PART 1 DETERMINATION OF MASS PER UNIT AREA

1. SCOPE

1.1 This standard (Part 1) specifies amethod for the determination of the massper unit area of all natural fibre non-woven geo textile fabrics andcomposites for identification andpurposes and for use in technical datasheets.

1.2 The method is applicable to allnatural non-woven coir geo-textiles(NWCG)

2. PRINCIPLE

The mass per unit area is calculated byweighing small square or circularspecimens of known dimensions. Themass per unit area of an NWCG isdetermined by weighing test specimensof known dimensions cut from variouslocations over the full width of thelaboratory sample.

The measured weight is then used tocalculate the mass per unit area of thespecimen, and averaged to obtain themean mass per unit area of thelaboratory sample.

3. SPECIMENS

The specimens shall be cut in such a waythat they are representative of thematerial to be tested.

Cut not less then ten specimens and tonominal size of 100cm², unless thestructure of the geotextile is such that a100 cm² specimen is not representative,in which case a larger specimen sizeshall be used.

4. PROCEDURE

Determine the area of each specimen toan accuracy of 0.5 percent. Weigh eachspecimen to an accuracy of 0.1 percent.

5. EXPRESSION OF RESULTS

A constant rate of extension (CRE) or aconstant-rate-of traverse (CRT) tensiletesting machine as specified in IS1969:1985 shall be used.

5.2 Jaws which are sufficiently wide tohold the entire width of the specimenand with appropriate means to limitslippage or damage.

5.2.1 Compressive grips will be used formost materials. For materials where theuse of compressive grips gives rise toexcessive jaw breaks or slippage captiongrips may be used.

5.2.2. When caption grips are used, thereason for their use and the separationbetween the tests should be kept to aminimum. The use of caption shall bespecified in the report.

NOTE – It is stressed that it isessential to choose jaw faces thatlimits the slippage of the geo-textilethat may occur especially for strongergeo-textiles.

6.3.4 When both the wet maximum loadand the dry maximum load are required,cut each test specimen at least twice therequired length. Number each testspecimen and then cut cross wise intotwo parts, one for determining the drymaximum load, and the other fordetermining the wet maximum load ,each portion shall bear the specimennumber. In this manner each pairedbreak is performed on test specimenscontaining the same threads.

NOTE – For geo-textiles which shrinkexcessively when wet, the tensilestrength is determined from themaximum load in wet conditions theinitial width before wetting.

7. CONDITIONING ATMOSPHERE

7.1 The test specimen shall beconditioned and the test conducted in the

standard atmosphere for testing textilesas prescribed in IS 6359:1971

NOTES

1. The test specimen may beconsidered to have beenconditioned when the change inmass of the test specimen in anytwo successive weighing made atintervals of not less than 2 h doesnot exceed 0.25 percent of theoriginal mass of the testspecimen.

2. Conditioning and or testing at aspecified relative humidity maybe omitted if it can be shown thatthe results are not affected.

7.2 Test specimen to be tested in the wetcondition shall be immersed in water,maintained at a temperature of 27 ±2º C.The time of immersion shall besufficient to wet out the test specimensthoroughly, as indicated by nosignificant change in maximum load orstain following a longer period ofimmersion, and at least 24 hours. Toobtain through wetting it may benecessary to add not more than 0.05percent of a nonionic natural wettingagent (see 5.5) to the water.

8. PROCEDURE

8.1 Setting up of machine

8.1.1 Adjust the distance between thejaws at the start of the test to give alength of 100 ±3mm except for geo-gridsand for geo-textiles when using capstangrips. Select the force range of thetesting machine such that the breakoccurs between 30 percent and 90percent of the full scale force. Set themachine to a rate of strain or rate of

traverse as given in 4.1. Test theconditioned specimens in the atmospherespecified in 7.

8.1.2. For wet test specimen perform thetest within 3 minutes after removal fromthe water.

8.2 Insertion of Test Specimen in Jaws

8.2.1. Mount the test specimen centrallyin the jaws. Take care that the specimenlength in the machine direction and crossdirection tests, respectively, is parallel toy=the direction of application of force.Where appropriate do this by having thetwo lines, which were previously drawn100 mm apart across the with of the testspecimen positioned as close as possibleadjacent to the inside edges of the upperand lower jaws.

8.3 Installation of the Tensile testingMachine on the Extensometer

Place the reference points on the sample.Ensure that there will be no slippage ofthe points during the mounting of thespecimens or during testing.

8.4 Measurement of Tensile Properties

8.4.1 Start the tensile testing machineand continue running the test until thespecimen ruptures. Stop the machine andreset to the initial gauge position. Recordand report the maximum load to anaccuracy of 00.2 percent of the full scaleand strain to the first decimal place.

8.4.2 The decision to discard a breakshall be based on observation of thespecimen during the test upon theprovision of 5.4. In the absence of othercriteria for rejecting a jaw break, anybreak occurring with in 5 mm of the

jaws which results in a value below 50percent of the average of all other breaksshall be discarded. No other break shallbe discarded unless the test is known tobe faulty.

NOTES

1. It is difficult to determine theprecise reason why certainspecimens break near the edge ofthe jaws. If a jaws break iscaused by damage to the testspecimen by the jaws, due torandomly distributed weak place,it is a legitimate result. In somecases, it ma also be caused by aconcentration of the stress in thearea adjacent to the jaws width asthe load is applied. In thesecases, a break near the edge ofthe jaws is inevitable and shouldbe accepted as a characteristic ofthe particular method of test.

2. Special procedures are requiredfor the preparation of testspecimen made from specificmaterials (glass fiber, carbon,Composite geo-textiles, etc.) tominimize damage in the jaws. Ifa test specimen slips in the jawsor if more than one quarter of thespecimens break at a point within5 mm of the edge of the jaw, then(a) the jaws may be padded (b)the test specimen may be coatedunder the jaw face area; or (C)the jaw face may be modified. Ifany of the modification listedabove are used, state the methodof modification in the test report.

8.5 measurement of Strain

Measure the increase in gauge length ofthe test specimen at any stated load bymeans of a suitable recording device.
