The test is complete when equilibrium, or steady state, is achieved; that is, when the sensor detects a constant amount of oxygen in the nitrogen carrier stream. The rate of oxygen permeating through the sample is not changing. This rate is the sample OTR and is recorded in units of cc/100 in 2 /24 hr or cc/m 2 /24 hr at 73°F (23°C), 0% RH.

This report segments the global Oxygen Transmission Rate Test System market .C203H Oxygen TransmissionRate Test System is based on Coulometric oxygen analysis sensor andequal pressure test metod, and is conforming to ASTM D 3985 and otherstandards. . Transmission rate test of hazardous gases such as hydrogen and methane, etc. Transmission rate test of organic gases such as benzene, ester, alcohol and ketone, etc. Of interest are also basic oxygen transmission rates (OTR) through multi-layer sheets [4] or composite materials [5, 6]. Gas transport can be characterized with different methods [7] and oxygen permeation is investigated with approaches ranging from commonly used coulometric [1, 8] and galvanic [5] to fluorescence quenching sensing [9, 10].C206H Oxygen Transmission Rate Test System. C206H Oxygen Transmission Rate Tester, also Oxygen Permeability Tester is to measure OTR of packaging materials based on the coulometricsensor method and conforms to ASTM D3985.
Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description. In the world of oxygen permeation testing of packaging materials, not all instruments are created equal. This is why ASTM approved two distinct test methods for determining oxygen transmission rates of packaging . The OX-TRAN Model 2/21 10x oxygen transmission rate test instrument from Mocon accurately and repeatably measures films or packages at precise temperature and relative humidity conditions to 5x10-4 cc/(m2 x day), .

During thermoforming, plastic sheets are heated and subsequently deformed through the application of mechanical stretching and/or pressure. This process directly impacts sheet properties such as material thickness in walls, corners, and bottom, crystallinity in the constituent layers, and particularly the oxygen gas permeability. The aim of this study was to . Oxygen permeation can then be measured using three methods: Total pressure, isostatic and quasi-isostatic methods [].The first method includes the so-called manometrics and volumetrics, in which a pressure difference is generated on both sides of the membrane to be measured and the linear pressure increase is measured when permeation occurs using .1.1 This test method covers a procedure for determination of the steady-state rate of transmission of oxygen gas through plastics in the form of film, sheeting, laminates, coextrusions, or plastic-coated papers or fabrics.
