| Abstract: | Method of measurement uncertainty evaluation for Brinell hardness test results was introduced in the present work.Measurement uncertainty of different measurement hardness range were investigated respectively by considering kind of influence factors including standard hardness specimen shown value error, Brinell hardness machine, measurement shown value error. According to the actual testing conditions such as standard hardness specimen shown value error, Brinell hardness machine, measurement shown value error, consequence of measurement uncertainty presented in the paper could be used practically in our interior Brinell hardness testing. |

| Keywords: | standard uncertainty combined standard uncertainty expanded uncertainty Brinell hardness test |
