Abstract
A method for obtaining a heating element for an electronic vapor provision system includes providing a sheet of electrically conductive porous material, measuring amounts of light transmitted through at least two locations on the sheet to obtain a set of optical transmission values including a maximum value and a minimum value, comparing a difference value calculated from the maximum and minimum values with a predetermined acceptable variation in optical transmission, and selecting the sheet for use as a heating element if the difference value falls within the acceptable variation.
