1.3
The selection of bags for sampling shall be done at random and
shall cover bags from various position in the entire pile.
The following formula shall apply on the conduct of random sampling:
r
=
N
/ n
where:
r
= random number
N
= total number of bags in lot
n
= numbers of bags to be drawn
To identify the bag to
sample
corresponding to a given random number, count
consecutively starting from any container bag as reference in the order of 1,2, 3 up to 4 and so on. Every
rth
container shall be
sample
d.
If
r
is not a whole number, its value shall be rounded-off to the nearest whole number.
1.4 Procedure for Drawing

s collected in a sample bag shall be spread separately on a clear piece of paper, cloth or any suitable receptacle and subjected to visual examination.
d)
If results of visual examination indicate that
sample
s drawn
from different positions of the pile were found homogeneous in quality, these shall form part of the composite
sample
.
e)
However, if grains of different or heterogeneous quality were found filled in any one
sample
bag, sampling shall be done in all bags (100%).
Sample
s of different quality shall be segregated and
sample
s shall be drawn separately.

sample
shall be collected from a given grain box. It
shall constitute as
representative sample
of the lot contained in the box.
4.3
Where the grain lot of same quality (grade) are contained in several
rice boxes, the
sample
s drawn from these boxes shall constitute the

representative sample
shall be thoroughly mixed and reduced to obtain three 100-gram samples and one 500-gram sample by means of mechanical divider or by quartering.
1.2
The first 100-gram sample shall be tested for
moisture content
, the
second 100-gram sample for quality, foreign matter and type
classification; the third 100-gram sample for chalky and immature
kernels and discolored kernels.
1.3
Moisture in
Palay
. Moisture shall be determined by using a properly calibrated moisture tester or by the
standard
oven-method or by any other method which given equivalent results. The weight of the working sample for
moisture content
determination may be increased depending on the requirement of the moisture tester,. Likewise, the sample shall be free from impurities which would greatly affect the reading of the moisture meter.
1.4
Purity
of
Palay
and Foreign Matters
. From the second 100-gram
palay
sample, separate the weed seeds and other foreign matters by
hand picking or by means of a dockage tester or hand sieve. Weight
the separated materials and express the weight as percent
weed
seeds and other crop seeds
and percent other foreign matters. The
weight of the remaining pure play grains shall be expressed as
purity
.
1.5
Type Classification
. Dehull the pure
palay
obtained from the
purity
determination by means of a laboratory huller, or a hand sheller.
Select 10 whole kernels at random, measure the individual length
of the kernels and compute the average length.
1.
6
Other Defects
. Dehull the third 100-gram sample of
palay
by means
of a laboratory huller or hand sheller. Separate from dehulled grains
by hand picking chalky and immature kernels. Weigh separately
such kernel and express the individual weights in percentage.
1.7
Odor and Insect Infestation in
Palay
. The
palay
is considered to be
infested if the 500-gram sample:
contains more than one (1) weevil, or
contains one weevil and any other live insects, or
does not contain any weevil but contains five or more other live insects.
Insect infested
palay
shall be graded and designated according to the grade requirements of the
standard
but the word
infested
shall be added as part of the grade designation.
The 500-gram sample shall also be examined for mustdy or sour odor or any objectionable foreign odors which include those from fertilizers, hides, oil products, smoke, burnt
palay
and decaying animals and vegetables matters. Such
palay
shall be downgraded and designated as Off-Grade Grade. Likewise, a chemical test shall be made on the sample to determine possible contaimination of toxic materials.
2. In determining the quality characteristics and grade of
milled rice
, the following procedures shall be adopted:
2.1
Moisture Content
Determination
.
Moisture content
shall be
determined by using properly calibrated moisture or by the standard air-oven method or any other method which gives equivalent results. Samples for
moisture content
test must be placed in air-tight or moisture proof container at the time of sampling.
2.2
Insect Infestation in
Milled Rice
. Insect infested rice shall be
graded and designated according to the grade requirement of this
standard
, but the word
infested
shall be added as part of the
grade designation. The rice is infested if any one or more of the
following conditions are found from the portion of the sample weighing not less than 50-grams:
contains more than one (1) weevil, or
contains one (1) weevil or any other live insects, or
does not contain any weevil but contains five (5) or more other live insects.
2.3
The determination of
head rice
,
brokens
and
brewers
shall be made or
working sample weighing 100-grams. All other determinations
except that of paddy shall be made on a duplicate working sample weighing 100 grams.
2.4
Type Classification
. Using the headrice obtained from the headrice
determination in 2.3, select 10 whole kernels at random. Measure the
individual length of the kernels and compute the average length.
2.5 The Staining Method.
a)
Prepare the alkohol-alkali staining solution as follows:
KOH (potassium hydroxide). Dissolve 20 gm of KOH (pellets AR grade) in 1.0 liter distilled water.
Mixed with ethyl alcohol (EtOH absolute AR grade) in the volume ratio 1:3. Shake well.
Mixed with ethyl alcohol (EtOH absolute AR grade) in the volume ratio 1.3. Shake well.
b)
Secure a five hundred (500) grams composite sample of
milled rice
from the lot to be tested.
c)
Separate the headrice from the
brokens
manually or using indented plates, if available.
d)
Prepare the working sample for three trials consisting of 100 pieces
head rice
kernels per trial, using a grain counter, if available.
e)
Place the kernels (100 pieces) in a petri dish and pour twenty milliliters (20 ml) of 2% KOH-EtOH solvent in the dish, or just enough amount of staining solution to soak the kernels.
f)
Allow to stand for 15 to 30 minutes.
g)
Pour-off and discard the staining solution.
h)
Transfer the stained
head rice
sample on a sheet of white bond paper and air-dry for about 5 minutes.
i)
Separate and count the stained kernels with residual
bran streaks
whose length is at least 1/6 of the total length of the grain which is averaging in
size
at six (6) mm. Stained kernels appear as a light yellow endosperm while the residual
bran streaks
are highlighted as distinctly brown.
j)
Count the kernels with
bran streaks
. The count corresponds to the percentage of the kernels with
bran streaks
(BS) in a working sample.
Number of Kernels with BS = % Kernels with BS
k)
Refer to the following table for the corresponding milling degree:
