Direct shear machine calibration.

Our Services

Ensuring Accurate Shear Strength Measurement for Geotechnical Testing

Direct shear machine calibration is carried out to verify the accuracy of applied normal load, shear load, and displacement measurements used in determining the shear strength parameters of soil and granular materials. Proper calibration is essential to ensure reliable values of cohesion (c) and angle of internal friction (φ), which are critical inputs for safe foundation and slope design.

Why Direct shear machineMatters.

Ensures Accuracy of Shear Strength Parameters

Calibration confirms that applied loads and measured displacements are accurate, preventing errors in evaluating soil shear strength.

Maintains Compliance With Quality and Audit Requirements

Regular calibration supports compliance with NABL, ISO/IEC 17025, IS standards, and internal quality systems of geotechnical laboratories.

Prevents Design Errors and Report Rejection

Incorrect shear strength results due to uncalibrated equipment can lead to unsafe designs, disputes, or rejection during audits and inspections.

Improves Equipment Reliability and Consistency

Calibration helps identify issues related to loading mechanisms, proving rings, load cells, or displacement gauges, ensuring consistent test performance.
