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 DEAS 966: 2019, Hair extensions  — Specification , is identical with and has 
been reproduced from an International Standard, DEAS 966: 2019, Hair extensions — Specification , and is 
being proposed for adoption as a Uganda Standard. 
The committee responsible for this document is Technical Committee UNBS/TC 5,  Chemicals and 
environment , Subcommittee SC 1,  Industrial and public health chemicals.  
Wherever the words, “ East African Standard " appear, they should be replaced by "Uganda Standard."

 Foreword  
Development of the East African Standards has been neces sitated 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 Committee  (EASC)  mandated to develop and 
issue East African Standards  (EAS) . The Committee is composed of representatives of the National 
Standards Bodies in Partn er States, together with the representatives from the public and private sector 
organizations  in the community .  
East African Standards are developed through  Technical Committees that are representative of key 
stakeholders including government, academia, c onsumer groups, private sector and other interested parties. 
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 o f standards, in 
accordance with the Principles and procedures for development of East African Standards. XXXXXX.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expec ted to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible  for this document is Technical Committee EASC /TC 071, Cosmetics and related 
products .

 Introduction  
Hair extensions are human or artificial hair utilized for the integration with one's natural h air. Hair extensions 
can alter one's appearance for long or short periods of time by adding further hair to one's natural hair or by 
covering the natural hair all together with human or synthetic hairpieces. Weaving additional human or 
synthetic pieces can  enhance one's hair by giving it volume, length and adding color without the damage of 
chemicals or adopting a different hair texture than that of their own .

meant to enhance or cover the natural hair or cover baldness  
3.3  
braids and hair pieces  
hair strands, usually loose in nature, used as attachments in order to elongate the hair. They may be wavy, 
curly, or s traight and can either be used with hot water or cold (room temperature) water to style them.  
NOTE — A braid (also called plait) is a complex structure or pattern formed by intertwining three or more strands of 
flexible human hair.

 Annex  A 
(normative)  
 
Differentiation or fibre burn test  
A.1 Introduction  
Most obvious way to determine if hair is real or fake is to conduct a microscopic test to find out the chemical 
composition of the extension hair.   However, since most of us do not have a microscope readily available or 
have a degree in forensic science this is  probably not a  suitable option.  
A.2 How to test if hair is human or synthetic  
The textile industry conducts what is called a “fibre burn” test to identify the content. The same test can be 
done on hair.  
1. Remove single strands of hair from different areas of the questiona ble unit.  
2. Hold a single strand with tweezers and use a lighter to keep a steady flame.  
 
NOTE  Do not use matches as they will mask the odour . 
3.  Pay attention to the odour , ember and flame.  
A.3  Results  
A.3.1  Human hair  is a protein fibre that burns wit h a small flickering flame and will not continue to burn 
unless you hold the flame continuously to the strand. It burns briefly with an orange flame and then chars 
leaving a dark ash that turns to powder when crushed. The odour  is of burning flesh or burni ng feathers.  
Synthetic fibres  are either nylon or polyester and each burns quite differently.  
A.3.2  Nylon fibres  burn briefly but rapidly and then melts. It has a sparkling flame that has a blue base 
and orange tip. The ash is like hard amber beads. The odour smells like boiling green vegetables or burning 
celery.  
A.3.3  Polyester fibres  burn and melt quite rapidly at the same time. It has an orange sputtery flame with 
black smoke and gives off a sweetish odour . The ash drips and is sticky to the touch bef ore forming into hard 
black beads. Remember to burn test each fibre separately as your piece may contain a blend of both human 
hair and synthetic.  
A.4  Report  
 DEAS 966: 2019  
© EAC 2019 – All rights reserved  5 
 If the hair burns with a white smoke and turns to ash, it indicates it is human hair and no syn thetic fibres  have 
been added to the bundle. If the hair burns with a black smoke and turns into a sticky texture, it indicates that 
synthetic fibres  have been added to the hair bundle.  DEAS 966: 2019

 Annex B  
(Normative)  
 
Stitch width test  
B.1 General  
 
This test is int ended to ensure that strands of hair do not come out during the normal combing exercise. This 
is usually determined by the manner in which stitching is done.  
It measures the total width per given length.     
B.2 Apparatus  
Metre rule  
B.3 Procedure  
Lay the  weave on a flat surface and measure the width of the stitch. Count the stitches in 1 cm length. Repeat 
five times and obtain an average.  
B.4 Reporting  
Express the result to the nearest whole number.  DEAS 966: 2019

 Annex D  
(normative)  
 
Strand diameter  
D.1 General  
The objective of this test is to ensure that the hair extensions are not having diameters too large than those of 
the natural African hair.  
D.2 Apparatus  
Projection microscope (CH-9435)  
D.3 Proce dure  
Take a strand of hair and place it under the projection microscope and proceed to take the readings in 
accordance with the manufacturer's manual. Repeat the procedure for at least five strands and calculate the 
average.
