12. 12  GEO-TEXTILES HAVE SPECIFIC CONSTRUCTIONS AND WORK IN SPECIFIC SOIL CONDITIONS AND END USES, THE TEST METHODS USED FOR ORDINARY TEXTILES ARE NOT APPLICABLE TO THEM.  THE DEGREE OF BENEFITS OFFERED BY GEO- TEXTILE MATERIALS TO SOIL FABRIC AGGREGATE SYSTEM DEPENDS TO A LARGE EXTENT ON THE PROPERTIES OF THE SOIL AS WELL AS THE FABRIC USED  KEEPING THIS IN VIEW, BIS HAS PUBLISHED INDIAN STANDARDS ON GEO-SYNTHETICS

13. 13  IS 13321(PT 1): 1992 GLOSSARY OF TERMS FOR GEO- SYNTHETICS, PART I TERMS USED IN MATERIALS AND PROPERTIES THIS STANDARD IS COMPILATION OF THE TERMS RELATING TO MATERIAL AND PROPERTIES, LIKE ABSORPTION, APPARENT OPENING SIZE, BIO- DEGRADABILITY, BONDING, BREAKING LOAD, TOUGHNESS, CHEMICALLY BONDED NON-WOVEN FABRIC, CLOGGING, COATED FABRICS, COMPRESSED THICKNESS, DISCONTINUOUS FIBRE, ELASTIC LIMIT, EXTRUDED MESH, EXTRUDER FABRIC, COMPOSITE, FABRIC KNIT, FABRIC NON-WOVEN, BREAKING LOAD, GEO-CELL, GEO- COMPOSITE, GEO-GRID, GEO-MEMBRANE, INDEX TEST, INITIAL TENSILE MODULUS, OFFSET, TENSILE MODULUS, STIFFNESS.

14. 14  IS 13326(PT 1): 1992 - METHOD OF TEST FOR THE EVALUATION OF INTERFACE FRICTION BETWEEN GEO- SYNTHETICS AND SOIL PART I MODIFIED DIRECT SHEAR TECHNIQUE THIS STANDARD PROVIDES DETAILS ON TEST METHODS FOR DETERMINATION OF COEFFICIENT OF INTERFACE FRICTION BETWEEN A GIVEN SOIL (INCLUDING AGGREGATE AND BALLAST) AND A GEO-SYNTHETIC USED FOR REINFORCEMENT PURPOSES. THIS METHOD IS ALSO APPLICABLE FOR ASSESSING THE FRICTION BETWEEN A GEO-MEMBRANE AND THE NATURAL OR COMPACTED SOIL IN ORDER TO ANALYZE THE STABILITY OF THE CANAL/RESERVOIR LINING.

15. 15  IS 14986:2001 GUIDELINES FOR APPLICATION OF JUTE GEO-TEXTILE FOR RAIN WATER EROSION CONTROL IN ROAD AND RAILWAY EMBANKMENT AND HILL SLOPES THIS STANDARD HAS BEEN PREPARED BASED ON THE DATA PROVIDED BY THE INDIGENOUS MANUFACTURERS AND TAKING INTO CONSIDERATION THE PRACTICE PREVALENT IN INDIA. THE SPECIFIC REQUIREMENTS, SELECTION, INSTALLATION METHOD, MONITORING AND REQUIREMENT OF PACKING HAVE BEEN COVERED IN THIS STANDARD

16. 16  IS 13162(PT 2):1991 GEO-TEXTILES - METHODS OF TEST PART 2: DETERMINATION OF RESISTANCE TO EXPOSURE OF ULTRA-VIOLET LIGHT AND WATER (XENON ARC TYPE) THIS STANDARD PRESCRIBES A METHOD FOR THE DETERMINATION OF RESISTANCE OF GEO- TEXTILES TO THE EXPOSURE OF ULTRAVIOLET LIGHT AND WATER. THE LIGHT AND WATER EXPOSURE APPARATUS EMPLOYS A XENON-ARC LIGHT SOURCE.

17. 17  Geo-textiles are manufactured using a variety of processes and formulations of polymers and each geo- textile varies in its sensitivity to ultraviolet radiation. Ultraviolet radiation from the sun varies with duration of exposure, angle of inclination of the sun, atmospheric conditions, topography, and geography. The Xenon-arc test cannot simulate all these variables, so it is not likely that Xenon-arc test results will relate directly to sunlight exposure test results for a specific fabric at a given site.  The method prescribed is suitable for comparative evaluation of geotextiles and is not recommended for acceptance testing of commercial shipments since information on inter-laboratory precision is incomplete.

