TEST METHODS FOR GEOTECH PRODUCTS K.VENKATARAYAN BOMBAY TEXTILE RESEARCH ASSOCIATION
WHY TESTING • PRODUCT QUALITY • COMPLIANCE TO REGULATORY REQUIREMENTS • DESIGN AND DEVELOPMENT • SPECIAL CONSIDERATIONS
SPECIFICATIONS • FUNCTIONAL PARAMETERS • NON FUNCTIONAL PARAMETERS
FUNCTIONAL PARAMETERS • PERFORMANCE FOR INTENDED USE • LONG USEFUL LIFE • MINIMUM ACCIDENT HAZARDS • PROTECTION OF LIFE OR PROPERTY • INTERCHANGEABILITY IN THE FIELDS • COMPETITIVE SALES ADVANTAGE
NON FUNCTIONAL PARAMETERS • HELP TO DESIGN THE PRODUCT AND PROCESS • REGULATORY REQUIREMENTS
GEOTECH • PRODUCT USED – GEOSYNTHETICS • GEOCOMPOSITE • GEOFOAM • GEOGRID • GEOMEMBRANE • GEONET • GEOTEXTILE
FUNCTIONS • SEPARATION • FILTRATION • DRAINAGE • REINFORCEMENT • PROTECTION
GEOTECH PRODUCTS TESTS • SIMULATING CLOSE TO USER REQUIREMENTS • SPEEDY AVAILABILITY OF RESULTS • EASE OF TESTING AND AVAILABILITY OF EQUIPMENTS • COST EFFECTIVE
TEST METHODS FOR GEOSYNTHETICS • ASTM - 129 STANDARDS • ISO - 34 STANDARDS • BIS - 17 STANDARDS • BS - 8 STANDARDS • BS EN - 36 STANDARDS
BIS TEST METHODS • IS 13321-1 Glossary of terms for geosynthetics • IS 13325 Wide width tensile strength of geogrid • IS 13326-1 Direct shear test for geosynthetics • IS 14986 Guide lines for jute geotextile for Erosion control • IS 13162-2 Deterioration of geotextile from UV exposure • IS 13162-3 Thickness • IS 13162-4 Puncture resistance by Falling cone • IS 13162-5 Wide width tensile strength of geotextile • IS 14293 Trapezoid tear strength of geotextile • IS 14294 Apparent Opening Size by dry sieving
BIS TEST METHODS • IS 14324 Water permeability • IS 14706 Sampling & preparation of test specimen • IS 14714 Abrasion resistance • IS 14716 Mass per unit area • IS 14739 Creep rupture behaviour of geotextile • IS 15060 Seam strength of geotextile by wide width strip
TX 30 Approved the following Draft Standardsbased on ISO standards • Determination of filtration behaviour of geotextile under turbulent water flow condition • Wide width tensile strength of geotextile • Seam strength by wide width strip tensile method • Open weave coir bhoovastra • Determination of compressive creep properties • Short term creep compression behaviour • Determination of water permeability normal to the plane without load • Determination of water permeability normal to the plane under load • Determination of gas flow through GCL
BOMBAY TEXTILE RESEARCH ASSOCIATION - BTRA • CENTRE OF EXCELLENCE FOR GEOTECH • ACCREDITED BY NABL FOR ISO 17025-2005 • ONLY LABORATORY IN INDIA ACCREDITED FOR GAI-LAP BY GSI USA. • ONE STOP SHOP FOR GEOSYNTHETICS TESTS
CONCLUSION • TEST METHODS ARE A MEANS TO UNDERSTAND THE PRODUCT • TEST RESULTS GIVE A TRUE PICTURE OF THE PRODUCT • TEST RESULTS ARE DEPENDABLE WHEN CONDUCTED EXACTLY AS PER THE STANDARD TEST METHODS • ACCREDITATION TO ISO 17025 -2005 ENSURES THE LABOARTORY’S COMPETENCE IN GIVING CONSISTENTLY ACCURATE RESULTS
