Arti dan kegunaannya
1 Praktik ini mempercepat penuaan alami pita perekat yang peka terhadap tekanan, so that the response to ordinary physical property tests changes to the same degree as it does under exposure to natural aging for about two years, compared to pre-aging tests.

1.1 In this context, natural aging refers to the time of continuous aging of the tape in an airtight fiberboard container (in the dark) in a humid South, warm Southwest Southwest or moderately moderate U.S. climate change.

2 The degree of change in one physical property should be expected to differ from the degree of change in the other physical property and should therefore also be associated with different natural aging times.

3 Abnormal product batches can cause differences in test responses that exceed expected time patterns.

4 The appearance of normal tape products usually changes only slightly after two years of natural aging. This accelerated exposure often produces exaggerated changes in appearance that can only be seen in abnormal products under natural conditions.

In applications where tapes are subjected to usage pressure, there is currently no experience linking accelerated exposure to tape response.

Melangkah 1: Cakupan
1.1 This practice provides an environment in which the finished pressure-sensitive tape material can be exposed to accelerate its aging. It applies to roll tape when the user follows the precautions detailed in the procedure. The practice does not provide conclusions on its own, but is used in conjunction with cosmetic or physical characteristics testing to track accelerated exposure. Although this practice was developed using package-type tape, its use for other types of tape with similar structures is encouraged. Not applicable to electronic gradient bands (see Test method D1000).

1.2 Standar ini tidak dimaksudkan untuk mengatasi semua masalah keselamatan yang terkait dengan penggunaannya. Merupakan tanggung jawab pengguna standar ini untuk menetapkan keselamatan yang sesuai, spesifikasi kesehatan dan lingkungan dan untuk menentukan penerapan pembatasan peraturan sebelum digunakan.

1.3 Standar internasional ini didasarkan pada prinsip-prinsip standardisasi yang diakui secara internasional yang ditetapkan dalam Keputusan Prinsip-Prinsip Pengembangan Standar Internasional, Pedoman dan Rekomendasi yang dikeluarkan oleh WTO Technical Barriers to Trade (TBT) Komite.
