mm and a length/width ratio between 2.0 and 3.0 after milling to a well- milled degree; 
and 
 
c) Short grain rice - Rice with 80% or more of kernels having a length of less than 6.20 
mm and a length/width ratio of less than 2.0 after milling to a well -milled  degree.  
 
4 Application of this  standard  
4.1 All determinations shall be made on the basis of the original sample.  
 
4.2 Percentages shall be determined on the basis of weight.  
 
4.3 Kernels with defects, once assigned to a particular categor y, shall not be used in another 
category.  
 
4.4 For broken rice assessments, the total broken rice shall be  extracted.  
 
4.4.1  To estimate the broken rice in mixed varieties, the kernel fragments shall be determined 
and its length shall be less than three- quarters of the average length of the corresponding whole 
kernels.  
 
4.4.2  Discolouration (yellow, amber and other heat damaged kernels) shall be estimated in 
the milled  sample.  
 
4.5 When a kernel has several defects, it shall be classified according to the category in which 
the maximum permissible value is the  lowest.  
 
4.6 All parts of kernels which remain in the perforations of a sieve shall be considered to be 
retained by the  sieve.  
 
4.7 Average length shall be determined on the basis of measuring the length of one hundred  
(100) whole kernels chosen at random.  
 
4.8 Mechanical sizing of kernels shall be adjusted by methods given by the regulatory 
authority of the particular Member  State.  
 
4.9 Moisture content in paddy or milled rice shall be determined by a recommended device as 
outlined in Annex A and in accordance with the procedures described in Annex B and or by ISO 
712:2009.  DJS 368:2023

c) Record  findings.  
 
B.2 Procedure - Moisture  content  
a) Using a divider reduce a sample of 500 g to two samples  (replica).

B.3 Procedure for classification length/width  ratio  
B.3.1  Determination of kernel  length  
 
a) Using a divider, reduce a sample of 200 g to two samples of 35 g  each.  
 
b) From one 35 gram, select 100 whole kernels at random. Each kernel measured individually 
with a digital  calliper , with accuracy of 0.01 mm. The average length is calculated. The 
procedure is repeated using the second 35 g  sample.  
 
c) The average length of the kernels for both samples is  calculated.  
 
d) Measured kernels are returned to the  samples.  
 
B.3.2  Determination of  kernel  width  
 
a) Using a divider, reduce a sample of 200 g to two samples of 35 g  each.  
 
b) From one 35 g sample select 100 whole grains at random. The width of each kernel is 
measured individually with a digital calliper , with accuracy to 0.01 mm. The average width 
is calculated.  
 
c) The procedure is repeated using the second 35 g  sample.  DJS 368:2023  
17  
  
 
d) The average width of kernels for both samples is  calculated.  
 
e) Measured kernels are returned to the  sample.  
 
B.3.3  Determination of kernel length/width  ratio  
 
B.3.3.1  The kernel length/ width ratio is calculated by  using:  
 
a) The average length calculated  previously.  
 
b) The average width calculated  previously.  
 
c) The following formula below is used to calculate the length/width  ratio:  
 
Length/width ratio = average length of grain  
average width of grain  
B.3.3.2  The length/width ratios of kernels are as  follows:  
 
a) Extra long: >  3.5 
 
b)    Long: 3.0 – 3.4 
 
c) Medium: 2.0 -  2.9 
 
d) Short: <  2.0 
 
B.4 Procedure - Analysis of total broken  kernels  
a) Weigh two approximately 35 g samples to ascertain correct  weight.  
 
b) Remove all broken  kernels.  
c) Weigh the broken kernels, and calculate the percentage as  follows: 
broken in sample (%) = w eight  of broken  X  100  
weight of sample

NOTE  Only whole kernels are used in the analysis of the above factors . 
 
b) Factors are separated and weighed and the percentage of each factor determined  as follows : 
 
Factor in sample (%) = weight  of factor  X 100 
weight of sample  
 
c) Calculate the average of the two samples and record  result.  
 
NOTE  The average is used as the representative perc entage. 
 
