The GasMixType provides information about the gas mix, which is used in glass technology assembly and is formally defined in Table 47.

Gas_1 uniquely describes the first gas, which is part of the gas filling. The manufacturer and the material designation should be included.

Gas_2 uniquely describes the second gas, which is part of the gas filling. The manufacturer and the material designation should be included.

GasFilling defines the filling level of the gas in percent, for a filling of 100% the values is 100. For this variable are also values of more than 100 allowed, to represent an overpressure in the final product.

MixingRatio describes the ratio of the gas mixture. Here the value 0 means that only the first gas (Gas_1) is contained. If the parameter is 100 only second gas (Gas_2) is in the mixture. With a value of 50 both gases are contained in the ratio 1:1.

The component Variables of the GasMixType have additional Attributes defined in Table 48.
