Abstract
A determination method is for an exhaust gas treatment device mounted in a work machine and having at least one of a diesel oxidation catalyst and a catalyzed soot filter. The determination method includes acquiring heat damage information, acquiring cumulative heat damage information, and determining a usability of the exhaust gas treatment device based on the cumulative heat damage information. The heat damage information indicates an extent of heat damage of the exhaust gas treatment device based on a unique identification symbol of the exhaust gas treatment device. The cumulative heat damage information is acquired by accumulating the heat damage information.
