width
| (a) | Separate two sets of 100 kernels from the sample without any broken part, by random selection. |
| (b) | Measure the width of the kernels using a micrometer Caliper and calculate the arithmetic mean of both sets of kernels. |
| (c) | Calculate the average width of the two sets of kernels: Provided that if the standard deviation is calculated as being higher than 2, return all the kernels to the tray and repeat procedure from paragraph (a). |
| (d) | Such an average width determined shall be deemed the average width of the rice in a consignment. |
C. Kernel length/width Ratio
The average length and width previously calculated
