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

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.
