GB/T 2828.1 Sampling procedures for inspection - Part 1. The batch-by-batch test and sampling plan by the retrieval of acceptance quality limit (AQL) (GB/T 2828.1-2003, ISO 2859-1. 1999, IDT)
GB 3847-2005 The vehicular compression-ignition engines and smoke-emission limitation and measuring methods of the cars with compression-ignition engines instructions, it may conduct replacement and adjustment to the motor?€?s bearing, brush and other parts.
5.14 The wire and the insulating layer at -40??C shall have the nature of bending. 5.15 At the junctions of each sealing surface of heater, there shall not allow any gas leaking, oil spill and water leaking phenomenon. After igniting the heater for 15 min, the oil-drip tube shall be without dripping-leaking, and the drip volume of water pump shall be no more than 3 drops per minute.
5.16 The motor of the heater shall comply with the requirements of GB 755-2008. 5.17 Electrical components shall comply with the requirements of QC/T 413. 5.18 Painting and electroplating of the outer surface of the heater shall be color-consistent, uniform, firm, smooth, and beautiful; all kinds of fasteners and other exposed parts shall be performed by rust treatment such as spraying and enameling. Welding seam of each part shall be straight, uniform, without the burning defect, cellular, cracks, etc.
5.19 Heater shall be fitted with a fault-protection device. When occurring overheating, turning-off or failing to ignite, it shall turn off the heater. When it is in extreme-overturning, it shall automatically cut off the fuel flowing into the combustion chamber. Heart shall also be fitted with an external fuse or current fuse. When short circuit or overload, it can turn off the heater. Heater shall be installed at the position difficultly touched by people.
