Keywords: Water vapor permeability; Water vapor transmission rate; Cup method; Membrane; ASTM E96. 1. Introduction The global energy consumption has risen significantly in the past decades due to the growth of population, to the increase in the thermal comfort desire and to the rapidly developing economy. Similarity #1 Both ASTM F1249 & E96 Are Intended to Measure Water Vapor Transmission. Both F1249 and E96 are designed and intended to measure the same thing: the amount of water vapor that passes through a section of a product over a period of time, based on a differential in partial water vapor pressure on either side.
