FOREWORD
This Indian Standard (Third Revision) wasadopted bythe Bureau of Indian Standards, after thedrafi finalizedby the
Natural andSyntheticFragrance Materials SectionalCommitteehadbeenapproved bythePetroleum, CoalandRelated
ProductsDivision Council.
Thisstandardwasfirstissued in1954andsubsequentlyrevised in 1973and 1998.TheCommittee notedthatevenafter
removal of one or more of its constituents, the product was found to be still conforming to the specification which
necessitated the first revision. In the second revision, only asingle grade of gum spirit of turpentine, with minimum
limitsforthemajor constituents, that is,alpha-pinene andcar-3-ene,wasspecified toensure coverage ofthewholeoil
tothisspecification. Inthis revision, physico-chemical requirements havebeenprescribed at20°Cinaddition to27°C.
Besides, requirement for acid value hasbeen madestringent anddistillation range has been modified.
Thewholeoilofturpentine finds applications inthemanufacture ofpharmaceuticals, perfumery andother chemicals.
Itsuse inpaint industry isbeing taken qpbyturpentine fromwhich one or more constituents are removed. The latter
