Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes

Importancia y uso:

5.1 This practice accelerates the natural aging of pressure-sensitive tapes so that the response to the usual physical property tests changes to the same extent as with an exposure to approximately two years of natural aging when compared with the response to tests before aging.

5.1.1 Natural aging in this context means a continuous period of aging of tape in a closed fibreboard container (in darkness) in the variable climate of either the warm moist south, the warm dry southwest or the moderate midcontinent, USA.

5.2 The extent of change for one physical property should be expected to be different than for another property and so would also relate to different natural aging time.

5.3 An abnormal product lot may cause differences in testing response that throw off the expected time patterns.

5.4 Appearance of normal tape product will usually change only slightly on two years natural aging. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product.

5.5 There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is under a use stress.
