 Foreword 
Development of the East African Standards has been necessitated  by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered  when goods and services are exchanged 
within the Community will be removed.  
The Community has established an East African Standards Committ ee (EASC) mandated to develop and 
issue East African Standards (EAS).  The Committee is composed of representatives of the National 
Standards Bodies in Partner States, together with the represent atives from the public and private sector 
organizations in the community.  East African Standards are developed through Technical Committe e s  t h a t  a r e  r e p r e s e n t a t i v e  o f  k e y  
stakeholders including government, academia, consumer groups, p rivate sector and other interested parties. 
Draft East African Standards are circulated to stakeholders thr ough the National Standards Bodies in the 
Partner States. The comments received are discussed and incorpo rated before finalization of standards, in 
accordance with the Principles and procedures for development o f East African Standards.  
East African Standards are subject to review, to keep pace with  technological advances. Users of the East 
African Standards are therefore expected to ensure that they al ways have the latest versions of the standards 
they are implementing
.

 Annex B 
(normative) 
 
Determination of luminance factor 
B1 Principle 
The principle of the method is photoelectric comparison of the luminance of the test paint relative to that of a 
perfect reflecting diffuser. In this standard, magnesium carbon ate or a white tile, calibrated against a perfect 
reflecting diffuser, is used as the reference surface.  
B2. Apparatus and materials 
B2.1 Light source, a tungsten lamp operating at a correlated colour temperature of  2 854 K in a photometer. 
B2.2  Photoelectric cell,  having a spectral sensitivity closely matched to the CIE photo pic luminous 
efficiency function V(λ). 
B2.3  Magnesium carbonate block, calibrated against a perfect reflecting diffuser. Prepare a ne w surface 
immediately before use. B2.4  Calibrated white reference tile , having a CIE value in the range 70 to 95, and a calibration a gainst a 
perfect reflecting diffuser traceable to a national accredited laboratory. 
B2.5  Glass test pannel,  as described in Annex A (for Method 1 only). 
B3. Procedure 
B3.1 Method 1: Test panels 
B3.1.1 Prepare the glass test panel (B2 .5) and apply the paint by the method described in Annex A. 
B3.1.2  Calibrate the apparatus with the light source (B2.1), with the  axis of the incident beam at 45˚ + 1˚ to 
the reference surface (B2.3 or B2.4). Locate the photoelectric cell (B2.2) such that the axis of the cell is at 90˚ 
+ 1˚ to the illuminated reference surface. If using a magnesium carbonate block, calibrate on the mean of 
readings from three different areas. 
Calculate the absolute value M by use of the appropriate calibration factor. 
B3.1.3  Measure the luminance of three different areas of the paint fi lm using the same geometry as in B3.1.2. 
Calculate the mean luminance L. 
B3.2 Method 2: Road trials 
B3.2.1  Clean an area of each non-reflectorized paint stripe (prepared  as described in H2.6) at a distance of 
500 mm + 75 mm from the near sid e kerb, by the method described  in J2.1, and allow to dry. 
B3.2.2  Taking precautions to shield the photoelectric cell from stray  incident light, carry out the procedure 
described in B3.1.2 and B3.1.3, but measure the luminance at on ly one location on the paint stripe. Measure 
the luminance five times, rotating the cell through approximate ly ˚with minimal lateral displacement between 
each measurement.  Calculate the mean L of the five measurements. PUBLIC REVIEW DRAFTDEAS 928-1: 2018

