　　One. Observing the vehicles, it was found that the wooden molds of this batch were rotten, indicating that the entire car was exported.

　　Take a bundle of wooden blocks and collect the following data

　　1. Bending detection:

　　1) The operator who malfunctions when the 4M curved metal passes within a range of 3 centimeters;

　　2) Within a range of 2cm for 3-meter wooden bent metal transmission, the count exceeds this fault.

　　Side bending, twisting, counting non-conforming products

　　4) If the unacceptable bending frequency of the wooden beam exceeds 5%, the vehicle shall be exported.

　　2. Acceptance of wooden edge leather:

　　If there is no edge leather or the thickness of the edge leather is less than 2cm and the length is less than 1m, calculate the qualified product

　　If the thickness of the edge skin is less than 2cm and the length is greater than 1m but less than 2m, it will be counted as a defective product

　　3) The thickness of the wooden blocks in Nanjing architecture is greater than the thickness of the skin, which is greater than 2cm2 cm on the skin side or edge, but the length is greater than 2M, and defects are considered.

　　4) If the number of defective wood edges on the skin of the bundle with wood proportion accounts for more than 5%, the vehicle is exported.

　　3. Measure the width and thickness of each wooden square on each side of the construction site, and the average of the actual dimensions of the wooden square in the middle shall prevail

　　1) If the actual size is greater than 4.2 cm x 7.2 cm and less than 5cm x 8 cm, then the product is qualified;

　　2) If the actual size is less than 4.2 cm x 7.2 cm and greater than 4 cm x 7 cm, the operator has a defect;

　　If the actual size is less than 4cm × 7cm or greater than 5cm × 8cm, it will be counted as non-conforming products;

　　4) If the number of failed wooden bundles accounts for more than 5%, the vehicle shall be exported.

　　4. Length detection of wooden blocks:

　　1) If the length of the 4m square timber in the northeast area of the Nanjing square timber strip exceeds 3.95m, it is considered a qualified product. If it is less than 3.95m but greater than 3.8m, it is considered a defective product. If it is less than 3.8m, it is considered an unqualified product;

　　In the Northeast region, if the length of a 3m wooden square exceeds 2.95m, it will be counted as a non-conforming product, and if it exceeds 2.8m, it will be counted as a non-conforming product

　　3) 4 meters of other wood with a length of 3.9 meters. Areas with a length greater than or less than 3.9 meters, greater than or less than 3.7 meters, and less than 3.7 meters are considered defective operational defects, and the number of defects is counted;

　　For other areas where the length of a 3m wooden square exceeds 2.9m, qualified products shall be calculated as unqualified products with a length greater than 2.7m but less than 2.9m and unqualified products with a length less than 2.7m;

　　5. Crack and damage detection

　　In case of cracking, the length of the damage is within 50cm

　　2) If the China Railway Special Square Wooden Strip Factory cracks it, consider a 50 centimeter or longer damage with defects.

　　Unqualified quantity exceeds 5% of a bundle of wood

　　6. Calculate the quantity of the above-mentioned inferior and unqualified products using China Railway Bureau's special square wooden strips, divided by the number of wooden bundles,Architectural timberObtain the proportion According to the proportion of the total number of wooden blocks in the vehicle, defective and non-conforming products shall be converted into qualified products by 70%, and non-conforming products shall be deducted If there are 4000 wooden blocks in the entire vehicle, and there are 20 defects and 5 non-conforming products in the selected 200 items, then the number of defective wooden blocks in the vehicle is 4000 × (20/20)=400, and the number of non-conforming wooden blocks is 4000 × (5/200)=100, resulting in a qualified quantity of 4000-400-100=3500. Therefore, the number of defective products is converted to 400 × 70=280. So the number of wooden beams received by the car should be 3500280=3780.
