The Rockwell test is the most popular indentation hardness test and is used in a wide variety of applications. Advantages of the Rockwell Test There are several reasons for the popularity of the Rockwell test. The test itself is very rapid. On a manually operated unit, a Rockwell test takes only five to ten seconds,Bring material right to your bench to measure its hardness. These testers use a carbide indenter to take accurate Rockwell hardness readings every time. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. With a durable metal body, these testers stand up to many environments, from heat treat facilities to workshops to inspection labs.

4) For Rockwell hardness testing, no optical measurements are required; all readings are direct. There are two common methods applied to measure material hardness macroscopically: Rockwell and Brinell. Rockwell hardness differs from Brinell hardness testing in that the indentation size is measured in BrinellThe selection of test force is automatically adjusted once you select your hardness scale. There are three test forces of 60kgf(588.4N), 100kgf(980.7N) and 150kgf(1471N) for Rockwell hardness measurement, and also three test forces of 15kgf(147.1N), 30kgf(294.2N) and 45kgf(441.3N) for Rockwell superficial hardness measurement.
