Stainless steel thermal water cups are common products in modern life, and their quality is crucial to the user experience. In order to ensure the quality and performance of stainless steel thermal water bottles, manufacturers will conduct a series of tests before leaving the factory. Only after passing these tests can the product be deemed qualified. The following is a detailed introduction to the necessary testing content and qualification standards for stainless steel insulated water cups before leaving the factory:
1. Insulation performance test: This is one of the core properties of stainless steel insulated water cups. In this test, a water cup is filled with boiling or cold water, then the mouth of the cup is sealed, left for a period of time (usually 12 hours), and then the change in water temperature is measured. A qualified stainless steel insulated water cup should be able to keep the temperature of hot water not lower than a predetermined temperature within a certain period of time, and the temperature of cold water not higher than a predetermined temperature.
2. Sealing test: This test checks the sealing performance of the water cup. Fill the cup with water, seal it and then invert or shake it to see if leaks occur. Qualified water cups should not leak under normal use.
3. Appearance inspection: Appearance inspection is a key step to ensure that there are no obvious defects in the appearance of the product, including appearance defects, scratches, engravings, etc.
4. Material composition analysis: Through the composition analysis of stainless steel materials, ensure that the materials meet the standards and have no harmful substances or unqualified components.
5. Health and safety testing: The water cup comes into contact with food, so the health and safety of the material is crucial. Stainless steel materials are tested for health and safety to ensure no harmful substances are released.
6. Thermal stability test: This test is used to examine the performance of stainless steel thermos cups in high temperature environments. Fill the cup with boiling water and place it in a high temperature environment to see if its performance is affected.
7. Product identification and instructions: Ensure that product identification, labels, instructions, etc. are clear and accurate so that users can use and maintain the product correctly.
8. Durability test: Simulate the normal use of the water cup, such as falling, collision, etc., to test its durability and structural stability.
Qualification standards: Qualified stainless steel thermal water cups should meet the following standards:
Thermal insulation performance keeps the temperature stable within the specified time.
No leaks or leaks.
There are no obvious defects in appearance.
The material composition is safe and does not contain harmful substances.
Passed health and safety tests.
Good durability and not easily damaged.
To sum up, the necessary testing of stainless steel thermal water bottles before leaving the factory ensures the quality and performance of the product, so that consumers can buy and use it with confidence. The rigorous execution of various tests helps ensure the reputation and competitiveness of stainless steel insulated water cups in the market.
