Notice:
1. Sand and other abrasive materials as well as other mecha-
nical impurities are not admitted,
2. Test of corrosity is performed on steel plates.
3. The grease can have a smell of a mineral oil.
The smell of kerosene is not admitted.
4. A grease which is used as a softening agent for rubber
mixtures must not have a rest after filtration of the melt-
ed grease through a sieve which has 1600 meshes on 1 cm2.
5. When determining the drop point the grease is not put
into the capsule directly; it is heated to 100% and poured
into the capsules by drops; the capsules are placed on
the bottom of a turned over china cup, which is filled
from inside with crushed ice. A capsule filled up to its
top is left on the bottom of the dish for 20 minutes.
6. For determination of the stability of globule pieces of
the grease we put a spatule a piece about 1 ccm of grease
on a glass plate, so that we move the spatula on the edge
of the glass plate perpendicularly to its surface.
The plate is then fixed vertically into stative, so that
the grease is on the upper surface of the plate.
The stative with the glass plate is put into a thermostat
in such a manner that the plate doesen;t touch the walls
and we leave it now for a 15 minutes at a temperatur$ of
20?C. After this period the piece of grease should have
such a form as when put on the plate and must not slide or
flown down from the plate.
7. For determination of the solubility in petrol we solve the
grease in a four fold amount of anhydrated petrol with
the beginning of destillation at a temperature of minimum
60 C; at this temperature the grease must form a transparent liquid.
8, Package, marking, storage transportation and overtaking
of grease is performed in accordance with standard 1510-50.
9. Sampling if grease is performed in accordance with standard
2517-52. For a control sample we take one kilogram of grease.
Standard 1033-51

4, The test of thermal stability is performed on a sieve with
6400 meshes on 1 cm2; the sieve which has a dish-like small
pit of a capacity of a 50 ml vessel, into which we weight
lo gr of the grease with an accuracy of 0, 1 g.
he sieve with the grease is placed on the vessel and put
into a thermostat, where we keep it for two hours at the
tempatarure of 110't 1"C. The grease is boserved as sus-
taining the test if after two hours there occure no oil in
the vessel
5. Test for chemical stability is performed in a metal box of
a dimension of 50 x 100 mm and a height of about 100 mm,
which we put by a spatula the tested grease, whose surface
is carefully smoothed. The box with a grease is put into
the thermastat heated to 100 t 3?C for 72 hours. The se-
cond box filled as given above and tightly closed by a lid
is put for 72 hours into a dark place of a temperature of
20-25 ?C. After the testing period is over, both boxes
ate put on an illuminated place and both samples are compar-
ed. We consider tested grease as sustaining the test if on
the surface of the sample we observe no films or crusts;
and if it is just a bit darker, than the sample in the other
box,
6. Packing, marking, storage, transport and receiving of grease
is performed accodingly to the standard 1510-50.
7. The taking of samples is carried out accordingly to the
standard 2517--52. As a control sample we take 1 kg of the
grease,

TAKING OF SAMPLES
This standard is related to methods of aampling of nafts pro-
ducts and for testing whether they corrospond to the standards
and technical conditions.
I. The Apparatus For Sampling the Naphta Products
1. For taking of liquid samples of naphta products from tanks
and cisterns we use the following equipment:
a) An apparatus for taking of samples which consists of a
metalic vessel with a heavy bottoku and with an easily
opening lid of a glass bottle, which is put into a metal-
lic frame, The bottle is tightly closed by a stopper,
to which a string is fastened.
For the characieristics of the lowest layer of naphta
we use the apparatus which makes possible to thke samples
3-5 cm from the bottom.

b) A metallic ruler with a load.
2. For taking of samples of liquid naphta products from smaller
vessels (barrels., cans, bottles) we use a glass tube of
a diameter of 10-15 mm with a narrow drawn end.

