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.

Standard Test Method for Brinell Hardness of Metallic Materials
Brinell hardness is directly related to the strength and wear resistance of a metal sample. This information may correlate to tensile strength, wear resistance, ductility, or brinlel physical characteristics of metallic materials, and may be useful in quality control and selection of materials.
Standardization of Brinell Hardness Test Blocks. 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. Don’t hesitate to aks our sales engineers for more advice on our product range. Standardization of Brinell Hardness Asttm. Samples less than 0. Brinell testing machines Above you can find our Brinell testing systems.
The average diameter measurement can brinelk converted to a Brinell hardness number via the Brinell formula or a conversion chart based on the formula. Link to Active This link will always route to the current Active version of the standard.
Results are reported in a table format with one indent per sample.
Although this standard specifies the unit of force in the International System e1 Units SI as the Newton Nbecause of the historical precedent brindll 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. APM Testing provides A2LA accredited services for Brinell hardness testing at a fair price, with prompt delivery, and a detailed test report.
Brinell Hardness Testing
This standard provides the requirements for a Brinell testing machine and the procedures for performing Brinell hardness tests. Table of Brinell Hardness Numbers.
Most commonly used to test materials that have a structure that is too coarse or that have a surface that is too rough to be tested using another test method, e. Brinell Hardness Standardizing Machines. ASTM E10 is a method of determining hardness by pushing a ball into the surface of a metal and then measuring the diameter of the indent left by the ball.
The Brinell Hardness Test: ASTM E 10
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. Lower loads are used for small or soft samples. 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.
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. Above you can find our Brinell testing systems.
The tested surface must be relatively smooth and flat. 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 Advanced Plastic and Material Testing, Inc.

Historical Version s – view previous versions of standard. Brinell hardness gives good results for non-uniform brinnell such as castings since it has a large indent size.
Contact us for a quote. The result is in the form of a hardness number between and with a higher number indicating a harder material. Brinell testing e0 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.
Smaller samples can sometimes be tested.
