GB/T 3871.10-2006

This standard specifies the test procedures for evaluating the low-temperature starting performance of agricultural tractors. It is applied in the design, manufacturing, and type-testing of tractors to ensure reliable engine ignition and operation under cold climate conditions, typically at temperatures as low as -15°C or lower. The standard is used by manufacturers, testing laboratories, and regulatory bodies to verify compliance with cold-start requirements for tractors intended for use in northern regions or winter environments.