3. For the taking of solid and powder type samples of naptha--
products we use the screw-like sample gauge
of a length of 400 mm (when taking samples from sacks,
cans or flasks) or of 800 mm length ( when taking samples from
barrels and drums)'
To the downside end of the piston samples guage type along
its diameter a wire is soldered.
4. For taking solid samples of naphta-products we use a knife
(for melting naphta-products)and a shovel (for not melting
products)?
II_ Common directions for taking of samples
5. In order to determine whether the samples of the naphta-
products satisfy the standards and technical conditions,
they are taken in amounts given in the standard and
technical conditions for naphta-products.
in case of necessity of a repeated checking of one or
two quality indexes (whether they correspond to the re-
quirements of the given standards or technical conditions)
We take a sample in and amount that is necessary for per-
forming tests for these indexes.
6. From little vessels samples are taken in a place which is
protected against dust and atmospheric effects.
7. Instruments, as well as vessels for taking of samples must
be clean. Before use they are washed through by the product
from which the sample is taken in case that the product is
liquid. If the tested product is greasy or solid, the vessels
are washed out with petrol and dried.
8. All samples which must be mixed in order to obtain an avera-
ge sample are taken by the same sampling device, without
washing it before taking of each single sample.
After use, the appatates for taking of samples as well as
vessels into which the samples were put are washed out with 50X1-HUM
petrol, dried out and placed to a closed place protected
against dust and atmosphere moisture.

9. For the characteristics of the quality of a naphta-product
in vertical as well as horizontal tanks of a diameter great-
er than 2500 mm we mix samples taken from three layers:
a) 200 mm under the level of the naphta-product (upper lay-
er,
b) from the middle layer
c) from a layer that is lower by 100 mm than the lower edge
of the mile

If the millet and outlet tube does not exist, or in the case
that this tube is nearer than 350 mm from the bottom of the
tank we take the sample in a sistance of 250 mm from the bottom.

10, Samples from a horizontal tank of a diameter up to 2500 mm
are taken accordingly to par. 16 of this standard in the same
manner as samples are taken from cisterns wagons with four
axles.
From a horizontal tank of a diameter greater than 2500mm,
filled by half its capacity, an average sample is formed by
3 parts taken from the middle part of the liquid and by one
part of a sample taken 100 mm below the lower edge of the
milet outlet tube.
11. Before taking the samples the tank must be prepared for de-
livering of the naphta-products.
When taking a sample with a sampling device, the latter
tightly closed, is dipped into reservoir through the opening
to the level which is given on the calibrated rod. Then the
lid of the sampling device is opened and so the naphta-peo-
duct gets in, this is shown by occurance of air bubbles.
From the sampling device we let the naphta-product out into
a clean dry vessel, which must be than closed hermetically
by a stopper.
The sampling device is dipped again this time into the next
given level without a preliminary washing out in this manner
we take a sample from each level.
When taking samples by a flask, this is dipped into the
naphta-product to the proper level and its corone plug is
pulled out with aid of a string,
If there is no opening in the lid of the tank it is possible
to take samples fror all sampling cocks along the whole
height of the product in equal amounts.
12, From the taken samples we make an average sample by mixing
them in the proportions given in the table of par. 9.
Samples of petrols are proliminary cooled with water of a
temperature of 0? - 201C and we mix them with caution in
order to preven

IV. Methods for taking samples from tank-ships
------------------------
13. For the characteristics of the quality of naphta products
in the tank-ships loaded by one sort of a naphta-ptoduct
we take samples from at least 25% of the tanks. From 5%
of the tanks placed on the stern of the ship and from 15%
of the tanks placed in the middle part.

