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 ISO BIS BS BS EN - 129 STANDARDS 34 STANDARDS 17 STANDARDS 8 STANDARDS - 36 STANDARDS
