scope:
This part of ISO 21760-2 specifies five methods for determining the water vapour transmission rate through the cross-section of an adhesive for edge seal in organic electronic devices such as organic light emitting diodes and organic photovoltaic cells.
The methods provide rapid measurement over a wide range of water vapour transmission rates.
NOTE Materials such as an organic layer and metal layer comprising the flexible organic electronic device are degraded by the penetration of a very small amount of water vapour. The hermetic lid and adhesive seal around the edges of the lid are required to have high barrier properties for the device as will be described in Fourth clause "Principle". The method for determining the water vapour transmission rate of adhesive is specified in accordance with one of ISO 15106-3, 5, -6, or -7.
