Metallic materials. Brinell hardness test - Verification and calibration of testing machinesWhat is this standard about? 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

protection for safety

ISO 204 is concerned with the method used to measure such material behaviour

The standard also always incorporates any changes to legislation and lessons learned from incidents or its application since the last version was published

Reference should be made to BS 1377-1 for general requirements that are relevant to all parts of BS 1377-6

Materials that can be used for instrument calibration are needed

This is effective in retarding the formation of white corrosion products which form on zinc coatings under certain conditions

The purpose of this part of BS EN ISO 8362 is to specify the shape and dimensions of
