eyeglasses testing equipment testing process.
1. Pour the anti-sweat solution into the container to a depth of 10 mm, so that the low part of the specimen is exactly 15 mm ± 3 mm from the surface of the solution.
2. Place the frame on the stand, with the legs naturally open and the bottom edge of the legs resting on the stand to ensure that the specimen does not come into contact with other items.
3. cover the container, put it into the oven, keep the temperature at 55℃ soil 5℃, 8h soil 30 min, remove the specimen and wash it with water immediately, then absorb the moisture with a soft cloth without friction.
4. Under the same conditions as the test appearance quality, check each part of the specimen, compare with another specimen that has not been subjected to this test, and record the condition of the specimen.
5. Put the specimen into the holder again, cover the container, put it back into the oven, and keep it at the temperature point of 55℃±5℃ for 16 h±30 min. After a total of 24 h of test, remove the specimen and wash it with water immediately, and then absorb the moisture without friction with a soft cloth.
6. Under the same conditions as the test appearance quality, check the part of the specimen that is suitable for long-term contact with the wearer's skin (the inside of the temples and the lower edge of the rim), which can be compared with another untested frame, and record the specimen.
Standard requirements after the test, the frame long-term contact with the skin of the inside of the mirror leg and the lower edge of the rim should not have corrosion points, discoloration, plating rust, peeling or peeling, etc. If the test frame does not appear above phenomenon, it is qualified glasses.
