ASTM E Brinell Hardness Test. The Brinell Hardness Test is the oldest method of hardness testing commonly used today. The Brinell test was invented in. Guidelines for Brinell testing machines and the procedures for performing Brinell hardness tests are standardized through ASTM E ASTM E Standard Test Method for Brinell Hardness of Metallic Materials.

Advanced Plastic and Material Testing, Inc. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
How it works A Brinell hardness testing machine makes an indentation in a material, the resulting impression, the permanent width of indentation, is measured across at least two diameters.
This information may correlate to tensile strength, wear resistance, ductility, or other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.

Brinell Hardness Testing
Although Brinell loads can be found ranging from 1kgf to kgf, most common scales use a testforce of kgf to Kgf and a 10mm ball indenter, so that the resulting indentation averages out most surface and sub-surface inconsistencies. Verification of Brinell Hardness Testing Machines. Results are reported in a table format with one indent per atsm.
Table of Brinell Hardness Numbers.
Don’t hesitate to aks our sales engineers for more advice on our product range. Although this standard specifies the unit of force in the International System of Units SI as the Newton Nbecause of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information and much of the discussion in this standard refers to forces in kgf units. Brinell testing often use a very high test load Kgf and a 10mm ball indenter so that the resulting indentation averages out most surface and sub-surface inconsistencies.
ASTM E10 – BRINELL HARDNESS TESTING SERVICES
Portable Brinell hardness testing machines that cannot meet the direct verification requirements and can only be verified by indirect verification requirements are covered in Test Method E Smaller samples can sometimes be tested. A Brinell hardness testing machine makes an indentation in a material, the resulting impression, the permanent width of indentation, brihell measured across at least two diameters.
Standardization of Brinell Hardness Indenters. Brinell hardness gives good results for non-uniform materials such as castings since it has a large indent size.
Material testing you can trust brinelo The average diameter measurement can be converted to a Brinell hardness number via the Brinell formula or a conversion chart based on the formula.

Above you can find our Brinell testing systems. ASTM E10 is a method of determining hardness by pushing a ball into the surface of a metal and then asstm the diameter of the indent left by the ball.
Lower loads are used for small or soft samples. Our laboratory also provides laboratory services for plastic testingmetal testingrubber testingoil testingpaint testingplating testingadhesive testingcircuit board testingand other testing.
Standard Test Method for Brinell Hardness of Metallic Materials
The result e0 in the form of a hardness number between and with a higher number indicating a harder material. Brinell hardness is directly related to the strength and wear resistance of a metal sample. Work Item s – proposed revisions of this standard. The tested vrinell must be relatively smooth and flat. APM Testing provides A2LA accredited services for Brinell hardness testing at a fair price, with prompt delivery, and a detailed test report.
This standard provides the requirements for a Brinell testing machine and the procedures for performing Brinell hardness tests.