Average samples from each tank consists from samples tak-
on from 3 levels:
a) 200 mm below the surface of the naph.-product one part
b) from the middle part of the naphta product three parts
c) from the lowest level where the sampling device can
reach one part.
Samples are taken with the same manner as is given in par.
11 of the present standard.
14. If the ship is loaded with different naphta-products samples
are taken not less than from 25% of tanks, filled with the
same naphta-product, bit at least from two tanks and the
average sample for each tank is formed as described in para.
13 of this standard.
15. For the evaluation of the quality of rest of products is the
ship before its loading we form an average sample from, different
parts of samples of different volumes which were taken from
25% of all tanks.
V. Methods for_taking sa p1es from liquid naphta=,products from-
Z;`i sterns
16. For an evaluation of the quality of naphta-products in
single cisterns which have two axles we take one sample
from the middle of the cistern (i.e. point of intersection
of the vertical line passidg through the centre of the
opening, with the horizontal axis of the cistern), from a
cistern having four axles we take two samples: one sample
200 mm from the bottom of the cistern, the second 200 mm
from the upper surface of the naphta-product and from both
samples we make an average one
Samples are taken in the manner given in par. 11 of the
present standard.
17. For the evaluation of quality of a naphta-product in a train
transport, loaded with the same naphta-product there is tak-
en in accordance with par. 16 of the present standard one
sample from the front cistern (i.e. the cistern which is
filled first out from the naphta pipeline) , and from other
cisterns an average sample is made of equal volumes of
samples taken from each fourth cistern of the transport,
but at least from two cisterns apart from the front cistern
(this is meant for the transport with seven or less cisterns).
In the case that the naphta-products in the front-cistern
is not of a standard cuality we take and analyse samples
from the second cistern and so on.
For the evaluation of the quality of a naphta-product in
a transport with munbered cisterns an average sample is
made from equal volumes of samples taken from each cistern
of the transport excluding the front cistern, from which

18. If a transport is loaded with fifferent naphta-products
there are taken samples for the evaulation of quality of
each product from each group of cisterns with the given
naphta-product accordingly to par.17 of present standard
in the same manner as given for transport.
VI. Method of taking samples of liquid naphta-products from
PIpe lines
19. For the evaluation of quality of naphta-products flowing
in the pipe-line we form an average sample from equal vo-
lumes of samples taken from sampling cocks on the end of
the pipe-line in the following periods of time:
Total time of puidping
From one to two hours
Periods of time after which samples
are taken
in the beginning and end of the pumping
In the beginning in the middle and in
the end of pumping
From two to 24 hours In the beginning of pumping and after
each hour
More than 24 hours In the beginning of pumping and after
each two hours
The taken samples are nixed in a. dry clean vessel with a
perfect closure.
VII. Amethod of taking liquid samples of naphta-products from
------------------------------
small vessels
20. For the characteristic of the quality of naphta-products
stored in small. vessels we make and average sample from
equal volumes of samples taken in the following amounts
from cans, barrels ,bottles :
a) from barrels --- from 5% of the transported number but
not less than from two barrels
b) from cans, bottles and flasks from 2% of the transported
number but not less than from two cans, bottles and

for each wagon frog 20% of the barrels or cans. Samples
from cans are taken before their soldering, For a repeated
checking of quality of naphta-products stored in soldered
cans not longer than 12 months, we take samples from 5% of
the cans and at a longer storage than 12 months from 20%
of the cans.
Barrels determined for the taking of samples are rolled
forwards and backwards,, then turned so that the stoppers
are on the top; than the surface of the stopper is wipped

