This practice covers the proper procedures for handling, transporting, and installing sample plates used for the gravimetric determination of nonvolatile residue (NVR) within and between environmentally controlled facilities for spacecraft. This procedure shall appropriately require the following apparatuses and materials: Type 316 corrosion-resistant steel NVR plate; Type 316 corrosion-resistant steel NVR plate cover; noncontaminating nylon (polyamide bag); sealable aluminum NVR plate carrier; solvent compatible and resistant work gloves; oil-free aluminum foil; HEPA filters; and HEPA filtered workstation.