B.6 Procedure to determine head rice  yield  
a) Make a test run in the milling machine with cargo rice to determine the time taken to 
achieve a well milled degree. This time will vary with different varieties and  types.  
 
b) Having determined the milling time, weigh approximately 200 g of cargo rice and mill for 
the length of time  determined. 
 
c) Weigh the total milled rice (A) and record the weight obtained. Using a sample divider, 
reduce the milled rice to two working samples of 50 g  each.  
 
d) Remove all broken ker nels from the first 50 g sample. Weigh and record the value of the 
head rice (B) obtained from this  sample.  
 
e) The head  rice yield  of the first  50g sample  is calculated  using  the formula  below: - 
 
Head rice, B, (%) = Head rice X 100 
Sample  weight  
Head rice  yield,  (%)  B X A X 100  
100   
200  
EXAMPLE  A worked example is shown  below:  
 
Head rice= 42g  
Total milled rice = 131g 
Sample weight = 50g  DJS 368:2023  
19  
  
B% = 42   = 0.84  
50 
Head rice yield (%) = 0.84 X 131 X 100  =55.02%  
200  
 
f) Head rice yield determination is repeated on the second 50 g sample and the average value 
recorded. If the difference between the results of the two determinations, carried out 
simultaneously, exceeds 1.0 % absolute, the test shall be repeated.  
 
 
B.7 Procedure for determinati on of  colour  
Using a representative sample:  
 
a) Pass sample through boerner divider and reduce to three  sub-samples.  
 
b) Weigh accurately the same amount for each  sub-sample.  
 
c) Standardise meter by inserting sample case with calibration plate and by pressing sens itivity button reading does not correspond to  86.2.  
 
d) Place sample holder with first sub -sample into the  machine.  
 
e) Record meter  reading.  
 
f) Discard  sample.  
 
g) Repeat steps c to e using the other two  samples.  
 
Meter sensitivity reading can vary by ± 0.4.

END OF DOCUMENT   
 Standards Council  
The Standards Council is the controlling body of the Bureau of Standards and is responsible for the policy and general 
administration of the Bureau.  
The Council is appointed by the Minister in the manner provided for in  the Standards Acts . The Council appoints 
committees for specific purposes.  
 
The Standards Act, 1968 sets out the duties of the Council and the steps to be followed for the formulation of a standard. 
Preparation of standards document  
 
The following is an outline of the procedure which must be followed in the preparation of documents:  
 
1. The preparation of standards documents is undertaken upon the Standards Council’s authorization. This may  
arise out of representations from national organizations or existing  Bureau of Standards’ Committees or Bureau 
staff. If the project is approved it is referred to the appropriate sectional committee or i f none exists a new 
committee is formed, or the project is allotted to Bureau  staff.  
 
2. If necessary, when the final draft of a standard is ready, the Council authorizes an approach to the Minister in  
order to obtain the formal concurrence of any other Minister who may be responsible for any area which the standard  affects.  
 
3. With the approval of the Standard Council, the draft document is made available for general public comments. 
All interested parties, by means of notice in the Press, are invited to  comment.  In  addition  copies  are forwarded to those know n to be interested in the  subject.  
 
4. The Committee  considers  all the comments  received  and recommends  a final document  to the Standards  Council.  
 
5. The Standards Council recommends the document to the Minister for  publication.  
 
6. The Minister approves the recommendation of the Standards  Council.  
 
7. The declaration of the standard is gazetted  and copies placed for  sale. 
 
8. On the recommendation of the Standards Council the Minister may declare a standard to be  compulsory.  
 
9. Amendments to and revisions of  standards normally require the  same procedure as is applied to the preparation  
of the original  standard.  
 
 
Overseas standards documents  
The Bureau of Standards maintains a reference library which includes the standard of many overseas organizations. These 
standards can be inspected upon request.  
 
The Bureau can supply on demand copies of standards produced by some national standards bodies and is the agency for 
the state of standards produced by International Organization for Standardization (ISO) members.  
Application to use the reference library and to purchase Jamaican and other standards documents should be addressed to:
