Testing Facilities

A fully-equipped in-house laboratory for elastomer, metallurgical, bearing-load and expansion-joint testing as per IRC, IS and ASTM standards.

Elastomer / polymer testing

• Universal tensile strength testing
• Compression set apparatus & shore hardness testers
• Specific gravity, ash content & viscometer (adhesive viscosity)
• Polymer content & identification – ASTM D-297, IS 3400 Part XXII
• Adhesion strength of elastomer to steel plate – IS 3400 Part XIV (A)

Bearing load testing

• Fixtures for load-deflection, bond & compression load-deflection tests with electromechanical load machines
• Calibrated measuring tape, Vernier caliper & parallelism meter
• Ageing oven/chamber; laboratory mixing mill & testing hydraulic press with temperature, timer & pressure control

Expansion joint testing – IRC:SP:69-2011

• Cyclic motion, ponding, debris-expelling, pull-out & opening-movement vibration tests (Para 8.3.2.1 to 8.3.2.5)
• Fatigue & abrasion-resistance testing
• Compressive/tensile, bend, impact, hardness, chemical, ultrasonic & liquid-penetration testing

Fabrication, welding & coating

• Oxy-acetylene profile cutting, radial drilling, shaper & welding rectifiers/manipulators
• Weld-size, throat-thickness & edge-preparation gauges
• Surface preparation, shot/grit blasting, metalizing & hot-dip galvanization (via valid MOU)
• Elcometer / Dry Film Thickness gauge
