About This Item
ASTM D5791 is the standard guide for using probability sampling methods in studies of indoor air quality in buildings. It provides a technical framework for selecting samples in a way that supports more reliable indoor air quality studies and better data interpretation. By focusing on probability-based sampling, the guide helps users improve representativeness, reduce selection bias, and strengthen the credibility of building-related environmental assessments.
What is ASTM D5791?
ASTM D5791 is an ASTM standard guide that addresses how probability sampling methods can be applied in studies of indoor air quality in buildings. As a guide, it is intended to support planning and decision-making rather than define a fixed test result or product requirement. It is most relevant when a study needs a sampling approach that can better reflect building conditions and support consistent, defensible technical findings. The standard may be used as part of a broader indoor environmental quality workflow.
Where is ASTM D5791 used?
This guide is typically used in indoor air quality investigations involving buildings, where sampling design affects the reliability of the study. It may support environmental assessments, building inspections, and other technical reviews that depend on air sampling plans. ASTM D5791 is especially useful when project teams need a structured approach for choosing sample locations, sample units, or survey populations within a building. It helps align study methods with the goal of producing results that are more representative of actual indoor conditions.
Why is ASTM D5791 important?
ASTM D5791 matters because sampling design can strongly influence the value of indoor air quality data. A probability-based approach helps improve consistency, supports more defensible conclusions, and may reduce the risk of biased or incomplete results. For organizations involved in compliance reviews, quality control, procurement, or technical evaluation, the guide offers a practical reference for planning studies with greater confidence. It can also help teams communicate methods more clearly and support better comparisons across building assessments.
