The ASTM D3833/D3833M-96 (2019) standard test method is used for the measurement of water vapor transmission of pressure sensitive tapes. This method evaluates the tape's vapor transmission capacity at its smallest size (usually perpendicular to the backing), providing relative transmittance data. The test focuses on the tape's performance in wet conditions and indicates the tape's possible water vapor path. The results show the tape's vapor transmission rate and suitability, especially in practical applications, such as on surfaces such as cup flanges. This method is critical for evaluating the tape's effectiveness as a water vapor barrier.
