Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and 
Cooperatives established under Cap 327, of the Laws of Uganda, as amended.  UNBS is mandated to co-
ordinate the elaboration of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO). 
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of representatives of 
consumers, traders, academicians, manufacturers, government and other stakeholders. 
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
This Draft Uganda Standard, DUS D EAS 355: 2015, Stain remover for tableware — Specification , is identical 
with and has been reproduced from a n East African  Standard , DEAS 817: 2015, Stain remover for tableware  
— Specification , and is being proposed for adoption  as a Uganda Standard.  
Wherever the words, “ East African Standard" appear, they should be replaced by "Uganda Standard."

 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.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community. 
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 always have the latest versions of the standards 
they are implementing .

6.2 Record the average and multiply by the number of sheets in each roll DRAFT UGANDA STANDARD ON PUBLIC REVIEWDEAS 355: 2015 
© EAC 2014  – All rights reserved  7 
 6.6.4 Freedom from holes 
While carrying out 6.6.3 , check for compliance with 4 .5 
6.7 Assessment of perforations 
Use the five rolls taken in accordance with 6.4 at a position chosen at random on the roll under test, detach a 
sheet by holding it between thumb and forefinger at its perforated end and exerting a steady pull at an angle 
of about 10o to the edge of the roll, and check the tear for compliance with 4.6.2d). Carry out the test on 10 
consecutive sheets of the roll, and then repeat the test on the remaining four rolls.  Record (separately) the 
number of defective (i.e. perforations which do not tear satisfactorily) found in the 10 tests on each  roll. 
6.8 Tensile strength 
6.8.1 From the rolls taken in accordance with 6.4 and observing the precautions given in ISO 1924 for 
preparing specimens for test cut at random 10 specimens in the machine direction and 10 specimens in the 
cross direction of the paper, each specimen being at least 100 mm long and 50 mm ± 0.1 mm wide. 
6.8.2 Use the apparatus and procedure given in ISO 1924 but 
a) use an initial distance of 65 mm between the clamps 
b) use a rate of loading such that the specimens break within + 5 s. 
6.8.3 Calculated and report to three significant figures the average breaking strength in Newton’s per metre 
of width for each direction of the paper and also the average of that strength in the two directions. 
6.9 Softness 
6.9.1 Apparatus: An instrument that measures the combination of resistance due to surface friction and 
flexural rigidity of sheet material when forced by a blade through a slot that has parallel edges and a width of 
6.35 mm. 
6.9.2 From the rolls taken in accordance with 8.4 cut at random 20 test specimens (i.e. 10 pairs) each of 
size 100 X 100 mm with the adjacent edges parallel to the machine and cross directions respectively. 
6.9.3 Calibrate the instrument according to the manufacturer's instructions.  Place a pair of specimens next 
to each other and centrally over the slot with their cross directions parallel to the slot.  Start the blade 
mechanism and record the maximum reading.  Turn the two specimens through 90o so that their machine 
directions are parallel to the slot.  Again record the maximum reading.  Repeat the procedure on the remaining 
nine pairs of specimens ensuring that an equal number of tests are performed on each side of the paper.   
Calculate and report to three significant figures the average of all reading in milli newtons as the softness of 
the paper.  
7 Conditions of acceptance 
The lot is acceptable if the aggregate percentage failure for all the requirements does not exceed 5 %
