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.
1.1 This test method covers the determination of nonvolatile residue (NVR) fallout in environmentally controlled areas used for the assembly, testing, and processing of spacecraft.
1.2 The NVR of interest is that which is deposited on sampling plate surfaces at room temperature: it is left to the user to infer the relationship between the NVR found on the sampling plate surface and that found on any other surfaces.
