Automatic ozone resistance tester for - dynamically sensitive elastomers |
摘要 |
Using a light intersection technique, the equipment measures the time taken from the beginning of the exposure to ozone until the appearance of a specified number of micro-cracks. The samples are scanned with a light intersection microscope and the counting carried out by a device, e.g. an F.E.T., and a suitable recorder. |