by a duster, the stopper is put out and put with the plug
upside beside the opening of the barrel.
Cans and vessels determined for the taking of samples are shaken
and set with their closures upside, the surface around the
opening is cleaned, the covers are put out and placed with their
thinner part upside next to the cans and vessels. Bottles are
shaken and the stoppers are put out.
22. When taking samples by a tube we dip a clean and dry tube with
the naptha product to a depth of 30 cm and the naptha product is let
to flow in; then the upper opening of the tube is closed by our
thumb, the tube is put out and the whole surface is washed through
by the taken product and then the liquid is poured out. Then we
agqin dip the tube inteo the product, fill the tube close it by our
thumb put it out and the taken sample is poured into a clean and
dry vessel.
23. From all barrels, cans, bottles and vessels samples are taken
in the same quantity. The taken samples are poured into a dry clean
vessel and mixed through.
24. After sampling, the barrels, cans, bottles and vessels are
closed with stoppers and lids.
VIII. A Method for taking greasy naptha products from vessels.
25. For the evaluation of the quality of greasy naptha products
enclsoed in small vessels and average sample is put together from
equal volumes of the samples taken from 2% of the number of barrels,
boxes, drums, cans or vessels but at least from two barrels, boxes,
drums, cans or vessels.
26. Barrels, chests, drums, cans or vessels determined for the
taking of samples are turned with their bottoms or lids upside, wiped
by a duster, then lids are put of from the drums or barrels bottom,
the covers are removed from chests, cans or vessels are put with their
inside surface upside next to the barrels, boxes, cans and vessels.
Then a layer of a depth of 5 mm and a diameter of 200 mm is taken away.
27. The sampler is taken by a screwlike or piston-like sampler.
When taking sampler by a screw-like sampler it is driven into the
vessels, drums, cans, barrels or chests till to their bottom, the
probe is then put out, the grease taken away by a spatula; the upper
part of the sample (5mm) from the barrel and k chests is taken away.
When taking samples by a piston sampler this is driven till to the
bottom of barrels, cans, dru;ns, boxes or vesels, turned around by
1800 so that the sample is cut off by the cable, then the probe is
put out and if the sample was taken from barrels or boxes, the upper
part (5mm) is again removed.
28. From all barrls, chests, drums, cans and vessels are taken in the
same quantity samples. The taken samples are put into a dry clean
vessel and mixed with a spade. 50X1-HUM

a flasks, the mixture in the flask is refluxed until the
grease is perfectly solvoed, cooled down to 50-60?C, a few
drops of phenolphtalein are added and the contents of the
flask is left to settle down. If the solution after setting
down has a pink colouring, this shows alcality of t)re solu-
tion, if the solution has not get pink colour, it is to ve
titrated under a strong shaking in a hot state by a 0,1 N
solution of KOH until a slight pink colouring occurs. The
number of acidity (X) in mg of KOH is calenlated by the
following formula:
X * v T 1000,

a'i_ality certificate ',y checking the weight, the state of labeling
of containers of the racking and < f the integrity of the seals. The
oil from defective containers or containers with damaged seals must
be additionaly tested and in case of lack agreement with the spe-
cified standard the it must be r-: iected defective.
IV. Sampling and methods of testing.
12./ After inspectic_n of the outward appearance the the
state of containers and tieir marking the receiver should open accord-
ing tc this choice:
all containers from a batch containing 5 or less rackages, 50 per
cent f containers from a batch containing more than 5 packages.

13./ The container with oil chosen for sampling should be
carefully shaken and frcm each of them an equal quantity of oil
shrild be taken so that the sum total of ail taken for sampling
may not be less than 8:0 g.
The oil-sample is taken by means of a clean, dry cylindri-
cal glass tube with fused brims 15 mm of diameter, inserted through
the seal opening of the andslcwly dipped to the full
denty f the , il.
After fil_l.ing of the glass tube its upper opening is covered
tis-htly by finger, the tube is taken ut of the containe and its
contents is poured into a clean, dry flesk with a capacity of about
1 liter. The initial oil sample is carefully stirred and poured
in equal am opts into two clean, dry bottles with ground or well
fitting stop-ers. One of the samples is sent to laborytory for
control test, and the ether is sealed up and kept not less than
3 months.
1L./ Labeles with the following data are sticked on the
bottles:
a/ the name of the producing factory,
b/ the number and the net weight of the batch,
c/ the date of sampling and of prcduction, the name
of the person which carried out the sampling.
15. / The specific gravity is determined by picncmetric
