ONE-INCH SIZES 



The series of standard 1-inch sizes is illustrated 

 by the chart shown in Figure 1. Each size of this 

 series has a fixed variation of 1 inch (or 2V2 centi- 

 meters) in length. 



REQUIREMENTS 



When tobacco is represented to be of any one of the 

 standard sizes covered by the chart shown in Figure 

 1, 90 per cent of the leaves of the lot or package must 

 fall within the range of such size. For example : If a 

 lot or package of tobacco is represented to be of U. S. 

 size 17%, then 90 per cent of the leaves of such lot 

 or package must be between 17 and 18 inches (or 42.5 

 and 45 centimeters) in length. 



APPLICATION 



The sizes of the 1-inch series are used to state the 

 length factor in certain grades of some types in which 

 the length of leaf is of prime importance. These sizes 

 are particularly applicable to the grades of shade- 

 grown wrappers. They are not ordinarly used, on 

 account of the extreme accuracy required, except on 

 lots of tobbacco that have been leaf sized on sizing 

 boards or in sizing boxes laid off according to the 

 range of sizes shown in Figure 1.
