Test method
The sugar temperature in the test grid is %~
Forming heat for 0.5h:
b. The temperature should be raised to 95% within 3>5h and maintained at 4cT:±2. Within 15h, the temperature should be reduced to 25C±3 within 16hd.H. Keep the temperature still at % and stop measuring instrument. After stabilizing for 16--243, perform inspection by fast recording method on 5.1--5.14.
Put the packaged products on the table and start the competition according to the regulations. Then! The machine is to be tested according to the 5.1-5.13 clauses. The damaged surface is placed on the 2.5t gauge card, and the vehicle is driven at 40km/h on the 3 sections of 12.5-meter highway at a speed of 300xm. Then the test is carried out according to the 5.1~5.12 clauses. Note: The range of the gauge blocks used for the 17-meter test is as follows. The reading of the gauge block is used as the center for the measurement of the graduation value. 1, 3 gauge blocks are selected: the reading of the graduation value is above, 10, 21μrn is selected, and 5 gauge blocks are selected. Test rules. The micrometer test is divided into two types: "pick-up test" and "type test". 7.1 Factory control inspection
Products can only leave the factory after the factory quality inspection consultation. The inspection items signed by the factory should include the contents of 5.1~5.13. The inspection quantity 7.2 Type inspection
Micrometer type inspection items are 5.1-5.18. Sampling inspection shall be carried out from the products that have passed the factory inspection, and the number of samples shall not be less than 3. Type inspection is carried out when the following conditions exist: During the production trial and adjustment period of the transfer factory, when there are minor changes in the structure, materials and process after formal production, which may affect the product performance; During formal production, at least once every two years: Production interruption "is more than the previous production period, when the national quality supervision department puts forward a request. 3 Determine the standard: All items must be inspected for compliance during the type inspection, and the standard is the core product. If one item is found to be unqualified during the type inspection: Double sampling of detailed products should be conducted in the same batch of test instruments. , conduct inspection on the unqualified products, if there are still unqualified products, the type inspection will not pass.
