Brinell Test Blocks and Accessories

ASTM E-10, ISO 6506

All of our Brinell Test Blocks come certified to applicable standards. We adhere to a strict procedure for the calibration of these blocks, and the accuracy of the tester is maintained using a proving ring and load cell both traceable to N.I.S.T. The readings themselves are done using a stage micrometer also calibrated and traceable to N.I.S.T.

Note: Circle and gridded blocks available at additional cost. Dimensions for the most common blocks will be 6" x 2" x 3/4". The other dimensions are 6" x 41/2" x 3/4" or 2" x 2". It depends on ASTM E10-17 rules for dimensions. Call for prices and availability. The material used - steel, brass or aluminum depends on hardness.

 

 

Micro Hardness Test Blocks

ASTM E-92 - ISO 6507 & 4545
ASTM E-384 - ISO 6507

Our range of micro hardness test blocks exceeds industry standards. All of our micro test blocks are mirror-polished and mounted to provide the best possible test surface.

Each mirror-polished Heavy Load Vickers test block has the same surface area provided by our Rockwell test blocks, so that you get the most test opportunities for your money.

Micro Hardness Test Blocks

MV010                                 Vickers (1 gram to 1,000 gram) All Ranges

MV020                                 Heavy Load Vickers (1 Kg to 50 Kg) All Ranges

MK010                                  Knoop (1 gram to 1,000 gram) All Ranges

Note: When ordering please specify Knoop or Vickers, Load and the Hardness Range Number you require. On most Test Block Grids are available at additional cost.

Micro Hardness Accessories

P1110                                    Vickers Diamond Penetrator*

* Vickers Indentor available for most of the different makes. Please specify the make of your hardness tester when ordering.

P1120                                   Knoop Diamond Penetrator*

* Knoop Indentor available for most of the different makes. Please specify the make of your

hardness tester when ordering.

Note: Dual calibration on the same block is available upon request.