Determination of the softening point 
C.1 Principle 
The principle of this method is to determine the softening poin t of the thermoplastic road materials in 
accordance with Wilhelmi. 
C.2 Apparatus 
C.2.1 Ring,  in accordance with Wilhelmi (see Figure C.1), consisting of a bottom ring half and a top ring half 
with bayonet catch, retaining rod and prominently protruding ni pples 
C.2.2 Beaker , appropriate form for the equipment 
C.2.3 Steel ball mass, 13.9 ± 0.1 g (approximate diameter 15 mm) 
C.2.4 Thermometer, +30 ˚C +200 ˚C graduated in 0.5 ˚C divisions 
C.2.5 Base plate of metal glass  
C.2.6 Mould parting agent , e.g. mixture of glycerine and dextrine in 1:1 ratio 
C.2.7 Knife 
C.2.8 Tongs or tweezers , for holding the ball 
C.2.9 Test liquids , freshly boiled distilled water, glycerine 
C.2.10 Device for heating the beaker , enabling the temperature of the test liquid to be raised unif ormly from 
5 ˚C to 180 ˚C at a rate of 5 ˚C per 60 s ± 5 s and with stirring if necessary to maintain a c onstant heating rate. 
C.3 Samples 
The sample mass shall amount to a pproximately 50 g. Two test specimens shall be tested. 
C.4 Preparation of the ring 
Heat the bottom half of the ring and base plate, thinly coated with the mould parting agent, together with the 
sample to the manufacturer’s suggested softening point + 70 ˚C. 
Fill the bottom half of the ring with the hot material. Place t he top of the ring onto the bottom half so that the 
superfluous portion of the material is pressed out of that whol e of the top half and leave standing for 30 min at 
room temperature (18 ˚C to 28 ˚C). The salient portion of the test specimen is trimmed off wit h the warmed 
knife so that the surface of the test specimen is smooth and fl at. 
Insert the bottom half of the ring into the top half and fasten  with the bayonet catch. The test specimen is now 
firmly clamped between the halves of the ring, and is not capab le of becoming deforming at the edges. PUBLIC REVIEW DRAFTDEAS 928-1: 2018

Figure C.1 — Ring in accordance with Wilhelmi 
C.5 Procedure 
Suspend the ring, after preparation as in Clause C.4, the beake r in such a way that its bottom face is situated 
50 mm above the bottom of the beaker.  Pour the test liquid int o the beaker up to a height of 50 mm above the 
top face of the ring a temperature of approximately 5 ˚C or 30 ˚C respectively according to the test liquid used 
(see Table C.1).  Place the ball in the test liquid but not on the test specimen. Suspend the thermometer in the 
beaker in such a way that its bottom end lies flush with the bo ttom face of the ring, but does not touch either 
the ring or the beaker. 
The type of test liquid and the initial temperature will depend  of the softening point of the sample and are listed 
in Table C.1.

Softening point in accordance 
with Wilhelmi Test liquid Initial temperature 
Up to 80 ˚C Freshly boiled distilled water 5 ˚C 
Over 80 ˚C Glycerine 30 ˚C 
 
NOTE  Freshly boiled distilled water should be used otherwise t he test results may be affected by air bubbles. 
Glycerine is so viscous at temperature below 50 ˚C that streaks are found during the heating process. However the 
prescribed uniform temperature rise ensures that no difficultie s will occur at temperature above 60 ˚C. 
C.5.1 After immersion of the ball, leave the beaker standing for 10 min at room temperature (18 ˚C to 28 ˚C) 
on the beaker heating devise, which has not yet been switched o n. 
C.5.2 After 10 min, place the ball on the test specimen in the middle  of the ring, with aid of tongs or 
tweezers.  
C.5.3 Heat the beaker in such way that the temperature of the test li quid increases uniformly at a rate of 5 
˚C per minute without non-turbulent stirring. Use the first few  minutes to adjust the rate of temperature rise.  
C.5.4 At temperature which is at least 15 ˚C below the softening point of the sample, adjust the rate of t he 
temperature rise with sufficient accuracy to ensure that the fu rther rate of temperature rise from this point 
onwards takes place at 5 ˚C per 60 s ± 5 s.  
C.5.5 Deviations shall only occur within the range of these ± 5 s and  shall even not be compensated during 
the progress of test. 
C.5.6 As the temperature increases, the test specimen becomes more ca mbered in a downward direction 
under weight of the ball. At instant when either the test speci men or ball comes into contact with bottom of the 
beaker read of the temperature at nearest 0.5 ˚C. 
C.5.7 Test the specimen in the second heating process. If the tempera tures measured differ from one 
another by more than the permissible 2 ˚C, the repeat the test on two new specimens. Carry out the test  
procedure within 48 h of test specimen preparation.  
C.6 Expression of results 
Report the mean value of the two measurements rounded to the ne arest 1 ˚C. This represents the softening 
point in accordance with Wilhelmi. Check for compliance with 4. 3. PUBLIC REVIEW DRAFTDEAS 928-1: 2018

(normative) 
 
