APM Testing provides A2LA accredited services for Brinell hardness testing at a fair price, with prompt delivery, and a detailed test report. Our laboratory also provides laboratory services for plastic testing, metal testing, rubber testing, oil testing, paint testing, plating testing, adhesive testing, circuit board testing, and other testing.

Purpose: Measure the Brinell hardness of a metal sample per ASTM E10.

Sample: One block 1 x 1 x 0.4 inches (25 x 25 x 10 mm) or larger.
Smaller samples can sometimes be tested.

Basic Description: 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 such as castings since it has a large indent size. There are multiple Brinell hardness scales such as 10/3000 which specifies a ball diameter of 10 mm under a load of 3000 kg. The result is in the form of a hardness number between 100 and 650 with a higher number indicating a harder material. Lower loads are used for small or soft samples. Samples which are too small to measure per ASTM E10 can be measured using ASTM E18 Rockwell Hardness or ASTM E384 Knoop Micro-Hardness. Brinell hardness is directly related to the strength and wear resistance of a metal sample. Results are reported in a table format with one indent per sample.

Limitations: The tested surface must be relatively smooth and flat. Samples less than 0.4 inches (10 mm) thick are usually too thin for accurate measurements.
