Measurement of water vapour transmission

It applies to the in situ determination of the water permeability of an existing geological formation or of treated or compacted materials

it is first necessary to check the simulation method by using an appropriate reference model that is provided in BS EN 50318

Photography. Synchronizers, ignition circuits and connectors for cameras and photoflash units. Electrical characteristics and test methods Ingestion-build-54371 Measurement of water vapour transmission1 Scope This International Standard specifies the electrical requirements of the camera synchronizer, the ignition circuit in the photoflash unit and the cable to connect these, and the test methods to secure positive firing of the photoflash unit.
