ASTM E932-89 (R2021) pdf free download.Standard Practice for Describing and Measuring Performance of Dispersive Infrared Spectrometers.
1 .1 This practice covers the necessary information to qualify dispersive infrared instruments for specific analytical applications, and especially for methods developed by ASTM International.
1.2 This practice is not to he used as a rigorous test of performance of instrumentation.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does 1101 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, health, and environmental practices and determine the applicability of regulatory lunitaflons prior to use.
1 .5 This imiternational standard was developed in accordance with uiternationallv recognized principles on standard— ization established in the Decision on Principles for the Development of Internatiomial Standards, Guides and Recommnendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Significance and Use
4.1 This practice is intended for all infrared spectroscopists who are using dispersive instruments for qualitative or quantitative areas of analysis.
4.2 The purpose of this practice is to set forth performance guidelines for testing instruments used in developing an analytical method. These guidelines can be used to compare an instrument in a specific application with the instrument(s) used in developing the method.
4.3 An infrared procedure must include a description of the instrumentation and of the performance needed to duplicate the precision and accuracy of the method.
5. Apparatus
5. 1 For the purposes of this practice, dispersive instruments include those employing prisms, gratings. or filters to separate infrared radiation into its component wavelengths.
5.2 For each new method, describe the apparatus and instrumentation both physically and mechanically, and also in terms of performance as taught in this practice.ASTM E932 pdf download.
