Oxygen transmission rate (OTR) of packages, pouches, moulded parts, bottles, etc. (only suitable for barrier materials, see also "i")
The measurement is carried out using the coulommetric, oxygen-specific carrier gas method.
Attention: This is only suitable for packages with a good oxygen barrier. Materials with high permeation coefficients, such as PP, PE or PS cups cannot be measured because the permeation is too high.
OTR package standard 23°C/ 50 % rel. humidity Testing program for packages which are stored under normal room conditions. Norm: ASTM F 1927
OTR package, refrigerator conditions (5 °C/ 50 % rel. humidity) Testing program for packaging materials used for packing products that are stored in the cold chain. Norm: ASTM F 1927
OTR package, tropical climate (38°C/ inside 50 %/ outside 85 % rel. humidity) Testing program for packaging materials used for packing products that are stored at elevated temperature and relative humidity. Norm: ASTM F 1927
