Foreword  
 
This Draft Tanzania Standard  specifies requirements to be complied with by manufacturers producing  
woven and warp knitted quilts, duvet fabrics and duvet covers.  
 
In the preparation of this finalized Draft Tanzania Standard  assistance was derived from;   
 
ASTM International Standard D4769 − 12; Standards specification for woven and knitted 
comforter fabrics  
 
In reporting the result of a test made in accordance with this Draft Tanzania Standard , if the final value 
observed or calculated is to be rounded off, it shall be done in accordance with TZ S 4. (see clause 2).  
 
 
 
 
 
 
 
 
   
  
1. SCOPE  
 
1.1 This Draft Tanzania Standard  specification covers woven and warp knitted quilt fabrics, composed of 
any suitable  textile fibre, or fibre blends.  
 
1.2 The requirements apply to the length and width directions for those properties where fabric direction is 
pertinent.

7. SAMPLING  
 
7.1 Lots  
 
7.1.1 The quantity of quilt products of the same type and quality delivered to one buyer against one 
dispatch note shall constitute a lot.  
7.1.2 The conformity of the lot to the requirements of this Draft Tanzania Standard  shall be determined on 
the basis of tests carried out on the samples selected from the lot .  
7.1.3 The number of pieces to be selected at random from a lot shall be in accordance with the second 
column of Table 2. These pieces shall be selected fr om at least 10 % of the bales, an equal number of 
pieces, as far as possible, being at random from each bale.

6.2. Criteria for conformity  
 
a) From the observed values of breaking load tests in respect of each piece in the test sample, the 
average breaking load is calculated.  
From all such average values, the grand average ( ) and the average range R1 is calculated and 
the value of the expressio n – 0.4R 1 is found to be greater than or equal to the specified value.  
 
b) From the observed values of shrinkage the average  and the range R are calculated and the 
value of the expression  +0.4R  is less than or equal to the specified value.  
 
 NOTES – Average ( ) is the value obtained by dividing the sum of observed values by the number of 
tests.   Range ( R) is the difference between the maximum and the minimum in a set of observed 
values.
