 Foreword  
This Draft Tanzania Standard is being developed by the Yarns and Twi nes Technical Committee 
under supervision of the Textile and Leather Divisional Standards Committee , and it is in 
accordance with the procedures of the Tanzania Bureau  of Standards . 
In the preparation of this Draft Tanzania S tandard assistance has been obtained from the following 
standard:  
IS 6347:2003 (Reaffirmed 2019) Texti les — Polyethylene monofilament twines for f ishing 
— Specification         
In reporting the result s of a test or analysis made in accordance with this Draft Tanzania S tandard 
if the final value, calculated or observed is to be rounded off, it s hall be done in accordance with 
TZS 4 Rounding off numerical values.

1.2 It does not prescribe the type of finish and feel of the twines.  
 
2. Normative reference  
For the purpose of this Draft  Tanzania Standard, the following references shall apply. For dated 
references, only the edition cited applies. For undated references, the latest edition of the referenced 
document (including any amendments) applies:  
 
TZS 3, Atmospheric conditions for tes ting. 
TZS 4, R ounding off numerical values.  
TZS 265, Textiles – Methods of testing the strength of yarns from packages – Part 1: Determination

3. Terms and definitions  
For the purpose of this Draft Tanzania Standard, the following definitions shall apply:  
3.1 cheese  
cylindrical package of yarn wound on a flangeless tube.  
 
3.2  filament  
fiber of an indefinite or extreme length such as found naturally in silk. Manufactured fibers are extruded 
into filaments that are converted into filament yarn, staple, or tow.  
3.3 runnage  
length of twine  or cord. per unit weight.  
 
3.4  strand  
ordered assemblage of textile fibers having a high ratio of length to diameter and normally used as a 
unit; includes slivers,  roving, single yarns, plie d yarns, cords, braids, ropes.  
 
4. Requirements  
 
4.1 General  
4.1.1  Materials  
The material used in the manufacture of twines shall be of high density continuous  monofilament 
polyethylene having a relative density of 0.95 to 0.96 and a minimum tenacity of 40 g/tex within the 
range of 0.15 to 0.20 nominal diameter of yarn .

4.1.2  Design and constructions   
The twines shall either be supplied in natural colour or as required by the buyer. The finished twines 
shall be flexible a nd consist of 3 strands , each being uniform and well laid and  free from defects in the 
yarn.  
 
4.2 Specific requirements  
4.2.1  The twines shall conform to the requirements given in Table 1. The twines shall have S twist 
unless otherwise agreed to between the manufacturer and buyer.  
 
4.2.2  Mass  
A tolerance of ±5 percent shall be allowed on the declared mass of any one package provided that the 
variation from the gross specified mass of any delivery to one code number does not exceed 5 percent.

 5. Packaging, p acking  and marking  
 
5.1 Pack aging and packing  
A number of hanks or cheeses  of twine as agreed by  the buyer  shall be placed one over the other and shall 
be wrapped with a layer of waterproof pack aging material. The pack shall be tied with twine of adequate 
strength and a suitable number of such pac ks shall be packed in a container of adequate strength whi ch 
is previously lined with one layer of waterproof packing paper .  
 
5.1 5.2 Marking   
The han k or che eses containing twines shall be marked  with the following information:  
a) Name of the material,  
b) Construction and runnage,  
c) Gross and net mass,  
d) Month and year of manufacture  and batch number , 
e) Number of pieces in a single package, and  
f) Indication of the source of manufacture.  
 
 
6 Sampling and criteria for conformity  
6.1 Lot  
The quantity of monofilament twines of the same run nage and constructi on details delivered to a buyer 
against one dispatch note shall constitute a lot.  
 
6.2 Conformity of  a lot to the requirements of this  standard shall be determined on the basis of test carried  
out on the  sample selected from it.  
 
6.3 The number of cheeses/packs to be selected at random from a lot shall be as given in Table 2 below :

 ANNEX A  
(Normative )  
METH OD FOR DETERMINATION OF RUNNAGE   
A-1 TEST SPECIMENS  
Remove 10  m length skeins from each of the hank or cheese constituting the sample under test.  
A-2 PROCEDURE  
Determine the mass of a skein removed f rom a hank or cheese to the near est gram. From the mass 
compute the runnage (m/kg).
