Type test items
GD 12464-90
All common wooden boxes with new designs or structural materials and large process changes must undergo type tests, and their main test indicators are pressure tests and drop tests.
Pressure tests are in accordance with the provisions of 0B4857.4.
Drop tests are in accordance with the provisions of GB 4857.5. 7.2 Factory inspection
Before the products are shipped, the appearance, size, and material of the wooden boxes should be inspected one by one to ensure that the product quality meets the standards. 7.2.1 Box internal size inspection
Measure with a steel tape measure, and the allowable limit deviation is in accordance with the provisions of 6.2.3.3. 7.2.2 The thickness of the box board and the box railwww.bzxz.net
Use a vernier caliper to measure, and the allowable limit deviation is in accordance with the provisions of 1.4. 7.2.3 Material inspection
Inspect in accordance with the provisions of 6.1.3 and Table 8. 7.2.4 Determination of moisture content
The moisture content of ordinary wooden boxes is measured by a wood moisture meter. The box board is measured six times and the average value is calculated. The bottom board, side board, and end board (one side and end face are selected) are measured at 50mm along the edge of the board (bar) on both sides of the upper and lower ends in the length. If the tolerance is exceeded, it is considered unqualified. The measurement position is shown in Figure 4. .3 Inspection method and judgment rules
Joint version test product trial matching
Board measurement
When the products are delivered in batches, they should be sampled according to the method specified in GB 2828. According to the batch N, the normal inspection-time sampling plan is adopted for inspection. The general inspection level IL is IⅡ level: the qualified quality level AQL is 2.5 (can also be negotiated according to user requirements). If the number of unqualified judgments after random inspection exceeds the specified value, the number of samples should be increased, and the inspection plan should be tightened to continue inspection. If it still does not meet the specified value requirements, the batch of products will be judged as unqualified.

This standard is proposed by the Ministry of Materials of the People's Republic of China and the Ministry of Machinery and Electronics Industry of the People's Republic of China. This standard is drafted by Shanghai Timber Company and the Mechanical Standardization Institute of the Ministry of Machinery and Electronics Industry: Han Erling, Yu Lizhong, Fang Henian, Liu Huiyang, and Lu Hong are the main drafters of this standard. This standard refers to the Japanese industry standard JIS1402 "Wooden boxes for export packaging", the British standard BSI133 "Wooden containers and the Soviet national standard I0CT2991 ordinary wooden boxes below 500kg",4. The number of nails used is measured by the width of the box surface. The average number of nails is 1 for every 75mm. For single boards larger than 90mm, at least F-2. Two nails must be nailed to the upper and lower ends of the end boards above 200mm on the box surface. 6.2.3 Assembly of wooden boxes
6.2.3.1 Number of nails: Calculated by the width of the box surface, an average of 1 nail for 50mm (including steel strips). If the remainder is less than 30mm, add 1 nail (no less than 4 nails for widths below 190 mm). No less than 4 nails are used for corner wrapping! 6.2.3.2 The length of the nails is calculated by adding twice the thickness of the box board. 6.2.3.3 The limit deviation of the inner dimensions after the box is completed: length ± 5mm, width ± 3mm. Height ± 2mm. The box assembly method is shown in Figure 3.
7 Test methods and inspection rules
Type test items
GD 12464-90
All ordinary wooden boxes with new designs or structural materials and large process changes must undergo type tests, and their main test indicators are pressure tests and drop tests.
The pressure test is in accordance with the provisions of 0B4857.4.
The drop test is in accordance with GB 4857.5. 7.2 Factory Inspection
Before the product is shipped, the appearance, size, material, etc. of the wooden box should be inspected one by one to ensure that the product quality meets the standard requirements. 7.2.1 Inspection of the inner dimensions of the box
Measure with a steel tape measure, and the allowable limit deviation shall be in accordance with the provisions of 6.2.3.3. 7.2.2 The thickness of the box board and the box rail
is measured with a vernier caliper, and the allowable limit deviation is in accordance with the provisions of 1.4. 7.2.3 Material Inspection
According to Article 6.1.3 7.2.4 Determination of moisture content
The moisture content of ordinary wooden boxes is measured with a wood moisture meter. The box board is measured six times and the average value is calculated. The bottom board, side board, and end board (one side and end surface are selected) are measured at 50mm along the edge of the board (bar) on both sides of the upper and lower ends of the length. If the tolerance is exceeded, it is considered unqualified. The measurement location is shown in Figure 4. .3 Inspection method and judgment rules
Joint version test product trial matching
Board measurement
When the product is delivered in batches, it should be in accordance with GB 2828, and the sampling inspection is carried out according to the method specified in the normal inspection-second sampling plan according to the batch N. The general inspection level IL is IⅡ level: the qualified quality level AQL is 2.5 (it can also be negotiated according to the user's requirements). If the number of unqualified judgments after the random inspection exceeds the specified value, the number of samples should be increased, and the inspection plan should be tightened to continue the inspection. If it still does not meet the specified value requirements, the batch of products will be judged as unqualified.
