Scope

This Standard specifies the techniques and methods for material sorting of conductive
materials using direct and comparative thermoelectric potential sorters based on the
Seebeck effect.
This Standard is applicable to the sorting of metal materials, the piece-by-piece manual
sorting of metal workpieces and automatic sorting of large quantities of metal
workpieces. The identification and sorting of metal plating thickness, hardness and
hardened layer depth may take this Standard as a reference.
