5. Q: Do we have video photos of the company's products for air-tight water pressure testing? Are there any reports on the acid and alkali resistance of the product?
Answer: We only conduct air-tight water pressure test after each group of products is assembled before shipment. There is no video at present. We can take pictures and provide them to the company in the next test. Our material itself has the characteristics of acid and alkali resistance, so there is no need to test it. Customers who really need our products will know more about the material. As long as they know our material, they will know how much acid and alkali resistance the material is.
6. Q: What are the testing standards for the company's products?
Answer: The company's products are tested by air-tight water pressure after each group of products is assembled: 4kg air pressure air-tight or 10kg water pressure test.
