As an important hardware accessory for doors and windows, the quality of copper glass hinges is directly related to the performance and safety of doors and windows. During the production process, copper glass hinges usually undergo a series of rigorous quality tests to ensure that their performance and quality meet the standard requirements. The following is a detailed introduction to the quality tests of copper glass hinges such as switch tests and salt spray tests:
1. Switch test
Switch test is an important means to evaluate the durability and reliability of hinges. In the test, the actual use of the hinge is usually simulated, and multiple switch operations are performed to verify its performance.
Test method:
Install the copper glass hinge on the test equipment to simulate the opening and closing action of doors and windows.
Set a certain number of opening and closing times (such as 200,000 times), and perform switch operations according to the set frequency and angle.
Observe and record the performance of the hinge during the test, such as whether there is looseness, abnormal noise, breakage, etc.
Test standard:
Different countries and regions may have different switch test standards for hinges. For example, the factory standard for European hinges is usually 80,000 openings and closings, while the domestic standard may be 40,000 times or higher.
Copper glass hinges should meet or exceed the corresponding national or industry standards to ensure their durability and reliability in actual use.
2. Salt spray test
Salt spray test is an accelerated corrosion test that simulates the marine environment or salty atmospheric environment, which is used to evaluate the corrosion resistance of metal materials. For copper glass hinges, salt spray test is an important means to test their surface treatment and material corrosion resistance.
Test method:
Put the copper glass hinge in a salt spray test chamber and set a certain salt spray concentration, temperature and humidity.
Let the hinge be exposed to the salt spray environment for a certain period of time (such as 24 hours to several days) and observe the corrosion on its surface.
Evaluate the corrosion level of the hinge, usually based on parameters such as corrosion area and depth.
Test standard:
The standard of salt spray test may vary depending on different products and application areas. For copper glass hinges, it is generally required to show good corrosion resistance in a salt spray environment.
High-quality copper glass hinges can usually pass higher corrosion level tests (such as level 10), which indicates that their surface treatment and materials have higher corrosion resistance.
3. Other quality tests
In addition to the switch test and salt spray test, the copper glass hinge may also need to undergo the following quality tests:
Appearance inspection:
Check whether the surface of the hinge is flat, free of scratches, oxidation and other defects.
Dimension inspection: Measure whether the various dimensional parameters of the hinge meet the design requirements.
Load-bearing test: Apply a certain load to the hinge to test its load-bearing capacity.
Hardness test: Test the hardness of the hinge to evaluate its wear resistance.
In summary, after the full copper glass hinge has undergone quality tests such as switch test and salt spray test, it can ensure that it has good durability, reliability and corrosion resistance during use. These tests are of great significance to improving product quality and ensuring user safety.
