Micom Laboratories offers ASTM D6551—Practice for Accelerated Weathering of Pressure-Sensitive Tapes by Xenon-Arc Exposure Apparatus—as part of its material testing services. This standard details an accelerated weathering test which allows to assess some physical properties of pressure-sensitive tapes through the use of UV testing. More specifically, this method only depicts the conditions that are required to do an accelerated weathering test of the samples and it is mandatory to pair the latter with another standard in order to appraise the physical characteristics of the specimens. Furthermore, ASTM D6551 relies on the use of Xenon arc light as an illuminating source and it is thus based on the ASTM G155 and on the ISO 4892-2 practices. Lastly, this method is not meant to gauge the aging characteristics of pressure-sensitive tapes used in an outdoor exposure for an extended period.
Accelerated weathering of pressure-sensitive tapes:
ASTM D6551 gives the guidelines of an accelerated weathering environment which allows to investigate some physical attributes of pressure-sensitive tapes that are mainly employed for packaging. Indeed, this method only states the apparatus parameters and the samples’ preparation for the exposure, but it does not mention any post-exposure evaluation tests. Thus, in order to appraise the properties of the specimen, this standard needs to be paired with another test protocol that allows to assess those attributes. For instance, it would be relevant to perform a peel test (ASTM D3330) or an adhesion resistance test (ASTM D3359) on the samples, because they characterize the core properties of tapes. Lastly, the test conditions are the same as those described in cycle 1 of the ASTM G155 practice.
Typical Experimental parameters for ASTM D6551 testing:
The number of samples required is three and their size will depend on the subsequent evaluation method. The specifications of the test are listed in table 1.
