IS 14710:2020 Part 1 is the Indian Standard (BIS) for geosynthetics - geogrids - general characteristics and methods of test. This standard outlines the general characteristics and standardized laboratory test methods for evaluating geogrids used in geotechnical applications. It provides procedures for determining key performance indicators such as wide-width tensile strength, junction strength, installation damage resistance, and creep. This code is essential for quality assurance, product comparison, and providing input data for geotechnical design.
Specifies general characteristics, terminology, sampling and methods of test for geogrids.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
