This standard wasfirst published in 1950andrevised in 1969, 1975and 1987. The original standard covered WHITE (Cm-chorus Capsdaris) and TOSSA (Con4zorus Olitorius) jute and classified them into 4 grades, namely, tops, middles, bottoms andcross(X). The first revision ofthe standard included L?AZSEE(Corchorus Olirorius)jute inaddition toWHITE and TOSSA. The WHITE jute wasclassified into 8grades, namely, W1, W2, W3, W4, W5, W6, W7 and W8; and TOSSA and DAISEEjute into 8grades, namely, TDl, TD2, TD3, TD4,TD5,TD6,TD7 and TD8. A scoring system was also introduced to grade the fibreson the basis of the diffe~entcharacteristics. Inthesecondrevision,thescoresfordifferent characteristics weremodified tofacilitate effective, implementation ofthe standard. In thethird revision, ‘Defects’-parameter inrespect of grades W2 toW5 for WHITE jute and TD2 toTD5 for TOSSA and DAZSEEwere modified. The present revision of this standard hasbeen taken up to incorporate the modified scores for different characteristics and maximum root content for better implementation bythejute growers andtraders. The composition ofthe Committee responsible forthe formulation ofthis standard isgiven inAnnex B. For the purpose of deciding whether a particular requirement of this standard is complied with the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: 1960 ‘Rulesforrounding off numerical values (revised)’. The number of significant places retained inthe rounded off value should bethe sameasthatof the specified value inthis standard.
