4.E.2 The base is mixed with industrial alcohol to make 1% red stock (the density of alcohol is not less than 10% of the dry red box, and the red box should be carefully reduced to remove the residue), and then rinsed and dried with water. The drying temperature is not higher than 100℃. The base is covered with a new layer. If there is always red liquid leakage inside, it is considered to be qualified. The current adsorption of the color on the surface of the base should not be used as the basis for judgment. When the supply and demand effect is set, select the red absorption method according to the heart B5514. 4.7 Storage and long-term fast
4.7,! The body has irregular end faces or steps that are obviously out of tolerance, and should not meet the requirements of Table 5. 4.7.2 Use daily testing gears for inspection. 5 Inspection rules 5.1 This standard is divided into acceptance inspection and routine inspection. 5.2 Acceptance inspection is carried out according to the routine inspection plan (2238). The test items, test parts, inspection level, and grid quality level should meet the requirements of Table 5. Test items External textile size, city map, medical change, three-line skin, test plan parts, "deep effect", inspection level, platform sink flux water AQ) Three words n2.30mm.

5.2.1 Each unit of the substrate is considered as one inspection batch. 5.2.2 The samples for shape and size inspection shall be drawn from the samples that have passed the acceptance inspection in Article 4.7. h.2.3 During the test, if the products meet the requirements of the table or the average, the batch of products shall be judged as qualified. If there are any violations, the batch of products shall be judged as unqualified.
5.3 Routine inspections shall be carried out according to the provisions of 4.3 and 5.2. Among them, the samples for item 5.2 shall be randomly drawn from the qualified products for acceptance inspection, and the inspection files shall be kept. They may also be sent to the test unit approved by the quality certification body for testing.
5.3.1 The inspection shall be carried out not less than once a year. When the manufacturing process or raw materials are changed, routine inspection shall also be carried out. 5.3.2 If all items in the routine inspection meet the requirements of this standard, the routine inspection is considered qualified. If any performance item does not meet the requirements of this standard, the routine inspection is considered qualified. When the routine inspection fails, timely notification shall be made and disposal restrictions shall be made.
