: Machine bearing faces or auxiliary steel platens must have a minimum surface hardness of 600 HV (Vickers hardness) to prevent distortion under extreme load pressures.

To ensure a uniform load, the loading surfaces of the specimen are typically capped, ground, or bedded to ensure they are perfectly flat and parallel. 2. The Testing Apparatus Both the BS EN 772 and BS EN

By following this standard, manufacturers and engineers can verify that building products are suitable for their intended load-bearing applications. Summary of the Testing Process

: Specimens are centered on the platens of a testing machine. A load is applied continuously at a specific rate until the unit fails. Calculation To ensure a uniform load, the loading surfaces

: Compressive strength is calculated by dividing the maximum failure load by the cross-sectional area of the specimen. www.thenbs.com Where to Access the PDF
