2. Take ten samples for each car as the wood sample for the car.
3. The sampling position should be representative. The upper, middle and lower layers of each car should be taken before, after and after.
4. The wood sample of each car is sent to the technical quality department for sampling by the sampler, indicating the type of wood chip, source of goods, car number, date, number and other information.
5. When taking the lower layer, you should take samples from the bottom of the car, and you can't artificially leak small materials.
6. During the sampling process, pay attention to the dry and wet conditions of the wood chips of the car. If the wet and dry is clear, all the wet pieces are taken as the wood chips of the car.
