references, only the edition cited applies. For undated references, the latest edition of the 
referenced document (including any amendments) applies. 
 
3. Materials 
3.1 Nettings 
3.1.1 The nettings shall be made from polyamide, polyester or any other synthetic materials. The 
denier of multifilament yarns as specified above shall be within ± 10 percent tolerance when tested by 
the method given in BDS 1221. The mesh of the netting shall normally be hexagonal. However 
square or round mesh may also be used, if required by the buyer. No. of mesh may be as specified in 
Table 1 or as agreed.

4. Manufacture and Workmanship 
4.1 Wall and Top 
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 
4.5). One edge of the netting of the wall shall be attached 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 case of 
nets ordered with bottom reinforcement, four tying loops shall be provided at the seam joining the 
bottom reinforcing piece. 
4.4 Stitching 
 
The nets shall be made with lock stitch of even tension throughout and loose ends securely fastened 
off. The number of stitches per decimeter shall be 30 to 38. The stitching shall be made by using spun 
polyester sewing thread of matching shade conforming to the requirements given in BDS 1221. 
4.5 Joined Nets 
The joined nets shall be permitted in maximum 20 percent of the supply and no net shall have more 
than two joints except for X-family nets where 100 percent joined nets in the roof part shall be 
permitted without any restriction to number of joints. However, the width of the panel in the joined net 
shall not be less than 1 m.

6. Marking 
 
6.1 The following information shall be indelibly marked on the cloth label securely stitched at any top 
corner of the net:

5.2 The dimensions of the nets shall conform to those given in Table 2 when determined by the 
methods prescribed in BDS ISO 22198.  
The Colour/Shade of nets shall be as specified in the contract or order. In case a sample has been 
agreed upon and sealed, the supply shall be made in conformity with that sample in such respects.
The following information shall be indelibly marked on the cloth label securely stitched at any top 
manufacture;

6.3 BSTI Certification Marking 
 
6.3.1 The mosquito net s may also be marked with the BSTI Certification mark. 
 
NOTE - The use of the BSTI Certification Mark is governed by the provisions of Bangladesh Standards 
and Testing Institution act, 2018, and the Rules and Regulations made there under. Details of conditions under 
which a license for the use of the BSTI Certification Mark may be granted to manufacturers or processors, may 
be obtained from the Bangladesh Standards and Testing Institution. 
 
7. Packing 
 
The mosquito nets shall be packed as stipulated in the contract or order. However, a recommended 
procedure is given below: 
25 to 50 mosquito nets depending upon size shall be placed one over the other and tied with a twine 
or rope of 2 to 3 mm dia. made of cotton or polyester or polyamide to form a bundle. 2 to 4 such 
bundles shall be wrapped in low density polyethylene film (LDPE) of minimum thickness of 40 microns 
or in any other suitable material as agreed to between the buyer and the seller to form a bale. The 
bale shall be stitched by HDPE or nylon twine/rope such that the nets do not get pierced and the bale 
remains intact after packing without damaging the mosquito nets during handling or storage. The bale 
shall be strapped along with clips. 
7.1 The Package may also be marked with the other requirements as specified under the ‘Packaged 
Commodities Rules, 2021 of BSTI. 
 
8. Sampling and Criteria for Conformity 
 
8.1 Lot–– The quantity of mosquito nets of same type, variety and mesh size delivered to a buyer 
against one dispatch note shall constitute a lot. 
8.2 For assessing the conformity of the lot to the requirement of this standard, the sample as given in 
col. 2 or col. 3 of Table 3 shall be drawn at random from the lot. To ensure the randomness of 
selection, method given in BDS 1765 shall be followed.
