D3614-07 – Standard Test Method Technical Guide
🏛️ Scope and Organizational Framework
ASTM D3614‑07 (Reapproved 2021) establishes essential criteria for the selection, evaluation, operation, and control of laboratory organisations engaged in the sampling and analysis of environmental atmospheres. The standard covers ambient air, workspace environments, source emissions, and atmospheric deposition samples. Its foundational principle is that the utilization of well‑tested and uniform laboratory practices is essential for producing reliable and defensible environmental data whose validity can be demonstrated through comprehensive written field and laboratory records.
⚠️ Differentiating Standards for Air Quality Laboratories: Practitioners engaged specifically in source emission stack testing must refer fully to Practice D7036 for full administrative and technical competence.