Determination of binder content 
F.1  Apparatus  
F.1.1  Metal bottle,  having a capacity of between 600 ml and 2000 ml with a wide mo uth and suitable 
closures.  
F.1.2   Rotating machine,  which will rotate the bottle about its longitudinal axis at a speed of 20 r/min ± 10 
r/min.  
F.1.3   Volumetric flasks , of appropriate capacity, e.g . 250-ml, 500-ml and 1000-ml.  
F.1.4  Centrifuge or filtration apparatus,  the centrifuge capable of developing an acceleration of 
25000 m/s2 ± 100 m/s2 calculated in accordance with the following equation:  
a = 1 .097 n2 r x 10-5 
where,  
n  is the number of revolutions per min;  
r  is the radius (in mm) to the inside base of the tube when rot ating.  
The tubes shall be closed with caps to prevent loss of solvent during centrifuging.  
NOTE 1  A typical centrifuge suitable for this method carries two or more buckets fitted with centrifuge tubes of 
between 50 m Land 100-ml capacity.  
NOTE 2  It is strongly recommended that the speed of rotation s hould be verified regularly to ensure that the centrifuge 
maintains its performance at all times.  
The filtration apparatus comprises a metal bottle as specified in F.1.1, a porous filter thimble, tubing and a 50 
mL burette. The porous filter is of porcelain, alumina or simil ar material, 90 mm long by 20 mm diameter and 
of up to 4 µm pore diameter. The filter is closed by sealing in , to within 5 mm of the bottom, a length of metal 
tubing, approximately 300 mm long by 5 mm bore, that passes thr ough a supporting ring of cork or metal that 
is mounted just inside the open end of the filter. A cement paste composed of copper oxide powder, prepared 
by the direct oxidation of copper wire, of about 425 µm particl e size, and phosphoric acid is used to seal the 
joint. The joint is left to dry for a few hours. Alternatively,  a rubber stopper may be used. Care has to be taken 
to ensure that the seal does n ot split the filter thimble.  
F.1.5   Recovery apparatus,  comprising a water bath with an electric heater capable of mai ntaining boiling 
water in the bath throughout the recovery procedure, a flat bot tomed flask of 200 mL or 250 mL capacity, a 
vacuum gauge, a vacuum reservoir and a means of maintaining reduced pressure, e.g. a filter pump.  
F.1.6   Balance, capable of weighing to within an accuracy of 0.005 g.  
F.1.7   Solvent, Use dichloromethane (methylene chloride), complying with BS 1994.  
F.2  Procedure  
F.2.1  Take a sub sample of 100 g to 150 g as described in Annex B break it into small pieces, and weigh to 
an accuracy of 0.05 % of the total mass taken.  PUBLIC REVIEW DRAFTDEAS 928-1: 2018 
16 © EAC 2018 – All rights reserved
 F.2.2   Insert the pieces into the bottle and add dichloroomethane, m easured by means of volumetric flasks, 
to give a solution of the binder having a concentration of abou t 3 %.  
F.2.3  Close the bottle and rotate it on the rotary mixer for a minim um of 15 min, until a complete solution of 
the binder is obtained.  
F.2.4   Separate a portion of the binder solution from insoluble matt er either by centrifuging for 20 min to 
30 min in completely closed tubes, or by means of the filtratio n apparatus using a dry, binder free filter. Take 
care to minimize loss of solvent during this separation.  
NOTE 1  If filtration is prolonged, owing to fine mineral matte r being present in the binder solution, inaccurate results 
may be obtained and in this case centrifuging is essential.  
NOTE 2  When the amount of binder in the sample is unknown, it is advisable to recover the binder from one aliquot 
portion of solution before proceeding with the duplicate recove ry. 
F.2.5   Weigh two flat-bottomed flasks  (see F.1.5) to the nearest 0.0 1 g.  
F.2.6   Measure from the burette a sufficient amount of the centrifug ed or filtered solution into each flask to 
give a residue of 0.75 g to 1.25  g of binder after evaporation of the solvent.  
NOTE  An estimate of the volume of solution (aliquot portion, A  (in mL)) required is given by the following equation:  
8 x 100 A = C x D   
where,  
8  is the total volume of solvent (in mL); 
C  is the mass of sample (in g);  
D  is the estimated percentage of soluble binder in the specime n.  
F.2.7   Remove the solvent from the binder solution by connecting eac h flask to the recovery apparatus. 
Immerse the flasks to approximately half their depth in the boi ling water, and distil off the solvent at 
atmospheric pressure or at a reduced pressure of not less than 600 mbar (1 mbar = 0.1 Kpa = 102 N/m2). 
While the distillation is proceeding shake the flasks with a ro tary motion so that the binder is deposited in a 
thin layer on the walls of the flasks. Do not allow pressure ab ove atmospheric to develop in the flask during 
the evaporation of the solvent.  
F.2.8  At the stage that relatively rapid reduction in pressure occur s, usually accompanied by frothing, when 
the bulk of the solvent has been removed, reduce the pressure t o 200 mbar in 1.5 min and maintain the 
pressure at 200 mbar for a further 3.5 min.  F.2.9   Remove the flasks from the bath and admit air to the apparatu s to increase the pressure to 
atmospheric. Wipe each flask dry and disconnect it, taking care  to prevent the entry into the flasks of any 
water that may have collected where the rubber stopper joins th e flask. Remove the last traces of solvent that 
remain in the flasks by a gentle current of clean, oil and wate r free air.  
F.2.10   Cool the flasks in a desiccator and weigh them to the nearest  0.01 g. If the quantity of soluble binder 
recovered in either flask lies outside the limits 0.75 g and 1. 25 g, repeat the recovery with another portion of 
the solution having the volume suitably adjusted.  
F.2.11  If the difference between the duplicate recoveries is greater than 0.02 g, reject these results and 
repeat the recovery of the binder  in duplicate on further aliquot portions.  
F.2.12  Note the results of the duplicate determinations in which the mass of binder recovered lies within the 
required limits.  PUBLIC REVIEW DRAFTDEAS 928-1: 2018

