Outgassing can be significant if it collects in a closed environment where air is stagnant or recirculated. For example, new car smell consists of outgassed chemicals released by heat in a closed automobile. Even a nearly odorless material such as wood may build up a strong smell if kept in a closed box … See more Outgassing (sometimes called offgassing, particularly when in reference to indoor air quality) is the release of a gas that was dissolved, trapped, frozen, or absorbed in some material. Outgassing can include sublimation See more The outgassing of small pockets of air near the surface of setting concrete can lead to permanent holes in the structure (called See more • Outgassing Data for Selecting Spacecraft Materials Online (NASA database) • ESA Outgassing Data for Spacecraft Materials according to ECSS-Q-70-02 See more Outgassing is a challenge to creating and maintaining clean high-vacuum environments.

Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas. Alloys with good weldability under argon arc welding are usually chosen. • Mild steel can be used for moderate vacuums above 1×10 torrs (1.3×10 kPa).
