5.1 Test day
In order to determine whether the safety glass will show obvious changes and decrease in radiation protection ratio after a certain period of exposure, 5.2 Installation
5.2.1 Irradiation light source
Non-table British mid-point mercury hot vapor fluorescent lamp, the lamp housing must be self-contained. The nominal dimensions of the lamp are 3 mm long, 5 mm wide, 3 mm wide, and 5 mm wide. The ratio is w+0.
Any other source of illumination equivalent to the lamp specified above may be used. To check the efficiency of the used light source, the method is to determine the energy of the radiation within the range of 1 nm to 33 nm. Other wavelengths are filtered out with suitable filters. Therefore, filters should be added when using alternative light sources.
For safety reasons not related to this test, it is necessary to retest the test. 5.2.2 Power transformer and capacitor

f:76 mX800 5.2 Test procedure Determine the visible light transmittance of three test pieces of test film according to B151-2 (M2). Protect a portion of each sample so that it is not exposed to the light. Place the sample on a table 23 mm away from the lamp and make its length parallel to the lamp. During the test, scan the sample carefully at the temperature of three lamps. One side of the lamp should face outwards. After the irradiation time is 5.5 Expression of results Compare the transmittance of the sample before and after irradiation: The change is expressed in convexity scores. Color change assessment: Compare the difference between the irradiated area and the blocked area or delineate the three original coordinate systems of the sample before and after the irradiation. The International Committee of Technical Protection stipulates that the transmittance of each irradiated area should be 6 hours. 6.1 Test Purpose
Evaluate the appearance quality of the product after a certain period of time. 6.2 Test Procedure www.bzxz.net
Three test pieces of 30mm x 10mm are heated for 100-2000℃, and then cooled to room temperature naturally. The surface of each sample is not machine-cut. The sample can be vertically put into boiling water. Pay attention to avoid heat shock. 6.3 Results
Observe the gas cell discoloration and other defects produced in the test. Any cracks or defects that may occur within 15mm or 11mm are not machine-cut. If the cracks at the sample point are extended to the liquid consumption test range, the sample should be replaced with a test sample. 7 Humidity resistance test. 1 Test purpose: To determine whether the sample can withstand the effects of atmospheric condensation for a certain period of time. 7.2 Test procedure: Place the sample point in a closed container with a size of 500m×3m for 3 weeks. Keep the container temperature at 50℃ for 2 weeks and the relative humidity at 5%. Under the above conditions, no condensation should occur on the sample surface. If the sample surface is not tested during the test, leave an appropriate limit between the cracks to prevent condensation from dripping onto the test sample on the top of the container board and wall. The test sample should be made of finished products. The edge of the sample should be sufficient to cover the edge of the product. 7.3 Result Expression
