FOREWORD

This Indian Standard (Part 1) (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draftfinalized by the Cordage Sectional Committee had been approved by the Textile Division Council.

This standard was originally published in 1960 and subsequently revised in 1970, 1982 and 1992. In this revisionopportunity has been availed to align it with corresponding International Standard, 1S0 1181 : 1990 ‘Ropes —Manila and sisal — Specification’. The present revision has been made in the light of the experience gained andincorporate the following major changes:

a) Scope has been modified;b) Number of yam per strand has been incorporated in Tables 1,2 and 3;c) Tolerance on diameter has been provided; andd) Quantity of rot proofing agent has been specified.

The composition of the Committee responsible for formulation of this standard is given in Annex 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 withIS 2:1960 ‘Rules for rounding off numerical values (rcwise~’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

1 SCOPE

This standard (Part 1) prescribes the requirements ofthe following types of untarred electro-mechanicallymade sisal ropes:

a) Hawser-laid (three-strand) sisal ropes ofdiameter 6 to 128 mm and with a linear densityfrom 29 to 11380 ktex;

b) Shroud-laid (four-strand) sisal ropes of diameter12 to 96 mm and with a linear density from 105to 6400 ktex; and

c) Cable-laid (nine- strand) sisal ropes of diameter40 to 144 mm and with a linear density from1030 to 13105 ktex.

2 REFERENCES

The tests shall be carried out under prevailingatmospheric conditions. In all cases of dispute,however, tests shall be carried out on samples whichhave been conditioned for 24 h in an atmosphere at65 * 2 percent relative humidity and 27 + 2°Ctemperature (see IS 6359). Where practicable, tests shallbe made in the standard atmosphere, otherwise, theyshall be made as quickly as possible not exceeding15 min of removal of the test pieces from conditioningatmosphere.

5 MANUFACTURE

5.1 Sisal Fibre

The fibre shall be well hackled and of quality, finenessand colour necessary to produce ropes having thecharacteristics required and specified in the respectivetables (see Table 1 to 3).

5.2 Yarn

The evenly spun yarn processed on hard fibreprocessing plant shall be used for manufacture of theropes. Hand-hackled or hand-spun yam shall not beused.

To comply with the minimum number of yarns specifiedin this standard, yarn of 4.6 ktex shall be used.

5.3 Strand

The strand of ropes shall be well formed and free fromgrooves and sunken yarns, and each strand shall containan equal number of yams. The strand shall have S-lay.

5.4 Ropes

The ropes shall be well laid and free from defects andeach coil shall be continuous throughout its length andshall not contain loose ends, splices or joints in thestrands or in the rope. The number of strands in therope and the lay of rope, unless otherwise specified,shall be as unde~

NOTE — Shroud-laid sisal rope shatl contain awe of appropriate

diameter.

5.4.1 The angle of lay for all types of ropes shall be37°.

5.5 Lubrication

Weighing or loading materials shall not be used. Forthe purpose of dressing the tlbre or for the preservationof the rope, a lubricant shall be added preferablypetroleum products. The quantity of dressing appliedto the fibre shall be neither less than 10 percent nor

1

....-.

IS 1321 ( Part 1 ) :2003

more than 15 percent calculated on the mass of thefinished rope when determined by extraction withpetroleum ether or other suitable solvent.

5.6 Rot-Proofing Treatment

If so ordered, ropes shall be rot-proofed by theapplication of suitable rot-proofing agent in appropriatequantity to protect the rope from mildew, fungus andbacterial effect as agreed to between the buyer and theseller. The rot-proofing agent may be applied in thefibre at the dressing stage for uniform penetration inthe rope. Ropes, which have been so treated shallotherwise comply, in all rqspects, with the requirementsof this standard. In case zinc or copper napthenate isused, the zinc content shall be 0.8 percent to 1.2percentand copper content shall be 0.5 percent to 1.2 percentrespectively and estimation of zinc and copper shall bedone in accordance with IS 3522 (Part 1).

6 REQUIREMENTS

6.1 Mass of the Coil

The net mass of the coil shall be determined inaccordance with IS 7071 (Parts 1 to 3). This mass shallnot vary more than the tolerance limits given belowfrom the calculated value of net mass obtained bymultiplying nominal linear density of the coil withlength of rope in the coil:

Reference No. of Rope Tolerance, Percent

IS 1321( Part 1 ) :2003

1986 and rules and regulations made thereunder. Thedetails of the conditions under which a licence for theuse of the Standard Mark may be granted tomanufacturers or producers may be obtained from theBureau of Indian Standards.

11 SAMPLING AND CRITERIA FORCONFORMITY

11.1 Lot

The quantity of coils of rope of the same linear density,type and dimensions, manufactured under similarconditions and delivered to a buyer against one despatchnote shall constitute a lot.

11.2 The conformity of the lot shall be determined onthe basis of the tests carried out on the samples selectedfrom it.

11.3 Sampling shall be as representative as possible ofthe lot. Draw the samples at random at the rate shownby the following formula:

S = @4N

where

S is the number of coils in the sample, andN is the size of the lot expressed, as number of

coils.

When S as, calculated is not a whole number, round offthe value obtained to give a whole number inaccordance with the requirements of IS 2 : 1960. Incase where S is less than one drawn a sample coil.

11.4 For evaluating the length, linear density, breakingstrength and pitch, the number of coils selectedaccording to 11.3, shall constitute the test sample.

11.4.1 For evaluating the net mass of the lot, all thecoils into the lot shall constitute the test sample.

11.5 Criteria for Conformity

The lot shall be declared conforming to this standard iffollowing conditions are satisfied:

a) Length of each coil satisfies the specifieddeclared length;

b) All the individual test samples tested for breakingstrength satisfi the specified breaking strength.However, in case of failure of the test specimendrawn from a coil, another specimen shall beretested from the same coil and the same shallsatisfi the specified requirement; and

c) Average values of the test results of the lot inrespect of other characteristics conform to thespecified requirements.
