 FOREWORD  
 
This Bangladesh Standard was a dopted by the Bangladesh Standards and Testing Institution 
on 21 April 2014  after the draft had been thoroughly discussed and approved  by the Textile 
Products Sectional Committee and  then finally approved by the Jute and Textile  Divisional 
Committee.  
 
Synthetic mosquito nets are finding wide acceptance in providing effective protection against  
mosquito attacks in view of smaller mesh size. Further these are lighter in weight, durable, 
odorless, non -staining and abrasion resistant with no chances of rott ing and need minimum 
care in use. These can also provide effective ventilation of air without suffocation.  
 
This standard covers two mesh sizes of mosquito nets. Mesh size of 156 provides the best 
combination of ventilation and protection against mosquito attacks in hot climates while 
mesh size of 196 is more suitable for cold climates.  
 
In the preparation of this standard considerable assistance has been derived from the 
following publication:  
 
          IS 14953:2006 Textiles – Polyester or Polyamide Mosq uito Nets – Specification(First  
                                   Revision), 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 of a test or analysis when 
applicable, shall be rounded off in accordance with BDS 103 -2001 "Rules for Rounding off 
numerical values (Ist revision)". The number of significant places retained in the rounded off 
value should  be the same as that  of the specified value in the standard.

The top shall be made from one piece of netting in case of bed nets meant for single bed and 
single joint piece in case of double/family/X - family bed nets. The walls shall be made from 
one piece of netting and shall be closed with lapped seam  and the seam shall be at one of the 
corners (see also 5.4). One edge of the netting of the wall shall be at tached to the netting at 
the top by means of plain seam as shown in Fig 1.   
 
4.2 Reinforcement at Bottom  
 
If  specified by  the buyer, the bottom of the walls shall be reinforced by  stitching a single 
strip of netting of same fibre, same mass per square meter  and of matching shade as the 
original netting by a lapped seam as shown in Fig.1.  
 
4.3 Tying Loops  
 
The  nets shall be provided with  similar material stitched tying loops respectively at the roof, 
four in case of single nets and six in case of double, family  and X -family nets. The loops 
respectively  at the roof, four in case of single nets and six in case of double, family and X - 
family nets. The loops shall be  12 to 15 mm wide and  made of the same fabric as of the wall 
and top, as shown in  Fig. 1. In cas e of nets ordered with bottom reinforcement, four tying 
loops shall be provided at the seam joining the bottom reinforcing piece.
