About This Item
ASTM E1982 is the ASTM standard for open-path Fourier transform infrared monitoring of gases and vapors in air. It provides a technical framework for using OP/FT-IR methods to observe airborne constituents along an open path, helping support more consistent measurement and interpretation. As a standards document, it matters for users who need a recognized approach to infrared-based air monitoring, especially where reliable detection and documentation are important.
Purpose of ASTM E1982
The purpose of this standard is to guide open-path FT-IR monitoring of gases and vapors in air using a defined ASTM practice. It is intended to support a consistent approach to infrared measurements taken across an open atmospheric path rather than within a closed sampling system. In practice, ASTM E1982 helps users align monitoring activities with a common technical reference, which can improve comparability, method selection, and confidence in results.
Common use cases of ASTM E1982
This standard is commonly used where gases and vapors need to be monitored in air over an open path using FT-IR instrumentation. That may include environmental monitoring, industrial air surveillance, or other workflows where remote or continuous observation is useful. ASTM E1982 is also relevant when organizations need a documented practice for evaluating airborne compounds, supporting field measurements, or structuring monitoring programs around open-path infrared techniques.
Why ASTM E1982 matters
ASTM E1982 matters because it supports more consistent use of a specialized monitoring method that can be important for compliance, quality control, and risk reduction. When teams rely on open-path FT-IR data, a recognized standard helps improve technical consistency and supports clearer procurement and evaluation decisions. It can also help users compare systems and results more confidently by following a common ASTM framework for air monitoring practice.
