This Draft Tanzania Standard is being deve loped by Station ery and Paper  Products Technical 
Committee under supervision of the Chemical Division Standards Committee and it is in 
accordance with the procedures of the Bureau.  
 
This Draft Tanzania Standard is the first edition of specification for  papers used for printing maps  
and architectural drawings.  It specifies requirements for materials, the permanence of the paper  
and dimension .  
 
Maps, architectural  drawings and plans  are import ant reference document s and need  to be stored  
for many years. Information needs  to be printed on paper  that can hold the test of time in terms of 
ageing. Per sistence  of the paper to keep  its physical and chemical properties for a long durati on 
is of great signifi cance.  
 
This draft Tanzania Standard has been prepared with assistance draw n from the following 
documents:  
 
 
IS 12765:  Printing  paper, Map - Specification , published by India Bureau of Standards.   
 
KS 2790: Paper used for maps and a rchitectural drawings - Specification , published by 
Kenya Bureau of Standards  
 
ISO 9706 : Informatio n and documentation - Paper for documents - Requirements for 
permanence , Published by International Standards Organization.   
 
 
 
 
For the purpose of deciding whether a particular requirement of this Tanzania Standard is 
complied with, the final value observ ed or calculated, expressing the result of a test or an alysis, 
shall be rounded off in acc ordance with TZS 4 (see clause 2) .
