 Foreword  
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 mandat ed 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 key stakeholders 
including go vernment, academia, consumer groups, private sector and other interested parties.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments befor e recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
The committee responsible for this document is Technical Committee UNBS /TC 5, [Chemicals and 
Environment ], Subcommittee SC 03, [Plastics and related products ].

 Annex  A 
(normative)  
 
Determination of moisture content of w ood 
A.1 Test Specimen  
The entire block used in the broom , may form the test specimen for the determination of moisture content or 
apiece cut from the test specim en may, as well, be used for moisture content determination. When for any 
reason additional determination of moisture content is required, separate samples shall be prepared from 
the sample material as is used in preparing the test specimens. Smaller speci mens may be used when 
deemed necessary. The test shall be carried out immediately after cutting the specimen . 
A.2 Procedure  
A.2.1  Weigh accurately each test specimen.  
A.2.2  Dry the  specimen  in a ventilated oven at 105 °C ± 2 °C until the weight becomes co nstant between 
two successive weightings made at an interval of not less than one hour.  
A.3 Calculation  
The moisture content, expressed as a percentage of the oven -dry weight;  
 
Where,  
W1 is initial weight in g of the test specimen, and

 Annex B  
(normative)  
 
Determination of pull strength  
B.1 General  
A simple instrument as shown in Fig. B1 can be used for testing the pull strength. This unit is suitable for 
mounting on wall. It consists of dial force gauge / weighing scale (0 -10 kg) operating on spring (A) mounted on 
wooden plate (B). A tubular tuft holder (C) is hung on the hook of dial gauge. A clamp for holding brush (E) is 
provided which is movable downward and upward with a screw (F). The dial force gauge /weighing scale shall 
be calibrated having traceability  
B.2 Procedure  
B.2.1 Fix a brush with bristles in upward direction in the brush holder with the help of sc rew (G).  
B.2.2 Insert all bristles of one tuft  in the hole provided at the bottom of tubular tu ft holder (C). Care should 
be taken not to allo w bristles from adjacent tufts  to enter in to the hole. Fix the bristles firmly with the help of 
screw (D ). 
B.2.3 Adjust the pointer on dial to zero by adjustment of screw (F).  
B.2.4 Move down the brush holder  slowly with screw (F) watching the pointer on dial carefully till it reaches 
5 kg mark and keep it there for 1 min. Then remove the brush from the gadget and exami ne. The bristles of 
any tuft shall not come out during the test.  
Note: The tufts shall not f ail when subjected to a pull by thumb and finger grip or the force required for pulling 
out an individual tuft shall not be less than 50.0 N for 15 seconds  
NOTE  — any other appropriate instrument for determination of the pull strength available may also be  used

 Annex  C 
(normative)  
 
Deter mination of corrosion resistance  
C.1 Procedure  
Submerge all metal components for 7 h in distilled water, then dry them as rapidly as possible at a 
temperature not exce eding 70 °C and examine the surfaces that are required to be corrosion resistant for 
freedom from corrosion.  
C.2 Results  
The surfaces shall show no sign of corrosion

 Annex  D 
(normative)  
 
Sampling and criteria for conformity of the sweeping b rooms  
D.1 Scale of sampling  
D.1.1 lot — In any consignment, all the brushes of the same size and quality shall be divided into groups of 
500 brushes or less and each such group shall constitute a lot. Care shall be taken to ensure that brushes 
included in a lot do not differ in construction as far as possible.  
D.1.2 the conformity of the brushes in a lot to the requirements of this specification shall be ascertained for 
each lot separately. The number of brushes to be selected for this purpose shall be in accordance wit h Table 
2. 
Table .D1 — Scale of sampling sweeping  brooms  
S/N Number of brooms in the lot  
(N) Number of brooms  to be selected  
(n) 
I.  Up to 1 0 2 
II.  11 to 25  3 
III.  26 to 50 4 
IV.  51 to 1 00 5 
V.  101 to 150  6 
VI.  151 to 300  7 
VII.  301 to 500  8 
 
D.1.3 the brushes shall be s elected at random. To ensure randomness of selection one of the following 
procedures, whichever is suitable, may be followed  
a) If all the brushes in a lot are packed in one box, then starting from any brush, count them in any 
suitable order as 1, 2........., up to r and so on, where r is the integral part of N/n ( N and n being the lot 
size and sample size, respectively), Every rth brush thus counted shall be withdrawn to constitute the 
sample.  
b) If the brushes in a lot are packed in more than one box, approxima tely equal number of brushes shall 
be picked up at random from as many boxes as possible so as to obtain the required number of  
brushes as specified in Table D 1. 
D.2 Criteria for conformity  
D.2.1 for declaring the conformity of the lot to the requirements of this specification, all the brushes selected 
according to D.1.2 and D.1.3 shall satisfy the relevant requirements given in clause 4
