Organization: ASTM International
Publication Date: 10 March 1998
Status: inactive
Page Count: 5
scope:

1.1 This practice covers two levels of tests to measure the performance of laboratory Fourier transform near infrared (FT-NIR) spectrometers. This practice applies to the short-wave near infrared region, approximately 800 mm (12 500 cm-1) to 1100 mm (9090.91 cm-1); and the long-wavelength near infrared region, approximately 1100 mm (9090.91 cm-1) to 2500 mm (4000 cm-1). This practice is intended mainly for transmittance measurements of gases and liquids, although it is broadly applicable for reflectance measurements.

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.
