WET TRANSVERSE STRENGTH TESTING MACHINE IS 13801-ANNEX F

WET TRANSVERSE STRENGTH TESTING MACHINE (For Cement Concrete Tiles / Flooring Tiles)

TEST PRINCIPLE

The test specimen (tile), conditioned under water immersion, is subjected to a gradually applied central load while supported at two ends. The load at fracture is recorded and used to calculate the transverse strength.

PRODUCT DESCRIPTION

The Wet Transverse Strength Testing Machine is designed for determining the flexural (transverse) strength of cement concrete tiles under wet conditions, in accordance with:

1. IS 13801 (Annex F) – Chequered Cement Concrete Tiles
2. IS 1237 (Annex F) – Cement Concrete Flooring Tiles

The machine operates on the three-point bending principle, ensuring accurate and repeatable determination of tile strength under simulated service conditions.

SALIENT FEATURES

1. Fully compliant with IS standards
2. Uniform and controlled loading rate
3. Self-aligning fixture for accurate results
4. Adjustable span for different tile sizes
5. Robust and low-maintenance design
6. Suitable for quality control and R&D applications
