Title: Standard Specifications & Code of Practice for Road Bridges - Section IX: Elastomeric Bearings.
Comprehensive Indian Roads Congress standard for design, raw polymer properties, steel laminate thickness, permissible compressive stresses, and shear strain limits.
Title: Methods of Test for Vulcanized Rubber - Chemical & Physical Testing.
Indian Standard defining mandatory laboratory testing procedures for elastomer compounding, chemical ash content, polymer identification, and cure parameters.
Title: Rubber, Vulcanized - Tensile Stress-Strain Properties Determination.
International test method governing dumbbell test pieces, tensile strength (≥ 17 MPa), elongation at break (≥ 400%), and modulus at 100% and 300% elongation.
Title: Rubber, Vulcanized - Resistance to Ozone Cracking (Static & Dynamic).
Prescribes the ozone chamber test parameters ensuring elastomeric bearings exhibit zero micro-cracking when exposed to high ozone concentrations over 72 hours under static strain.
Title: Rubber, Vulcanized - Accelerated Ageing & Heat Resistance Tests.
Standardizes hot-air circulating oven exposure at 70°C / 100°C to evaluate polymer degradation resistance, ensuring long-term 50+ year service life in bridges.
Title: Rubber, Vulcanized - Determination of Tear Strength (Trouser, Angle & Crescent).
Governs tear resistance limits to prevent crack propagation under extreme bridge deck live load rotations and lateral seismic shears.
Title: Vulcanized Rubbers - Compression Set at Normal & High Temperatures.
Tests permanent deformation of rubber under continuous compressive strain (25% deflection for 24h at 70°C) ensuring high elastic recovery (≤ 35% compression set).
Title: Rubber, Vulcanized - Determination of Hardness (10 to 100 IRHD).
International standard defining IRHD micro and macro indentation hardness measurements for bridge bearing elastomeric compounds (specified 60 ± 5 IRHD).
