(Practice)Standard Practice for Handling, Transporting, and Installing Nonvolatile Residue (NVR) Sample Plates Used in Environmentally Controlled Areas for Spacecraft
Standard Practice for Handling, Transporting, and Installing Nonvolatile Residue (NVR) Sample Plates Used in Environmentally Controlled Areas for Spacecraft
ABSTRACT
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.
SCOPE
1.1 This practice covers the handling, transporting, and installing of sample plates used for the gravimetric determination of nonvolatile residue (NVR) within and between facilities.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
