ASTM E2847

ASTM E2847 is the standard test method for calibration and accuracy verification of wideband infrared thermometers. It provides a structured way to assess whether these instruments are performing as intended, which is important for dependable temperature measurement in technical and quality-controlled settings. By focusing on calibration and verification, the standard helps users compare results more consistently and supports better confidence in instrument performance. ASTM E2847 is especially relevant when measurement accuracy affects testing, inspection, or process decisions.

What is ASTM E2847?

ASTM E2847 defines a test method for calibrating wideband infrared thermometers and verifying their accuracy. The standard is aimed at instruments that measure temperature without contact, where performance can be influenced by setup, target conditions, and the way readings are checked against a reference. As an ASTM standard, it provides a recognized technical framework for evaluating whether a thermometer is suitable for use and whether its readings remain within expected limits. This makes ASTM E2847 useful for controlled measurement programs and instrument validation.

Where is ASTM E2847 used?

This standard is commonly used in laboratories, inspection environments, and industrial workflows that rely on wideband infrared thermometers for temperature measurement. It is relevant wherever noncontact readings need to be checked against a known reference and documented for quality purposes. ASTM E2847 may also support procurement and maintenance programs when organizations need to verify instrument performance before routine use or after service. In practice, it helps users maintain consistent measurement methods across testing and calibration activities.

Why is ASTM E2847 important?

ASTM E2847 matters because accurate temperature measurement is essential for reliable testing and quality control. A defined method for calibration and accuracy verification helps reduce uncertainty, supports compliance expectations, and improves confidence in measurement results. For buyers and users of wideband infrared thermometers, the standard offers a clear technical basis for evaluating performance and comparing instruments. ASTM E2847 can also help reduce risk by identifying measurement issues before they affect product evaluation or process decisions.
