 Annex  A 
(normative ) 
Determination of dimensions of shirts  
A.1 Principle  
Lay a piece of a shirt on a flat table removing any curls and without stretching, take the measurements from 
one end to the other using a steel rule. Repeat the procedure for other specimens in the laboratory sample . 
A.2 Apparatus  
A.2.1  Flat table  
A.2.2  Steel rule, accuracy of at least 1 mm  
A.2.3  Calculator  
A.3 Sampling  
From a laboratory sample, take one shirt and subject it to conditioning prior to testing.  
A.4 Conditioning  
Condition th e specimen in accordance with RS  ISO 139.  
A.5 Procedure  
Take each shirt constituting the test sample. Lay it flat on a table. Remove by hand all creases and wrinkles 
without distorting it. M easure correct ly to the nearest 0.5 cm the dimensions given in Table 2 or Table 3.  
Repeat the procedure for any other specimen that may be required in the laboratory sample.  
A.6 Calculation and expression of  results  
Take the average of the individual measureme nts and double the result to obtain the dimensions
