Do you know what glasses lenses you wear are tested? What test to do? It is Lens flame retardant test.

The purpose of our lens flame retardant test is to determine whether the material has the flame retardant properties required to ensure user safety.

There has been a lot of demand for this test recently, but it is relatively unfamiliar to most new labs. But don’t worry, I will tell you how to do the test here, what do you need to prepare for this test?

Test instrument requirements:

Can heat the regular cylindrical steel bar (φ6 * 300mm) resistance

Flammability tester with adjustable maximum temperature of 800 ° C, equipped with pneumatic device

Automatically raise and lower the heating rod to prevent the tester from touching the heating rod.

Testing method:

A. Determine the test location (different materials should be tested separately);

B. Place the test sample

C. Start the instrument and put down the heating rod when the temperature of the heating rod rises to 650 degrees Celsius.

The test sample is contacted for 5 seconds, and then the heating rod is removed;

D. Observe whether the tested part of the sample continues to burn.
