IS 7032 : Part 1 to 8 : 1986 : Physical methods of test for uncut Indian jute, Mesta and Bimli

0. FOREWORD

0.1 This Indian Standard ( Parts 1 to 8 ) ( First Revision ) was adopted by the Indian Standards Institution on 27 June 1986, after the draft finalized by the Physical Methods of Test Sectional Committee had been approved by the Textile Division Council.

0.2 This standard consisting of nine parts ( Parts 1 to 9) was published between 1973 and 1976 and covered methods of test for various characteristics of jute fibres. After the publication of IS : 271-1975 ·Grading of white, TOSS A and DAISE£ uncut Indian jute ( second revision), IS : 9846- 1981 Grading of uncut Indian MESTA, and IS: 11596-1986 Grading of uncut Indian BTMLI have been published. These standards have taken into consideration the characteristics such as strength, lustre, colour, density, fineness, root content and defects, etc, for grading of fibres. These grading standards prescribe the Hand and eye method for grading and allot scores for different characteristics. This standard ( Parts 1 to 8 ) has been revised to make it applicable to MESTA and BJMLI fibres also. The method for determination of brightness ( colour ) ( Part 9 ) has been withdrawn.

0.3 This standard is aimed at obtaining instrumental measures for characteristics of jute, MESTA and BIMLI fibres for the purpose of grading. To achieve this aim only those methods, which are simple and could be adopted by the graders with the minimum of efforts and where scoring could be possible, have been selected after survey of the work done by research institutions, the published literature and also keeping in view the type of instruments available with the industry.

0.4 In reporting the result of a test made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS : 2-1960*.