 F.2.13  When the aggregate is required for a grading test or for analy sis, filter the whole of the solution 
remaining after determination of the binder content. Use the fu nnel method described in BS 598 : Part 2, but 
with a No. 40 Whatman filter paper or equivalent or using a sin tered glass Buchner funnel (porosity No.4) or a 
pressure filter.  
F.3  Calculation of results  
F.3.1   Calculate the mean of the results obtained in F.2.11.  
F.3.2  Calculate the binder content C  (% by mass) of the sample from the following equation:  
 
where,  
m is the mass of sample (in g);  
z  is the average mass of binder r ecovered from the two aliquot portions (in g);  
V  is the total volume o f solvent (in ml);  
V  is the volume of each aliquot portion (in ml);  
d  is the relative density of the binder.  
NOTE The density of resin/oil binders containing between 20 % a nd 30 % of oil lies between 1.03 and 1.08, hence a 
figure of 1 .05 may be assumed when the exact nature of the bin der is not known.  
F.4 Test report  
Report the binder content of the sample.   PUBLIC REVIEW DRAFTDEAS 928-1: 2018

 Annex G 
(normative) 
 
Determination of the grading of constituents and glass bead con tent 
F.1 General  
This Annex describes the methods for determining the grading of  the constituents and the glass bead content 
of marking materials sampled in accordance with Annex B for the  whole of the material obtained as described 
in Clause C.2.  
F.2 Apparatus 
2.80 mm, 600 µm and 425 µm test sieves complying with BS 410 sh all be used.  
F.3  Determination of grading of constituents  
F.3.1   Ignite the filter paper and thoroughly mix the ash with the m ain bulk of the aggregate.  
F.3.2   C a r r y  o u t th e  g ra d in g  t e s t  u s i n g  2 . 8 0  m m  a n d  6 00  µ m  t e s t  s i e v es in accordance with the method 
specified in BS 812 Part 103. If the glass bead content is to b e determined use a 425 µm  test sieve also.  
F.3.3   Report the mass passing each sieve as a percentage of the combined mass of the aggregate, 
pigment and extender and (where present) glass beads.  
F.4  Determination of glass bead content 
F.4.1 Apparatus  
F.4.1.1  Metal tray,  of approximate dimensions 150 mm x 355 mm inclined at an angle  o f  5 ˚  ±  1 ˚  t o  t h e  
horizontal.  
F.4.1.2  Brush, small and soft.   
F.4.2  Method  
Take all the material obtained in F.3.2, place increments of 5 g to 10 g on the upper end of the tray and gently 
brush the material until all the glass beads have been moved to  the bottom of the tray.  
F.4.3  Calculation and expression of results  
Report the total mass of the round glass beads collected as a p ercentage of the mass of the original sample of 
thermoplastic material x 100/70.  
NOTE 1 The accurate determination of the proportion of glass beads in the mixture can be complicated by the chemical compositi on 
and relative density of the materials in it. The method given a bove is the simplest and although rather tedious does give quit e accurate 
results.  
NOTE 2 The intention of this standard is that a minimum of 20 %  glass beads complying with as EN 1423 should be incorporated i n 
the mix at the time of manufacture.  
NOTE 3 An alternative method for determining glass bead content  is to use a round meter as described in EN 1423 PUBLIC REVIEW DRAFTDEAS 928-1: 2018
