This standard specifies basic requirements, test methods, test rules and warranty period of imported used hydraulic excavator.
This standard applies import used hydraulic excavator below 90t (hereinafter referred to as excavator).
Excavator in this standard is excavator that possesses one of the following situations:
——still possess basic function and certain use value after being used;
——not being used but has been stored for a overlong time thus exceeding the warranty period or clear physical depreciation appears on the parts;
——assembled with new parts and used parts;
——after being repaired or renovated.
