FOREWORD
ThisIndian Standard(FirstRevision)wasadoptedbythe BureauofIndian Standards,afterthe draft finalized
bythe Tobaccoand Tobacco Products Sectional Committeehad beenapproved by the Food andAgriculture
Division Council.
Withthe growthofindigenousmanufactureofcigarettes,the use offilters inthe cigarettesison the increase.
It is hoped that this standard would serve the need to regulate the quality of filters that are indigenously
produced and thereby enable control on quality ofcigarettes that are manufactured.
This standard was originally published in 1983. In this first revision, its provisions are updated to include
advances in technology in this area during the last two decades. In the formulation ofthis standard due
weightage has been given to international co-ordination among the standards and practices prevailing in
different countries in addition to relating it to the practices in this field in the country. The figures ofthe
apparatus used for determining various characteristics have also been incorporated in this standard.
Forthe purposeofdecidingwhetheraparticularrequirementofthis standard iscomplied with, the final value,
observed or calculated, expressingthe results ofa test or analysis, shall be rounded offin accordance with
IS2 : 1960 'Rulesfor roundingoffnumerical values(revised}'. The numberofsignificant placesretained in
the rounded offvalue should be the same as that ofthe specified value in this standard.
