This document specifies methods of direct and indirect verification of testing machines used for determining Brinell hardness in accordance with ISO 65061 and also specifies when these two types of verification have to be performed. The direct verification involves checking that individual machine performance parameters fall within specified limits whereas the indirect verification utilizes hardness measurements of