18. 18  IS 13162 (PT 3): 1992 GEO-TEXTILES - METHODS OF TEST PART 3: DETERMINATION OF THICKNESS AT SPECIFIED PRESSURE THIS STANDARD PRESCRIBES TWO METHODS FOR DETERMINATION OF THE THICKNESS OF GEO-TEXTILES AT SPECIFIED PRESSURES AND DEFINES AT WHICH PRESSURE THE NOMINAL THICKNESS IS DETERMINED. METHOD A ( LOADING EACH SET OF SPECIMENS ) SHALL BE USED WHEN USING AN APPARATUS THE CONSTRUCTION OF WHICH CAUSES A HIGH DEGREE OF TIME AND/OR LABOUR WHEN CHANGING THE PRESSURE, OTHERWISE METHOD B (INCREMENTAL LOADING OF INDIVIDUAL SPECIMENS ) SHALL BE USED. THE METHOD IS APPLICABLE TO ALL TYPES OF GEO-TEXTILES.

19. 19  Since the geotextiles are compressible, the thickness measure will depend upon the pressure applied. For this reason it may be desirable to measure thickness at a series of pressures and to study the general relationship between thickness and pressure.

20. 20  IS 13162 (PT 4): 1992 GEO-TEXTILES - METHODS OF TEST PART 4: DETERMINATION OF PUNCTURE RESISTANCE BY FALLING CONE METHOD Geotextiles used as separator and filter in earth constructions are normally subjected to dynamic impact. During the installation process, crushed rock or boulders are dropped onto a fabric supported by weak, water-saturated soil which may penetrate and thus damage the geotextile. It is, therefore, desirable that the geotextiles should resist the sudden impact and penetration of such particles.

21. 21 THIS STANDARD PRESCRIBES A METHOD FOR DETERMINATION OF THE SIZE OF THE HOLE MADE BY DROPPING A STANDARD BRASS CONE ONTO A GEO-TEXTILE, SUPPORTED BY WATER, AND TO PROVIDE AN INDICATION OF THE ABILITY OF THAT FABRIC TO RESIST A SUDDEN IMPACT. THIS STANDARD PRESCRIBES A METHOD FOR DETERMINATION OF THE SIZE OF THE HOLE MADE BY DROPPING A STANDARD BRASS CONE ONTO A GEO-TEXTILE, SUPPORTED BY WATER, AND TO PROVIDE AN INDICATION OF THE ABILITY OF THAT FABRIC TO RESIST A SUDDEN IMPACT.

22. 22  IS 13162 (PT 5): 1991 GEO-TEXTILES - METHODS OF TEST PART 5: DETERMINATION OF TENSILE PROPERTIES USING A WIDE WIDTH STRIP THIS STANDARD PRESCRIBES AN INDEX TEST METHOD FOR DETERMINATION OF THE TENSILE PROPERTIES OF GEO-TEXTILES AND RELATED PRODUCTS USING A WIDE WIDTH STRIP. THE METHOD IS APPLICABLE TO MOST GEO-TEXTILES INCLUDING WOVEN FABRICS, NON-WOVENS, LAYERED FABRICS, KNITTED FABRICS AND FELTS. THE METHOD IS APPLICABLE TO GEO-GRIDS BUT THE SPECIMEN DIMENSIONS MAY NEED TO BE ALTERED. THIS METHOD COVERS THE MEASUREMENT OF LOAD ELONGATION CHARACTERISTICS AND INCLUDES PROCEDURES FOR CALCULATION OF SECANT STIFFNESS, MAXIMUM-LOAD PER UNIT WIDTH, STRAIN AT MAXIMUM LOAD AND EQUIVALENT STRAIN AT MAXIMUM LOAD. PROCEDURES FOR MEASURING THE TENSILE PROPERTIES OF BOTH CONDITIONED AND WET SPECIMENS ARE INCLUDED. THE MEASURING DEVICE CAN BE EITHER MECHANICAL, OPTICAL OR INFRA-RED.

23. 23 The basic distinction between this method and other methods for measuring tensile properties of fabrics, is the width of the specimen. This width by contrast is greater than the length of the specimen. Some geotextiles have a tendency to contract ( neck down ) under load in the gauge length area. The width of the specimen specified in this method reduces the contraction effect of those fabrics and provides a closer relationship to expected fabric behaviour in the field and a standard comparision of geotextiles.
