Scope

This Regulation is applicable to the initial verification, subsequent verification and in-
use inspection of industry platinum thermal resistance in the whole or part temperature
range of -200°C~+850°C and with the nominal value α of temperature coefficient of
3.851×10-3°C-1; as well as the industry copper thermal resistance (hereinafter referred
to as thermal resistance) in the whole or part temperature range of -200°C~+850°C
and with the nominal value α of temperature coefficient of 4.280×10-3°C-1.
