 Foreword  
This Draft Tanzania Standard is being  prepared by the Paints and V arnishes Technical Committee 
under the supervision of Chemicals Divisional Standards Committee and it is in accordance with the 
procedures of the Bureau.  
During the preparation of this standard reference was made to Indian  Standard IS 6350 :2003  
Specification for Shoe cream , published by Bureau of  Indian Standards . 
 
For the purpose of deciding whether a particular requirement of this standard is complied with, the 
final value observed or calculated expressing the result(s) of a test or analysis shall be rounded off in 
accordance with TZS 4 .  CDC 13 (935) DTZS

The container  shall be labelled  either in English, Kiswahili or both as agreed between the manufacturer 
and the supplier  with the following information:  
a) the name of the product  
b) manufacturer's name and physical address;  
c) registered trade mark if any ; 
d) colour of cream  
e) net content;  
f) batch/code number;  
g) country of origin;  
h) date of manufacturer  and best before date;  
i) safety precaution  
j) instructions for use and storage . 
6. Sampling  
Sampling shall be done in accordance with TZS 524

 Annex A 
(normative)  
Ash content  
A.  1 Scope  
These methods determine the ash contents in waxes, polishes and other related materials.  
A.2 Procedures  
A.2.1 Method A  
Melt a portion of non -volatile matter, and stir thoroughly. Accurately  weigh  a mass of a 3 g sample 
(to the nearest mg) in a tarred crucible. B urn off the combustible  matter slowly and ignite the 
residue to constant mass at a 700 ºC . 
Ash content , percent =  mass  of residue
mass  of sample ×100 
A.2.2 Method B  
Weigh  a mass of sample (to the nearest mg) containing about 2 g of non -volatile  matter in a  tarred 
porcelain crucible. Evaporate the volatile matter and burn the combustible  matter slowly by 
igniting to constant mass.

 Annex B 
(normative)  
Determination of pH of water extract  
 
 
B.1 Add 15 g of the material to 100 ml of distilled water in a  beaker.  
 
B.2 Heat while stirring till all the wax is melted.  
 
B.3 Allow to cool to a  temperature of 27  °C ± 2 °C.  
 
B.4 Separate the aqueous layer and determine its pH using a pH meter with a glass electrode

 Annex C 
(normative)  
Test for Resistance to Heat and Cold  
 
C-1.1 General — The test is carried out on the shoe cream in its original  containers (glass bottles or 
collapsible tubes). One sample is maintained at 10  °C ± 1°C and another sample at 45  °C ± 2°C for 2 hours.  
C-1.2 Resistance to Heat — The material maintained at 45 °C ± 2°C shall pass the  following requirements.  
C-1.2.1 No objectionable  odour shall emit from the containers when opened.  
C-1.2.2 No cream shall ooze out through the caps of collapsible tubes.  
C-1.2.3 No liquid shall separate from the cream and it shall not flow when  the container is tilted. Separation 
of a few drops shall not be considered a  failure if these are reabsorbed into the cream on cooling.  
C-1.3 Resistance to Cold — The material kept at 10  °C ± 1°C shall pass the  following requirements.  
C-1.3.1 The material shall spread on leather without crumbling when applied  with a brush.  
C-1.3.2 No liquid shall separate.

 Annex D 
(normative)  
Method for Testing Free dom  from Gritty  
 
D.1 Take a small amount of cream between fingers and rub.  
D.2 No p resence of lumps or granules shall be felt.  
D.3 Take two clean, dry microscopic slips. Apply a uniform thin coat of the cream on the surface of one. 
Immediately place the other slip on it so that the wet polish layer is sandwiched.  
D.4 Pressing the two slips gently with fingers, cause them to move rela tive to each other a few rounds. 
Separate the slips by sliding off.  
D.5 There shall not be any streaks in the cream  coat on either slip.
