Scope

Scope: This standard establishes the test methods, measurement equipment and instrumentation, and accuracy requirements for cold starting of construction machinery under polar operating conditions, as well as the test conditions, preparation, process, and deliverables. This standard applies to wheeled loaders, excavators, graders, skid steer loaders, milling machines, and other construction machinery operating under polar conditions. Main technical content: 1. Measurement equipment and instrumentation and accuracy requirements: Prepare the necessary equipment according to the test needs, including data acquisition recorders, current clamps, voltage sensors, thermocouples, engine CAN signals/speed sensors, pressure sensors, air pressure, and humidity meters, as well as a low-temperature environmental test chamber, and specify the accuracy of the measurement equipment. 2. Test conditions: This section elaborates on four main aspects: engine condition requirements (i.e., the temperature requirements for lubricating oil, grease, fuel, and coolant used in diesel engines); oil requirements (i.e., how to select oils for the hydraulic system and transmission system); temperature requirements (monitoring the oil temperature of the test target and the test environment temperature); and test environment conditions (i.e., specifying the test environment temperature and atmospheric pressure). 3. Test preparation: This section elaborates on four main aspects: checking the condition of the prototype, measurement parameters, requirements for test point layout, and test debugging. 4. Test process: This section elaborates on four main aspects of how to determine whether the engine has successfully started. 5. Safety requirements: This section outlines requirements related to safety during the operation process. 6. Test deliverables: Includes the start-up results and the start-up process curve chart.
