Difference between Black Panel Temperature and Black Standard Temperature in Light Aging Test Chambers
In the light aging test chamber, black panel temperature and black standard temperature are two distinct temperature indicators. The black panel temperature is measured using a black metal panel sensor, reflecting the immediate heating effect on the material surface under light exposure and is significantly influenced by air convection.
Dart impact tester measures the toughness of packaging film.
The dart impact test evaluates the material's resistance to damage under dynamic impact, i.e., its toughness, by allowing a dart to fall freely and strike the packaging film. During the test, different impact energies are simulated by adjusting the weight of the dart or the drop height, and sensors are used to detect whether the film ruptures.
