OBM Calibration Mass Certificate - Conditions of Issue

Conditions of Issue & Limitation of Liability

1. Purpose of This Certificate

This certificate is issued by NETCORP for the sole purpose of recording the vehicle's tare weight at the time of assessment. The process is intended primarily to support the calibration of NETCORP's onboard mass scale system, and is not a standalone guarantee of compliance with NHVAS, PBS, or any other heavy vehicle mass management framework.

2. Client Responsibility

It remains the sole responsibility of the client to determine whether this weighing process and resulting certificate meet their specific operational or regulatory compliance requirements. NETCORP does not warrant or represent that this certificate will be accepted by any regulatory body or third party for compliance purposes outside of internal calibration use.

3. Effective Weight Definition

The recorded tare weight represents the effective unladen weight of the vehicle in its normal operating configuration. For calibration purposes, this is defined as the vehicle being empty of payload but including:

• A full tank of fuel
• Full water tanks (if applicable)
• All standard fixed or fitted equipment
• A nominal driver weight of 100 kg
• This provides a consistent baseline for onboard mass calibration. Where a driver was not present during weighing, an adjustment factor is applied based on the assumed 100 kg standard.

4. Site Suitability & Axle Accuracy

Due to longitudinal slope or surface variation, not all weighing sites are suitable for accurately capturing individual axle group weights. Only sites that have been explicitly assessed and marked as suitable should be relied upon for axle split data. Overall gross vehicle mass (GVM) measurements are generally suitable for effective tare calibration and gross loading predictions, regardless of slope.

5. Adjustment Estimates

Where applicable, adjustment estimates may be used to compensate for missing fuel, water, or driver presence. These adjustments apply only to the gross vehicle weight and are not to be proportioned across individual axle weights. The Adjusted Effective Tare is provided for consistency in calibration and operational tracking.

6. Significant Tare Variation

If the measured tare weight differs significantly from previous baseline weights used in load factor calculations, it may be necessary to apply an additional adjustment to account for changes such as residual build-up or equipment additions. The client is responsible for reviewing this variance before relying on the data operationally or for compliance purposes.

7. Limitation of Liability

NETCORP accepts no liability for any direct, indirect, incidental, or consequential loss, penalty, or damage resulting from the use of this certificate or reliance on the data recorded herein. All use of this certificate is at the discretion and risk of the client.

8. Acceptance of Terms

By accepting and using this certificate, the client acknowledges and agrees to the above conditions and accepts full responsibility for determining the suitability of this process for their compliance or operational needs.
