Plastics. Film and sheeting. Determination of gas-transmission rate - Differential-pressure methods Ingestion-build-61878 This helps you in detecting1 Scope This part of ISO 15105 specifies two methods for determining the gas transmission rate of single layer plastic film or sheet and multi layer structures under a differential pressure. One method uses a pressure sensor, the other a gas chromatograph, to measure the amount of gas which permeates through a test specimen.
