The International Standard Atmosphere (ISA) is an atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations.he International Standard Atmosphere (ISA) is an atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations.
Traceable Calibrations and Reference Standards. Here in the USA, most literature for flow instrumentation and/or instrumentation calibration services includes a statement explaining that the deviceâs calibration is NIST-traceable. Other countries may see similar statements such as PTB-traceable, or INMETRO-traceable calibrations.
