Standard Practice for Accelerated Weathering of Pressure-Sensitive Tapes by Carbon-Arc Exposure Apparatus

SCOPE
1.1 This practice describes one environment for the exposure of pressure-sensitive tapes to an accelerated aging environment.  
1.2 This practice describes sample preparation and the accelerating environment to which it shall be exposed. It does not specify the length of time of the exposure nor what tests shall be performed on the material following the exposure.  
1.3 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently, without combining values in any way.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
