Abstract

The OIML R 111-1 requirements on magnetic properties such as the volumetric magnetic susceptibility (χ) and the magnetization of weights used in legal metrology. So far, these requirements cannot met by weights produced locally in Thailand. This research, therefore, aims to study manufacturing processes that may influence the magnetic properties. In order to reduce the magnetic susceptibility of the weights. Preliminary results show that the magnetic properties are stainless steel type dependent. Moreover, controlling process such as cutting, turning with lathe, grinding and heat treatment process can reduce the volume magnetic susceptibility of weights.
