DPF의 판정 방법은, 제1 작업 기계(1)에 탑재되고, DOC(22) 및 CSF(23)를 포함하는 DPF(20)의 열피해 정도를 나타내는 열피해 정보를, DPF(20)의 고유 식별 부호에 기초하여 취득하고, 열피해 정보를 누적함으로써 누적 열피해 정보를 취득하는 취득 단계와, 누적 열피해 정보에 기초하여 DPF(20)의 사용 여부를 판정하는 판정 단계를 포함한다. 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.
