ASTM D6551 is a standard practice that provides a method for evaluating the weatherability of pressure sensitive tapes using a xenon arc exposure device. This practice outlines the exposure of pressure sensitive tapes to conditions that simulate weathering and provides guidance for measuring changes in the properties of these tapes after exposure.
This practice involves subjecting the pressure sensitive tape to a cycle of xenon lamp and water spray exposure. Light exposure is performed according to the specified irradiance and temperature, and water spray is performed according to the specified volume and pressure. Various properties of the tape, such as adhesion performance, color change, and physical integrity, were evaluated before and after exposure.
Manufacturers of pressure sensitive tapes often use this standard to evaluate the durability and performance of their products in different environments and under different weather conditions.
The purpose of this practice is to determine the resistance of pressure sensitive tapes to the effects of exposure to simulated weathering conditions including sunlight, heat and moisture.
The xenon arc aging test involves exposing a sample of pressure sensitive tape to a xenon light source for a specified period of time while subjecting the sample to humidity and temperature cycles. The samples are then evaluated for changes in color, adhesion, and other physical properties.
This standard is commonly used by manufacturers and users of pressure sensitive tapes to ensure that the tape is suitable for outdoor applications and will maintain its properties over time. It is also used by regulatory agencies to establish minimum performance requirements for these products.
