Standard Test Method for Gravimetric Determination of Nonvolatile Residue (NVR) in Environmentally Controlled Areas for Spacecraft

Importancia y uso:

5.1 The NVR determined by this test method is that amount that can reasonably be expected to exist on hardware exposed in environmentally controlled areas.

5.2 The evaporation of the solvent at or near room temperature is to quantify the NVR that exists at room temperature.

5.3 Numerous other methods are being used to determine NVR. This test method is not intended to replace methods used for other applications.
