The NEWAGE® 9000N Series makes a Brinell impression in conformance with the standard method for Brinell testing as described in ASTM E-10.  The impression made with the 9000N Series is measured based on the the depth of the indentation as described in ASTM E-103.  This technique offers higher productivity, faster testing and reduced operator influence.  

 

Like the Rockwell hardness method, the depth measurement used by the 9000N Series is calculated based on the difference in penetration depth between the preload (minor load) and the major load position.  During a test sequence, the 9000N Series applies a preload, zeroes the measurement, applies a full load, returns to the preload setting, and calculates the depth measurement.  An LVDT is used to measure the depth while a precision load cell is used to accuratey and precisely apply the loads.

 

For a given material, the depth measurement has been established to be linear to the width of the indention, however this relationship may change due to material characteristics such as elastic recovery.  Also, the ridge that is created and that forms around the impression may be higher on some materials, thus the width may vary. In order to compensate for this conditions, the 9000N Series may be programmed to
adjust its readout so that the measurement accurately reflects the linear relationship of width and depth. The compensation is determined by “benchmarking” the impression by first using an optical measurement and comparing the measurement to the 9000N Series displayed result.

The 9000N Series is comprised of a load frame, precision load cell sensor, LVDT for deflection measurement, hydraulic actuation system and our advanced electronics console. The 9000N Series performs all testing in the HB30 scale with a 10mm carbide ball and a 3000 kgf major load.
