ASTM E1543-14(2022) PDF

Scope: 1.1 This practice covers the determination of the noise equivalent temperature difference (NETD; NE∆T) of thermal imaging systems of the conventional forward-looking infrared (FLIR) or other types that utilize an optical-mechanical scanner; it does not include charge-coupled devices or pyroelectric vidicons. 1.2 Parts of this practice have been formulated under the assumption of a photonic detector(s) at a standard background temperature of 295 °K (22 °C). Besides nonuniformity, examinations made at other background temperatures may result in impairment of precision and bias. 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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
