Standard Practice for
Accelerated Weathering of Pressure-Sensitive Tapes by
Carbon-Arc Exposure Apparatus1

This standard is issued under the fixed designation D 3815/D3815M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

1. Scope

1.1 This practice describes one environment for the exposure of pressure-sensitive tapes to an accelerated weathering
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.

1.4 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.
