Hardness test blocks are now widely known as another option of hardness tester. Hardness test blocks are mainly used for calibrating the production of hardness testers. They are heated in a vacuum heat treat furnace which is controlled b computer for providing you a great repeatability and consistency. For easier reading and high accuracy, they are mostly equipped with diamond polished.
Brinell Hardness Test Block
If you are looking for hardness test blocks, Brineel hardness test block can be your good option. This instrument is used for calibrating portable, bench, and production Brinell hardness testers. Each of the test blocks is heat treated in a computer-controlled vacuum heat treat furnace for insuring the optimal repeatability and consistency. In order to provide you impressions for easy reading with great accuracy, they are lightened with diamond polish.
Furthermore, Branell hardness test blocks are standardized along with five impressions. These instruments have met the certification from ASTM E-10 as well as ISO 6506 on hardness testers which are standardized and traceable to NIST.
The arithmetic mean of the five impressions is engraved on the block either in diameter in millimeters or BHN Hardness. Each test block is standardized with Tungsten carbide indenters. HB30 designates 3000 kg / 10 mm ball. It is the most common scale of Brinell. Meanwhile, HB15 designates 1500 kg / 10 mm ball, and HB5 designates 500 kg /10 mm ball.
Brinell hardness test blocks’ final inspection is performed in the state of the art ISO 17025 official laboratories. All types of test blocks are constructed with the revisions of the newest ASTM E10 from Brinell. Each of the hardness test blocks is equipped with a long form calibration certificate which is to verify the readings.
Meanwhile, the equipment for test measurement utilized was calibrated and traceable to NIST. This instrument is available in aluminum or steel with the hardness in the range of HB525 to HB75. The dimension of this test block is 6 inch long x 2-1/2 inch wide x 5/8 inch thick.
The features which are supplied to this type of hardness test blocks include 25 percent larger test block, amenable with the latest Brinell ASTM E10 Brinell Revisions, specific heat treat process which can provide you a repeatability and consistency, easy to read grain free surface, great de-carb free tool aluminum and steel, ISO 6506 accredited, NIST traceability, and also lifetime guarantee.
Rockwell Test Blocks with the latest Rockwell E18 Revision
Another option of hardness test blocks you can pick for your need is Rockwell test blocks with E18 Revision. It is able to provide you a fast and reasonable test. It comes with simple operation for easier use even with less skilled operator.
The test is very beneficial for selecting the material, controlling the process and quality, as well as for acceptance testing of commercial products. There are two categories of Rockwell hardness scales including regular and superficial Rockwell scales. Both use the same indenter type.
The regular Rockwell hardness testing scales utilize heavier load levels including 60 kgf, 100 kgf or 150 kgf. On the other hand, superficial Rockwell hardness testing scales utilize lighter load levels including 3 kgf, 15 kgf, 30 kgf or 45 kgf. Therefore, superficial is ideal for thinner materials.
The features which are supplied to this type of hardness test blocks are calibrated to ISO 6508, ISO/IEC 17025, (ISO) 10012-1, ANSI (NCSL) Z540-1, ASTM E18, high quality brass, steel, and aluminum, diamond polishes to mirror finish, great accuracy, special heat treat process for great repeatability and consistency.
