 Foreword 
Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Tourism, Trade and 
Industry established under Cap 327, of the Laws of Uganda.  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/SPS Agreements 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 standard has been developed by the Textiles and textile products ’ Technical Committee UNBS/TC 7.

 Annex A  
(normative)  
 
Inspection and Methods of test 
A.1 Inspection of Pillows 
After checking for compliance with the relevant requirements given in Clause 4, visually examine each pillow 
in the sample for compliance with the requirements of 5.2.1  
A.2 Conditioning of pillows 
The fabric should be conditioned according to FDUS ISO 139. 
After carrying out the test given in Clause A.3, cut from the samples the test specimens required for the test 
given in Annex B In the case of the casing fabric, cut from the sample (see Note Clause A.4) the test 
specimens required for the test given in Clause A.4 
A.3 Finished dimensions 
A.3.1 Lay the pillow flat on a plain surface. Gently pat the pillow (without subjecting it to tension) with the 
hands  until it is free from all storage folds and wrinkles. 
A.3.2 Use an accurately graduated steel tape of length greater than the length of the pillow to determine, to 
the nearest 1cm, at approximately three equal intervals in each direction, the width and the length of the 
pillow. 
A.3.3  Calculate the arithmetic mean of each set of measurements and record the results as the width and 
the length, respectively, of the pillow. 
A.3.4  Check for compliance with 4.3 
A.4 Properties of casing fabrics 
NOTE:  Testing for compliance with the fabric requirements given in table 1 requires a length of at least 1m, full width, 
of the casing fabric. 
A.4.1 Composition 
Determine the composition of casing fabrics by chemical analysis in accordance to US ISO 1833-1 
 
.

 Annex B  
(normative )  
 
Determination of mass per unit area 
B.1 Apparatus 
B.1.1  Table that has a smooth flat surface and is of a size that exceeds that of the fabric to be measured 
B.1.2  Pair of scissors or suitable cutter that is capable of cutting a square or circular specimen of area 0.01 
m2 to an accuracy of 1 % or better  
B.1.3  Metal plate that is 5 mm smaller than the cutter and that has a thickness of 10 mm. 
B.1.4  Balance that is capable of determining the mass of the specimen to an accuracy of 0.2 % or in the 
case of 0.01m2 specimens, to an accuracy of 0.001 g 
B.2 Procedure 
B.2.1  Ensure that the Fabric, which should preferably be selected from the middle of a piece, is not less 
than 0.5 m and not more than 4 m long, and lay it flat, and without tension, on the table. Cut at both ends, 
across the full width of the sample, along parallel lines at right angles to the selvedge. If the mass per unit 
area of a selvedge on a full-width piece appears to deviate appreciably from the mass per unit area of the 
body of the fabric, or if so agreed upon between the parties concerned, trim off the selvedge along the 
outermost threads of the body of the fabric and use only the body of the fabric for the determination of the 
mass per unit area. Measure the width and length of the specimen. 
B.2.2  Use the balance to determine the mass of the specimen 
B.3 Calculation 
Calculate the mass per unit area M in grams per square metre, using the following formula. 
M 
wlm
1000000  
where, 
m is the mass of the specimen, in grams; 
l is the length of the specimen, in millimetres; and 
w is the width of the specimen, in millimetres.

D.1.3 Sewing machine: Electrically operated, single-needle, lock-stitch, capable of producing stitch type 301 
and provided with the appropriate throat-plate(s) and feed-dog(s) for use with the sewing threads.  
D.1.4  CRE tensile-strength testing machine, that is capable of constant rate of extension of 100mm/min, 
fitted with jaws. 
D.1.4.1 Of a type that will not weaken the test specimen during test and such that each jaw has a front 
face of size 25 mm x 25 mm and a back face of size at least 25 min x 40 mm. the longer dimension being at 
right angles to the direction of the applied load. 
D.1.5  Transparent template of size approximately 125 mm x 30 mm ruled with three lengthways and parallel 
lines, the clear distance between adjacent lines being 3 mm ± 0.05 mm. 
D.2 Sampling and preparation of test specimens 
D.2.1 Take a laboratory sample as specified in the relevant product specification. 
D.2.3 From the conditioned laboratory sample, cut 10 test specimens each of approximately 200 mm x 75 
mm, so that in five of the test specimens the longitudinal yarns are warp yarns and in the other five test 
specimens the longitudinal yarns are weft yarns. 
D.2.4 Cut the two sets of test specimens so that their longitudinal yarns all represent different threads and, if 
possible different portions of the warp and the weft respectively. Do not cut any warp-direction test specimen 
closer to a selvedge than 8 mm. 
D.2.5 Select the sewing thread and the sewing machine needle size appropriate to the mass per area of the 
test specimen (see TableD.1) and fit the corresponding throat-plate and feed dog to the sewing machine. PUBLIC REVIEW DRAFTDUS 1578 -1: 2014

 D.2.6 Fold each test specimen in half by placing the two shorter ends together and while maintaining a 
constantly sewing speed, sew a row of stitches parallel to and at a distance of 15 mm from the fold at the 
stitch rating (see Table D.1) appropriate, to the mass per area of the test specimen. 
D.2.7 Cut each test specimen on the fold and parallel to the line of stitching so as to provide a seam of width 
approximately 1 mm.  
D.3 Procedure 
D.3.1  Clamp a test specimen symmetrically in the jaws of the CRE tensile-strength testing machine with the 
sear midway between and parallel to the edges of the jaws so that the free distance between the jaws at the 
start of the test is 75 mm. 
D.3.2 Hold the transparent template in front of the clamped test specimen so that its centre line is parallel to 
the line of stitching at the seam of the clamped test specimen and set the CRE tensile-strength testing 
machine in motion. 
D.3.3 Stop the CRE tensile-strength testing machine and record the load, in newtons, when 
D.3.3.1 Any part of the opening of the seam reaches a width of 6 mm (reduced to 32 mm in the case of 
test specimens that have warp threads and weft threads of contrasting colours). 
D.3.3.2 A failure owing to the breakdown of the fabric or sewing thread occurs, whichever occurs first
