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.

This standard provides the requirements for a Brinell testing machine and the procedures for performing Brinell hardness tests. The average diameter measurement can be converted to a Brinell hardness number via the Brinell formula or a conversion chart based on the formula.
Historical Version s – view previous versions of standard. 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.
Work Item s – proposed revisions of this standard.
The result is in the form of a hardness number between and with a higher number indicating a harder material. 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 brimell units.

APM Testing provides A2LA accredited services for Brinell hardness testing at a fair price, with prompt delivery, and a detailed test report. Above you can find our Brinell testing systems.
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. 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 Most atsm 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.

Samples less than 0. 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.
Brinell hardness gives good results for non-uniform materials astj as castings since it has a large indent size. Standardization of Brinell Hardness Test Blocks.
ASTM E10 – 18 Standard Test Method for Brinell Hardness of Metallic Materials
Standardization of Brinell Hardness Indenters. 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, is measured across at least two diameters.
Lower loads are used for small or soft samples. Results are reported in a table format with one indent per sample. Brinell Hardness Standardizing Machines.
The tested surface must be relatively smooth and flat. Advanced Plastic and Material Testing, Inc.
Brinell hardness is directly related to the strength and wear resistance of a metal sample. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
