(Test Method)Standard Test Method for Gravimetric Determination of Nonvolatile Residue From Cleanroom Wipers
Standard Test Method for Gravimetric Determination of Nonvolatile Residue From Cleanroom Wipers
SIGNIFICANCE AND USE
The NVR obtained by this test method is that amount which is available for release by wipers in normal use.
Evaporation of the solvent at the stated temperature is to quantify the NVR that can be expected to exist at room temperature, since the slight difference between room temperature and test temperature has not been shown to result in significant variances.
This test method may be more aggressive than necessary for the evaluation of wipers that will be restricted to dry use only.
Numerous other methods are being used to determine NVR. This test method is not intended to replace test methods used for other applications.
SCOPE
1.1 This test method covers the determination of solvent extractable nonvolatile residue (NVR) from wipers used in assembly, cleaning, or testing of spacecraft, but not from those used for analytical surface sampling of hardware.
1.2 The NVR of interest is that which can be extracted from cleanroom wipers using a specified solvent that has been selected for its extractive qualities. Alternative solvents may be selected, but since their use may result in different values being generated, they must be identified in the procedure data sheet.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3.1 Exception—The inch-pound units are included for information only.
1.4 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.
