The Importance of RDSO Approval in Railway Abrasives

The Research Design and Standards Organisation (RDSO)

The RDSO is the technical advisor to the Railway Board of India. For any product to be used on the Indian Railways network, it must pass rigorous RDSO testing.

Why Rail Cutting is Different

Rail steel is exceptionally tough and often work-hardened from years of train traffic. Cutting an 80kg rail requires an abrasive wheel that can handle extreme friction, heat, and torque without warping or shattering.

Apidor's RDSO Certification

Apidor's 400mm rail cutting wheels have passed the RDSO's stringent performance and safety criteria. They are designed to operate on petrol-driven portable saws at peripheral speeds up to 100 m/s, delivering straight, fast cuts essential for minimizing track downtime.
