ASTM D3815/D3815M-05
(Practice)Standard Practice for Accelerated Weathering of Pressure-Sensitive Tapes by Open-Flame Carbon-Arc Exposure Apparatus
Standard Practice for Accelerated Weathering of Pressure-Sensitive Tapes by Open-Flame Carbon-Arc Exposure Apparatus
SIGNIFICANCE AND USE
This practice does not necessarily provide direct simulation of natural weathering exposure.
Results from use of this practice shall not be represented as being equivalent to those of any natural weathering test until a satisfactory degree of correlation has been established for the material in question.
Variations in results are possible when the operating conditions vary within the accepted limits for the instrument specified in Practices G 151 and G 152.
SCOPE
1.1 This practice describes one environment for the exposure of pressure-sensitive tapes to a laboratory accelerated weathering environment.
1.2 This practice describes sample preparation and the laboratory-accelerated weathering 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.
Note 1—Practice D 6551 describes xenon-arc exposures of tapes.
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.
1.4 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.
