ASTM D6551/D6551M-05(2011)

This practice describes one method for accelerated weathering of pressure-sensitive tapes used primarily for packaging. It is not intended for evaluation the weathering characteristics of pressure-sensitive tapes used in long-term outdoor exposure conditions (see Practice D5105).

This practice does not necessarily provide direct simulation of natural 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.

Variation in results are possible when operating conditions vary within accepted limits for the instrument specified in Practices G151 and G155.

1.1 This practice describes one environment for the exposure of pressure-sensitive tape, used primarily for packaging, to a laboratory accelerated weathering environment.

1.2 This practice describes sample preparation and the accelerated 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 units 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 shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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.
